Blackr Reboot - Due to popular user demand the app is live again!
Please uninstall and re-install to avoid any issues.

Blackr simulates a locked screen like state over any app, and does not stop them from running. Like watching a video on YouTube or recording a video for a long time, so many use cases!

Simple and smart design makes it very easy and convenient to use.

Please note - Since Android 8.0 (Oreo) or higher, navigation and status bar can't be hidden completely due to OS security reasons. But if an app is full-screen it will work fully.

This is NOT a lockscreen app but an overlay app, on OLED screens this is like turning the screen off but the phone isn't in sleep mode.

Best way to use the app is, add a blackr button in the quick settings in device status bar. It works seamlessly any time!

App Feature List:
- Keeps app running and screen essentially off.
- Run app using notification or floating icon.
- Supports quick tiles in in notification bar.
- Highly customisable design.
- View date, time, and battery percentage.
- Motion clock to prevent burn in or can be turned off completely.
- Optionally disable device from sleeping.
- If enabled, auto restart after device reboot.
- Very small app size and extremely efficient app.

Runs great on devices like Google Pixel, Samsung Galaxy, Note, OnePlus and more.
It works by showing a black overlay on top of the screen and on modern AMOLED displays this turns off all pixels, effectively turning the screen off.

Please note this is NOT a lockscreen app, It is an overlay, and your phone is not sleeping while this is on. So power reduction is mostly from less screen usage, and helpful to prevent screen burn in.

Primarily developed for turning screen on easily while developing apps, this app can be used in many scenarios like recording long videos, watching YouTube , streaming videos for playing music, etc.
