Description
Blue Light Filter overlays a translucent filter on your screen to cut blue light. It helps ease eye strain and tired eyes, and at night it gently dims the screen with a warm tint to support better sleep. Enjoy a screen that's easy on your eyes all day long.
The blue light from phone and tablet LED screens is said to affect eye comfort and sleep quality. With this app you can cut blue light in a single tap. The filter color and strength are fully adjustable, so even a too-bright screen at night becomes comfortably soft.

[Features]
►Filter settings Freely adjust the filter color and strength to suit your eyes.
►Quick control from the notification bar Turn the filter on/off or change its strength in one tap from the notification bar. You can also choose to hide the notification.
►Per-app filter settings Automate the filter on/off for each app. The filter you set kicks in when you open the target app, and reverts when you close it.
►Timer settings Automatically turn the filter on/off every day at the times you set. The blue light cut kicks in automatically when night comes.
►Widget & Quick Settings tile Toggle the filter in one tap from a home-screen widget or the Quick Settings panel.
►Simple, easy-to-understand design Just the features you need, intuitively laid out. Easy to use even for first-timers.
This app uses the Accessibility service. It is used to detect which app has started or stopped, so the filter behavior can be switched per app. This information is never stored or shared.
[For HUAWEI device users] Some HUAWEI devices are set by default not to auto-restart apps after a reboot. In that case, please set the following: Device Settings → Battery → App launch → set the app you want to auto-start to "Manage manually".
[For OPPO device users] This app needs to run a background service that detects which app has started. Due to OPPO's unique behavior, special settings are required to keep an app's service running in the background. (Without them, the background service is force-stopped and the app won't work properly.) In the recent-apps list, drag this app down a little to lock it. If you're not sure how, search for "OPPO task lock".
Recent changes: Improvements & bug fixes
• Fixed an issue where per-app auto on/off could misdetect the foreground app and switch the filter unexpectedly • Improved stability (crash and ANR fixes) • Fixed other minor bugs

After trying a lot of filters finally agreed to settle on this one Lightest, fastest and no ads. Does the job with all preferences of choosing the color presets

Decent app, but didn't indicate that it needed to be upgraded to a pro version. Just indicating 'in-app purchases' isn't enough. There wasn't any warning, it just stopped working. I have purchased another pro filter because of it.

Where have you been all my life????.. I've been looking for a suitable light filter that autostarts and doesn't get killed underground.... And I finally found one

It works good, but I encountered one problem. Even if the app is off it prevents from adding new cards to Android Pay. Had to remove it for the time of adding cards.

Remember this app is not free as it seems to be because after random time it will show you, "expiration date of trial has passed." Used only 2 times and after a week I decided to use it again but sees this message. Thanks. Vi would have purchased if you asked or made it optional but since it was forced and I can't use the app anymore, I'm looking for alternative. 💩💩💩💩💩 - 5 for you.

Blue light filter will not open because I refused to buy the pro vision. I would really like to tell you where to put it. 🤣😂🤣
