9 Best Blue Light Filter App in 2019

Most of us like reading articles on our phones or browse through social media sometime going through walls of text. Some users may notice strain upon excessive use of your phone display, especially during bed time. This is due to the blue light emitted by your phone display. One good remedy for this is a blue light filter. While manufacturers are eager to offer their own version of blue light filters, they’re not widely available on all devices. This is why third party offerings become extremely important. If you own an Android device and experience strain in your eyes after prolonged usage, one of these apps below will certainly help you out.

9 Best Blue Light Filter App in 2019

Twilight: Blue light filter

This app has been around for quite some time now and is considered one of the best solutions to get rid of blue light emitted by your phone which can in turn disturb your circadian rhythm. Unfortunately, Twilight has faced some restrictions after Google made changes to Android with versions 9.0 and above.

However, this doesn’t affect the core functionality of the app, so you’re free to use it as you please. The best part about this app is that it can automatically adjust to the time around you and dim the display depending on that. iPhone owners will be aware of this feature on their devices under the “Night Shift” moniker.

The app is recommend for all screen and display types, including AMOLED panels. Unsurprisingly, it’s also the Editor’s Choice app on the Google Play Store. It is a free app to download and has no ads or in-app purchases.


This app takes inspiration from Flux for desktops which has been widely popular as an automatic blue light filtering solution for those on desktops. EasyEyes works pretty much the same way in theory, allowing you to dim the overall brightness and cut down blue light from the display. The app comes with features like temperature filter along with a comprehensive notifications toolbar to help you quickly access app settings. You can manually set the schedule for sunrise and sunset, thus offering you more flexibility. It is important to schedule this as you can just as easily be staring at a dim screen during broad daylight.

Although this version of the app is free to download, it comes with ads on board. There are no in-app purchases, though. The developers offer a separate premium version of EasyEyes which comes with a few extra features like no ads, the ability to set start and end times for each day of the week, and more. This app works with smartphones running Android 4.0 and above.

Blue Light Filter

This is yet another effective app that does its job perfectly well. It’s a widely popular app as well, so it’s been trusted and used by millions of users around the world. It comes with all the standard features that you would expect, including the ability to quickly dim the brightness and even adjust the intensity of the dimming. The warm light emitted by the app makes reading at night more effective and less straining on the eyes. Furthermore, you are ensured not to lose any sleep if you view content with the blue light filter on.

It has been noted that reducing blue light on your smartphone can greatly reduce battery consumption as well, so it might be a win-win for the users. This is a free app, although there are ads and in-app purchases on board.

This is a slightly better designed app that comes with well laid out controls to give you extensive control over the brightness of your display. It uses a natural color for the filter, which makes reading and typing more comfortable for the users. The app can cleverly detect the external light to adjust the color on your phone display. Naturally, there’s a detailed scheduling feature enabled here as well, allowing you to automate the on/off process.

My favorite feature here is that the blue light filter is for your eyes only. This means that if you take screenshots, those will retain the original color and won’t be dim like your display. To make things even easier for the customers, the company is offering 7 different colors to choose from. It is recommended to make sure this app is launched at device startup. This app is free to download although you’ll have to contend with ads and in-app purchases. The app works with devices running Android 4.1 and up.

Blue Light Filter & Night Mode

The app uses a combination of 5 anti glare bluelight flux filters that reduce strain on your eyes and offer optimum comfort for night-time phone use. Developers recommend using the “Temperature” palette for a cooler tint of your display, which is also an alternative for Night Mode that we see on most phones.

You can also use the scheduling feature to enable the dimming feature at a certain part of the day. This also saves you the trouble of remembering to turn it off each morning. This app is also greatly helpful in reducing the battery consumption of your smartphone for obvious reasons, so there’s no doubt that this is an app you need to have right now. The app is free to download but is supported by ads and in-app purchases. It works with devices running Android 4.1 and above, making it compatible with a wide range of devices out there.

Darker (Screen Filter)

This app is quite similar to several of the apps we’ve talked about here, although the user interface is different albeit more elaborate. It comes with a color filter, helping you pick from a range of colors depending on the display. This gives users an excellent alternative to standard dusky filters which can no doubt encourage sleep early, but are not ideal for night-time reading.

This app is completely free to download and has no ads, but there are in-app purchases. This allows you to unlock certain features that are otherwise absent on this app such as scheduling, the ability to lower brightness below 20%, and adding up to three buttons for quick access to the app’s features. It’s clearly not the perfect blue light filtering app, but it will certainly get the job done.

Blue Light Filter – Screen Dimmer for Eye Care

The developer of this app is known for a wide range of health oriented apps, so you know you’re getting the best here. In terms of features, the app packs a clever user interface with easy to access features, and pretty much everything that you would expect from a blue light filter app. What makes this app stand out, however, is the fact that it also comes with fatigue test, vision test, as well as eye exercises.

You can also choose the ideal color for your screen to keep your eyes safe throughout the day. Metrics like average phone usage and average protect time perfectly illustrate the effects of this app on your quality of sleep. Expectedly, auto power on/off features are also present here. This app is free to download and comes with ads and in-app purchases. The app will work with smartphones and tablets running Android 4.1 and above.

Night Shift

The namesake of Apple’s default blue light filtering feature on iPhones, Night Shift is an excellent solution to bring this much needed feature to your Android device. The developers claim that using this app can save your battery life by about 15%, which is not particularly shocking given that the brightness is expected to be low when the app is in use. As is the case with several other apps mentioned here, users can choose from a variety of colors here.

You will also be able to setup an auto timer that allows the app to turn on and turn off automatically without human intervention. This app can also help if you’ve had a tough and straining day and simply want to do some light reading on your phone. The only side effect is that you can fall sleep early, which I’m hoping a lot of users won’t mind. This app is a free download and comes with ads. There are no in-app purchases on board.

Blue Light Filter Pro

As you’ve probably guessed by the “Pro” moniker, this is a paid app, and the only one on our list. But what justifies the price tag is the fact that you can have extensive controls over the dimming of your phone. For example, you can choose to dim only a particular app (or apps) on your phone and not the entire device.

The developers also offer a widget which allows you to quickly turn the dimming feature on or off in an instant. Further, you also get to control the app through the notifications pane, making this an extremely functional app. Since this app is a paid offering, there are no ads or in-app purchases on board here. Be sure to check it out.
