Whenever you come across this issue, it is possible that the app is harmful to the device. We’ve compiled potential fixes to avoid the error in this article.

Why is this app blocked by System Administrator?

There can be several reasons why you’re getting this app has been blocked by your System Administrator error message. Below are some of them;

Windows Defender or SmartsScreen has blocked the app – This error message may appear for security reasons if any application appears to pose a risk to your desktop. Your Windows PC comes pre-installed with Windows Defender and SmartScreen which scans your computer for malicious software and phishing attacks.

Third-party Antivirus Software – The issue is similar if you’re using a third-party antivirus program that might assume the app you’re trying to download is infected.

Applock enabled by Administrator – Only the Windows Professional edition is affected by this problem. It is likely that the administrator of the domain network to which your computer is linked has set specific Applock policies that limit the downloading of programs.

Access Restricted by Administrator – There may be restrictions on the updates and features you can use if Windows is running under the default account rather than an administrative account.

Outdated Application – Another reason for this problem could be that the software has been withdrawn by the developers or that the current version of Windows does not support your application.

Now that you know some of the potential reasons behind the error, the next section will provide you with simplified step-by-step instructions on how to fix the issue.

What can I do if I get this app has been blocked by your System Administrator?

Restart your PC.

Ensure that the application is safe to download and will not affect your PC.

Disable the security settings hindering the launch of the app.

1. Unblock the App from the Properties

Expert tip:

2. Disable SmartsScreen temporarily

Disabling the SmartScreen for a period will allow for the application to download without any hindrance. However, do this only if you’re sure the app is safe.

3. Disable third-party antivirus software or make app exception

If turning off the SmartScreen still doesn’t let you download the app, third-party antivirus software may be blocking it. The software allows you to either disable the application or set an exception just for it.

4. Run the app as an Administrator

To fix this app has been blocked by your System Administrator, you can run the file as an administrator. In case you encounter problems with command prompt, you can explore our dedicated guide to fix it.

How To Tell If Your Phone Has Been Hacked?

If you see suspicious things happening on your phone, like a new app you didn’t install or charges on your bill that don’t make sense, it’s possible that it’s been hacked.

Some of the most common methods hackers can use to hack your phone are:

Social engineering: Another common method hackers use is social engineering, which mainly exploits the human aspect. They manipulate our psychology/ emotion to get the required information for the attack. It could be as simple as asking for a password straight up for Wi-Fi or an OTP code.

Keylogger: Hackers can use keylogger software to track and record every keystroke you type, including account login credentials. Such programs get into your devices through malicious apps or any other form of malware.

Nonetheless, there are still some subtle signs that your phone is likely hacked or infected with malware.

If you see any unrecognized apps, you shouldn’t open them and consider uninstalling them immediately for your safety.

The major reason someone would try to hack your phone is for financial benefit. So, if you find any unknown purchase made from your phone, check the SMS alerts sent by your digital wallet or banking app. Furthermore, you can also download the entire list of your financial statements to review all your purchases.

If you get a message such as “Your phone is locked” or similar, your phone is probably hacked. In these cases, you cannot access your files, media, or documents and could be asked for a ransom to retrieve them. These are special types of malware called ransomware and are hard to get rid of. Also, there’s no guarantee that you will get your files back even if you pay the ransom.

A phone’s performance drops gradually after a certain point in time. However, it isn’t normal if the performance drops significantly and your phone suddenly becomes too sluggish.

Similarly, your phone can heat up abnormally even when you don’t seem to have any open applications, and the battery drains too quickly. Also, your phone may behave erratically and restart multiple times for no reason.

All the signs above indicate that a background process, most likely a virus/malware, is running in the background, hogging up your memory and taking control of your phone.

Sometimes your call history looks different, and unknown phone numbers exist without your knowledge, even when you haven’t actively used your phone. Also, some messages have been deleted, or there are unknown text messages. In these cases, your phone might have been in the control of the attackers. Or the text message could be malicious.

These days, scammers use this tactic to request money from people on your contact list, impersonating you when in reality, the money is being transferred to them.

In some cases, you are logged out of any account automatically on your mobile phone. And when you try to log in, you keep getting an error message like “Incorrect password” even though you entered the correct one.

If your password has been compromised, your phone might be hacked, and its passwords might have even been leaked online by hackers.

If you ever feel like your mobile data is being consumed more than usual, a third person might be using them to secretly upload your private information to their server. In such cases, your phone has abnormally high data consumption even when you haven’t utilized any data.

On Android devices, you can view the data usage graphs through the Settings app and check if the data traffic is unusual.

Instead of being a victim of a possible scam or hack, you should try to avoid/prevent them by being aware of the signs like the above. To prevent such incidents, you can do the following things.

Passwords are the key component when it comes to your device security. Whether it be your lock screen or your Google Account, the perpetrator can do severe harm if they get their hands on the passwords.

Therefore, you should always use a strong password that contains a combination of all kinds of characters; symbols, letters, numbers, etc. Also, consider using a longer password as it can withstand most brute-force attacks than a shorter one. To easily manage passwords, consider using a password manager.

On the other hand, don’t use the same password for every site you sign up for. It’s because if one of the passwords gets breached, others can also get compromised.

While a strong password is a great way of keeping your device safe from hackers, you should also consider turning on two-factor authentication. This adds an extra layer of security by requiring you to provide multiple passwords/information before you can finally log in to the account.

Public Wi-Fi is one of the most exploited methods used by cybercriminals to hack your smartphones. Such Wi-Fi connections are generally unencrypted and thus easier for them to hack and exploit.

Hence, you should avoid using public Wi-Fi, and in case of emergency, access the Internet through a VPN for a secure connection. Also, refrain from performing any financial transactions while using such Wi-Fi.

Another common way a hacker can get his hands on your device is when you install malicious apps from an external source. Therefore, you should only install apps from the official Play Store/ App Store.

If you have a habit of leaving your phone unlocked, other people can easily access its contents. So, consider signing out of your social media account when not in use. Or, at least secure your phone with a password/PIN to prevent it.

If your phone is running on an older version or has an outdated app, it may contain several bugs and issues which can be exploited by the bad guys. Such weaknesses are even circulated among illegal hacker forums, which means phones with older OS are easy prey for them.

Phone manufacturers and app developers constantly release newer versions of the app to fix the device’s previous vulnerabilities with the latest security patch. Therefore, you should always keep your phone and the apps updated to avoid such risks.

While some people root their Android phone for further customization, it isn’t recommended. Doing so voids the warranty, and you may not get any security updates for the device, which makes you vulnerable to malicious exploits.

Although saving passwords and enabling autofill on a browser is easier, it’s an unsafe practice. Any person, not necessarily a hacker, with physical access to your phone can easily log into websites and view your personal information.

You should always try to avoid getting into situations where your phone gets compromised in the first place. However, if you somehow fall into the trap and suspect your phone is hacked, you should consider doing the following things.

In case any of your accounts are breached, you should immediately change all their passwords. And, if the Google account is compromised on your Android device and you cannot change your password, you can reach out to Google Support.

If your phone is hacked, it most likely contains malware. Therefore, install a reliable antivirus app and use it to scan and remove all the potentially harmful software or viruses on your phone.

Resetting your phone clears all your phone contents and restores it to its initial configuration. All the malware or viruses are also wiped off along the process. However, consider backing up your files and other contents before doing so.

The moment you notice any suspicious activity on your phone, especially if you get a notification of an unknown purchase, you should immediately contact your financial institution. Then, ask them to freeze your accounts so that you can prevent further financial losses.

How To Tell Google Your Content Has Been Updated

Editor’s note: “Ask an SEO” is a weekly column by technical SEO expert Jenny Halasz. Come up with your hardest SEO question and fill out our form. You might see your answer in the next #AskanSEO post! 

Welcome to another edition of Ask an SEO! Here’s today’s question:

For an already existing content, if it is updated, how can we indicate to Google that it has been revised?

We have seen that in some cases Google picks on its own while in some cases the update is ignored and it crawls the story on its own frequency.

Is there a rule around what proportion of the story should be updated for Google to realize that an update has occurred?

There’s not a rule per se as to how much content needs to be updated, but you can use your common sense.

If all you change is a few words or a date, or just add a picture for example, you aren’t really changing the content.

People like to try to game this system by moving paragraphs around but not really changing the point of an article, for example. Google is wise to this and will not reward you for it.

However, if you have an article like “5 Predictions for SEO in 2023” and you update it to be “5 Predictions for SEO in 2023” and actually change most of the content, there are ways to help Google find out about it more quickly.

But before I share that, I want to be clear: the content needs to be different.

You can’t just post the same five predictions you made in 2023 and put them in a different order.

You can’t use four of the same five and just change one.

That’s not going to fly.

I use a real-world test. If I sent this article via email to my loyal followers, would they find value in it, or would I be irritating them by sending the same thing I previously sent?

Google is likely to react similarly.

If your content changes pass that real-world test, the best thing you can do is go into Google Search Console and resubmit the sitemap that contains that page.

Google will usually grab the new page in a couple of days.

If you really need it to be indexed right away (like if it’s time-sensitive content), then often doing a Fetch as Google for the page in Search Console will get it crawled within hours.

Don’t abuse that though – like anything else, if you submit all of your pages all of the time, you’ll dilute the importance of all of them.

Remember, Google will generally trust you until you give them a reason not to.

Fix This App Can’t Run On Your Pc Error On Windows 11/10

How to fix This app can’t run on your PC error message on Windows 10? You may have probably received this message pop up on your computer screen when you tried to run a just-installed software, run an app after a long time or tried to run a program after you installed some updates. Well if you have this question then this post suggests some setting you need to look at and shows you how to resolve the issue.

This app can’t run on your PC

Several users have received this message when trying to install iTunes, Lotus SmartSuite, Simple Assembly Explorer, AutoDesk, Daemon Tools, etc. But this message could appear for any app.

If you see this message, well the first thing you need to do is check if the software has some updates. Visit the software publishers site and ensure that you are running the latest version of the app. If you find that a new version has been released, download and install the new version. This should help. If t does not, there may be other things you may need to do.

Check if the program is meant for your version of Windows

Fresh-download the program

Log in with your Administrator account

Run the executable instead of the shortcut

Disable your SmartScreen

SideLoad the app

Troubleshoot in Clean Boot State.

1] Check if the program is meant for your version of Windows

Check it is meant for 32-bit or 64-bit. Maybe you are using Windows 32-bit and are trying to unknowingly run a 64-bit program. This is very common – so check if you are running Windows 32-bit or 64-bit first, and then install the app for your version. This issue can also occur if you are trying to run some old 8-Bit or 16-Bit app on your modern 64-Bit OS. It may have worked on a 32-Bit OS, but work on a Windows 64-Bit OS as it can emulate only 32 Bits.

2] Fresh-download the program

At times the download can get corrupted, so clear your browser cache and download and install the program again and see.

3] Log in with your Administrator account 4] Run the executable instead of the shortcut

If it is the program shortcut that is giving this problem, open its Program folder and see if you can run the main executable from there.

5] Disable your SmartScreen

As a temporary workaround disable your SmartScreen and see if it helps. Make sure that you enable SmartScreen again as it is a good security feature.

6] SideLoad the app

If you downloaded the app package, not from the Windows Store, but from another source, then assuming you trust the app publisher, you may need to SideLoad the app. One should SideLoad apps only when trusts them completely.

7] Troubleshoot in Clean Boot State

Perform a Clean Boot and see if you can run it. If you can, then you will have to manually identify and eliminate the offending process that is blocking Windows from running the app in normal boot. Remember to exit the Clean Boot State once you complete troubleshooting.

I hope something here helps you resolve the issue.

See this post if you receive a This app has been blocked for your protection message.

Update: Neo N003 Review – Has It Been Worth The Wait?

Neo N003 Background

The story of the Neo N003 started way back at the start of the year with rumours of a quad-core phone with 5-inch 1920 x 1080 display that would cost just $130 (799 Yuan). This wasn’t a rumoured price but a figure Neo actually gave to us when we asked and one they used to promote the phone.

Months past with very little in the way of Neo N003 news and then finally we got word that it would launch and it would be updated to a 1.5Ghz MT6589T processor. This could have been great news, but in the time that Neo had spent to develop the N003 rivals from iOcean, UMi, FAEA, Zopo and others had already established themselves on the market and easily available!

Neo N003 features

Being the last on the market isn’t necessarily a bad thing, and what Neo had done with their time developing the phone was to add practically every function and feature we could possible want from a current generation phone!

As mentioned above they had updated the quad-core chipset to a 1.5Ghz MT6589T processor, there is also an option of either 1GB or 2GB RAM, 13 mega-pixel rear camera, 3 mega-pixel front, 5-inch 1920 x 1080 FHD display, a Yamaha audio chip, Android 4.2, Ashahi tempered glass, dual SIM support, OTG, MHL and a 3000mAh battery!

Neo N003 specifications

[komper pid=27,28 compareform=no]

Neo N003 Unboxing Video

Neo N003 Review Neo N003 design – Not the prettiest, but one of the best made.

[komper pid=27,28 compareform=no]

I can only give you my personal opinion, and personally I didn’t really like the look of the Neo N003 from what I had seen in leaked photos and early hands on. When our Neo N003 test phone arrived I didn’t really expect to like it in the flesh either.

I don’t like the mixture of colours. I would have preferred it if Neo had gone for a black alloy surround rather than the silver one to create the popular ‘Panda’ look as seen on the JiaYu G4 and Xiaomi phones.

The silver and black together make me think of the old iPhone 3GS which is now a rather old-fashioned device, and I don’t like my leading hardware looking vintage from the get go (retro I can handle).

So from a looks perspective the N003 would be quite low on my list of possible phones, however build quality and finish are more important to me and this is where the N003 does very well!

The Neo is sturdier than similar handset from Zopo, but not quite as stiff as the JiaYu G4 or Xiaomi phones. There is a little flex in the body, but I believe you would have to be of ample frame to break the phone by sitting on it.

The plastics used on the rear the removal rear are very high quality. There is just enough give for the case to snap on and off easily, but is isn’t a thin or flimsy affair we see on many over phones.

Quality of manufacture is spot on too. Gaps are minimal and everything sits snuggly together.

Looking around the phone we find all the usually buttons and controls in the usual places. Back-lit capacative buttons on the chin, 3 mega-pixel front camera above the screen and by proximity and light sensors (there is also an LED notification light), make up the front of the phone.

The left hand side houses the power button which can also be used to lock and unlock the display.

Volume rockers are on the left and are in easy reach of an index finger (right-handed operation) or a thumb (for leftys).

A slightly protruding 13 mega-pixel camera sits on the rear. The lens is protected by an alloy ring, and there is a single LED flash below it. A interestingly styled rear speaker is also present as are the Neo logo, markings for the camera and an odd slogan reading “With Neo Team Sense”, whatever that might mean.

Everything is where you would normally expect things, except the micro USB which is there for charging, moving files or USB OTG is at the top of the phone rather than the base and sits next to a 3.5mm headphone jack.

Overall, the Neo N003 isn’t the best looking Android phone on the market but it is better made than most with better materials and fit.

Neo N003 display – Just what you expect from 1080p

Like many of it’s rivals the Neo N003 has a 5-inch display with a resolution of 1920 x 1080. With a full 1080 HD display you would expect a pretty crisp picture and you will not be disappointed.

Really if you have seen a 5-inch 1080 display on the UMi X2, FAEA F2 or iOcean X7 you will know exactly how good the display is on the Neo.

It’s been rather sunny here in so I have been able to test the display in some pretty harsh lighting conditions. With the screen on its brightest settings you can easily use the phone in really sunny conditions.

Colours, brightness and viewing are all on par with rivals such as the Zopo ZP980 and Zopo C2, however for touch sensitivity, responsiveness and accuracy the N003 is better than the current Zopo options, and is very reactive us use.

Neo N003 performance – Surprising for 1GB, gamers will still want more.

As the Neo Advanced with 2GB RAM wasn’t yet available when we received our phone for review we were sent the 1GB RAM phone. The Neo N003 basic is the same phone as the Advanced with with only 4GB memory and 1GB RAM.

Although the Neo does feel quite responsive in most situations there is some notable lag now and then when moving from one screen to another. This is particular notable on the the home screen and in the apps draw, but it seems to only really affect these areas and in app scrolling is good.

Update: At the request of Evgenij I have installed and tested Nova Launcher to see if the lag persists. With Nova launcher installed the Neo is lag free and more more responsive when swiping through the home screen.

With only 1GB RAM launching games can take a little time too, but once things are up and running performance is acceptable.

In the below video we test Rip Tide GP2. The Neo N003 handles the game play very well, but if you take a good look at the water effects, speed blurs etc it doesn’t look to us that the Neo N003 Basic can handle everything which is going on in the screen as fluidly as a phone with more RAM. It doesn’t spoil game play, but it is something to be aware of if you were to buy the Basic option.

Benchmarks aren’t really a fair way to judge a phone, but they are a useful tool and give us some solid number to look at.

In Antutu version 3.4 the Neo N003 basic manages a benchmark score of 13,323.

Vellamo scores are as follows. HTML5: 1544. Metal: 488.

While running these benchmarks or playing games a little heat is generated on the rear of the Neo N003 just below the left hand side of the rear facing camera. The increase in temperature is especially notable when gaming or running benchmarks such as Epic Citadel, speaking of which the N003 managed an average FPS of 45.7.

Nenamark 2 FPS benchmark gave at top score of 34.1fps.

Finally, we ran 3D mark for you gamers out there who might be considering the an N003 Basic. For Ice Storm Extreme the Neo managed 1847 where as the regular Ice Storm test it faired better with a benchmark of 3597.

In a nut shell the Neo N003 Basic is fine for most users, but if you hate lag and want faster app loading you would be wise to spend the extra on the 2GB RAM Advanced version.

Camera quality – Great photos, great video!

Most of the current crop of Chinese MT6589T phones offer very similar hardware, the Neo N003 is no different and has a 13 mega-pixel rear camera but only a 3 mega-pixel front. For us 3 mega-pixel is more than enough for Skype video calls, and as we don’t take any self portraits it is more than enough camera.

The rear camera is what I was most interested in, would it be able to capture great photos at a seconds notice? Would clarity and focus be an issue? Would the images appear washed out with too much white balance?

Below is a selection of photos taken with the N003 on bright sunny days and also during the night. As usual you can download full size untouched images here.

I’m an really happy with the image quality the Neo manages to record. Colours look great, clarity is perfect and focus is spot on.

Earlier this year I took the UMi X2 and JiaYu G4 for a camera shootout at the Qingdao Auto-show, had the N003 been available at the same time it would have been easily my go to device and a clear winner.

Not only does the Neo get great photos it also manages to focus quickly and capture and save the image in no time. Even taking photos of my children riding their scooters at speed the Neo performed better than I expected!

Low light images are also handled well, but the N003 isn’t a phone you would want to use to capture photos of you and your friends hitting up the bars at night. Night or dark in door photos are noisy, and the LED flash is pretty useless unless you only want the very center of the image to by seen.

So overall taking photos (as long as it isn’t too dark) is a great experience with the Neo N003, but how about video? Again the UMi X2 and JiaYu G4 suffered from the focus which continually adjusted and hunted making any video captured terrible to watch and unusable. So what about video on the N003?

The video above was captured on the phones highest resolution (1920 x 1080) on with and recorded on a sunny day, and as you can see the video is really rather good! In fact I will go as far to say the Neo N003 is the current Chinese MTK phone video champ!

Battery Life – Great, even with my bad habits!

If you have read any phone review I have put together you will know by now that I don’t go out of my way to preserve the power in my phone. I constantly have WIFI, GPS and 3G switched on and my email accounts push messages to me as and when they arrive. I also have either QQ or WeChat running in the background too, that plus I’m a heavy web browser a lot of which is handled over 3G.

In fact the only power saving measure I have is that the screen is only on full when outside, I turn it down to around %50 for the rest of the time.

So with that in mind I am happy to report the N003 has pretty impressive battery life, which is not really a surprise after seeing the thickness of that 3000mAh battery which rests in side the belly of the phone!

After a few charges and recharges I was able to get the through the day with juice to spare on the N003, but if you do have better habits than I do you will likely get better results.

On the other hand if you are a gamer, use the GPS for running apps or navigation and like to listen to music with the built from your phone, your mileage is going to vary.

Connectivity – Perfect, expect for the usual GPS bugs.

When you buy an Android smartphone you expect, WIFI, 3G, GPS, Bluetooth etc to work right of the box. Well the Neo N003 get’s 3 out of the 4 right. As usual with a Mediatek powered phone the GPS was extremely slow to lock on the first time, and not really that quick in following test.

Thankfully there are a few tips, one of which was published by Eduardo from chúng tôi Using Eduardo Mediatek GPS fix solved the slow GPS with the Neo N003 making it much faster to lock on to your location and it also seemed a more accurate too.

Browsing the web over WIFI and 3G are handled flawlessly, and speed of website rendering is really impressive.

I use China Unicom WCDMA on my phones and I always have a signal no matter where I go, but this is due to the number of antennas there are in China (on a recent trip to the UK I noticed how much better the Chinese 3G networks actually are!), and call quality is great with no dropped calls.

Speakers – Good

The cool looking external rear speaker on the rear of the Neo isn’t the loudest we have heard from a Chinese phone, but it is more than enough to make a nuisance of yourself if you were to play games on a bus without earbuds.

Clarity is about right phone a phone of this price. It isn’t as clear and nice to listen to as say a Meizu phone, but again it does the job.

Conclusion – The most feature packed and polished MTK phone to date!

The Neo N003 is a feature packed phone, OTG, MHL, 1080 display, quad-core processor, 13 mega-pixel camera etc, and rather than just plugging in all the best features and selling the phone, Neo have actually taken the time to develop it in to easily one of the better performing and easy to live with Mediatek phones of the year!

Update: It is a shame we weren’t sent the 2GB RAM version of the Neo N003 so we could see what this phone is really capable of,  but if you can live with the short lag , the lag issue can be fixed by installing an alternate launcher such as Nova Launcher,  and don’t mind the slower app loading times you could just about get away with the basic if you had to get a phone now, if you can spend a little extra then I would go for the 2GB model.

We tested the N003 over a week and used it as our main phone the only issue we had was the slow GPS (which we fixed) and one odd time the phone decided to just turn off (something which we have been unable to replicate). As Chinese Mediatek phones go I will say that this is the best to date, in fact the only thing which would stop me from buying the N003 is the fact I don’t like the design, and I would want the Advanced version.

But, with the Neo launched so late is this phone still worth buying? According to insider news 8-core phones could be on sale as early as January, so we should skip the N003 and buy one of those right? I would say no. The first batch of quad-core phones this year were a little buggy, all plagued with delays and all received processor updates in a matter of months, what’s to say the same won’t happen next year?

The Neo N003 might be one of the latest phones to launch this year, but it is also the most enjoyable. If you choose to go for the 2GB Neo N003 as your phone it should be more than enough device, with all the functions you could want to last you until the sorted 8-core Mediatek phones launch around this time next year!

To answer the question “Has it been worth the wait?”, the answer is “Most definitely yes!”.

Thanks to chúng tôi who lent us this Neo N003 Basic for review.

Protect Your Eyes From Your Phone’s Screen With The Cf.lumen App By Chainfire

The booming smartphone’s market has made the mobile manufacturers to improve their device’s performance and the appearance. The android world is now comprised of phablets with a huge screen and a bright display to attract the customers. Moreover other designs including the handy android devices to the huge android tablets have attractive screens to occupy the minds of people with their elegance. Most people use their android devices for prolonged hours which ultimately hurt their precious eyes. Are you a victim of your android device’s bright displays too? Then here is a best solution to soothe your eyes with this little app- CF.lumen.

The popular android developer Chainfire who has developed many android apps and exploit scripts, has once again got our attention with his latest app submission in the android market named CF.lumen which runs on rooted kitkat devices. The new app is intended to protect your eyes from your phone’s display by modulating your phone’s display automatically according to the external conditions.

CF.lumen adapts the colors on your Android device based on the position of the sun, or your custom configuration. When using the default settings, your display will get a warmer tint (lower color temperature) when the sun is down, vastly reducing strain on the eyes. This will take some getting used to, though! The colors also match closer to common artificial light sources, than the daytime light you get from the sun. Blue light makes your brain want to stay awake, and a lower color temperatures reduces the amount of blue displayed. Using this in the evening also reduces your brain’s effort to keep you awake at night, and can be beneficial to your sleeping pattern. During sleeping hours by default a red filter is used. Red strains your eyes the least, and retains your night vision.

The app also uses the ambient light sensor on your device to detect the lighting conditions in your surrounding and adjust the device’s brightness accordingly. There are many colour filters available in the app like red, green, blue, amber, salmon and also an option to adjust the filter manually to suit your comfort. The enhanced image processing techniques used in this app preserves the detail in the screen by converting them to gray-scale before converting them to your selected filter.

The one noteworthy feature of this app is that it includes the colour adjustment settings for the people suffering from colour blindness. The master color filter setting also has an option for color blindness enhancement, with settings for protanopia/anomaly, deuteranopia/anomaly and tritanopia/anomaly. These options redistribute colours across the spectrum, in theory enhancing clarity and colour detail.

The app also comes in Pro version which includes unlock the option to start at device boot and unlock notification options. In Pro mode, the notification adds convenient buttons to quickly disable the current filter or switch to sleep mode, and you can switch the notification to when enabled mode, which shows the notification only when a colour filter is active.
