Introducing Blackr: The Ultimate Screen Off Solution

Blackr simulates a screen off state over apps while allowing them to continue running. This feature is particularly useful for various scenarios such as:



  • Streaming videos

  • Camera recording

  • And many other use cases

Design and Compatibility


The app boasts a simple and smart design, making it incredibly easy and convenient to use. It works best with OLED and AMOLED displays, as these technologies switch off any pixel displaying true black.

Versatile Usage


Blackr can also function as a:



  • A pure black screen app

  • An always-on display (AOD)

  • A simulated lock screen

User Privacy and Efficiency


This app contains NO ADS and requires minimal permissions—no internet access is requested. It is designed with user privacy and optimal battery usage in mind.

Features of Blackr



  • Use notifications, widgets, or a floating icon to start the app.

  • Full black screen support everywhere.

  • Keep apps running while the screen is essentially off.

  • Supports quick tiles in the notification bar.

  • Highly customizable intuitive design.

  • Clock toggle for pure black screen functionality.

  • Motion clock to prevent screen burn-in.

  • Display date, time, and battery (optional).

  • Prevent device from sleeping (if necessary).

  • Small app size and extremely efficient design.

Advanced Customization


Blackr also offers advanced features such as:



  • Fixed icon position

  • Modern icon design

  • Unlock button to prevent accidental unlock

  • Screen opacity control


These features make the app super customizable to fit your needs.

Quick Launch and Unlock Style


The Quick Launch feature allows you to launch chosen apps with a simple tap or press, making it convenient to use your favorite apps such as:



  • YouTube

  • Netflix

  • Prime Video

  • Disney+

  • And many more!


The Unlock Style feature enables advanced gestures to disable black screen mode, preventing accidental unlocks. You can choose from swipe gestures or up to four taps to unlock, a feature that was added based on popular demand.

RGB Lighting and Symmetrical Clock


Experience stunning RGB lighting that fades through different hues, adding a modern aesthetic to your device. The Symmetrical Clock moves only along the vertical axis, ensuring perfect symmetry while avoiding burn-in, thus prolonging the life of your screen.

Easy Integration


For added convenience, you can add a Blackr button in the quick tile settings in your device's status bar (near Wi-Fi, Bluetooth, etc.). It works seamlessly at any time!

How It Works


Blackr operates by displaying a black overlay on top of the screen. On most modern displays, black pixels are turned completely off, effectively turning the display off. While your phone is not sleeping, power reduction comes mainly from reduced screen usage, which is beneficial in preventing screen burn-in.

Optimal Performance


Blackr works best on OLED screens, including:



  • AMOLED

  • PMOLED

  • QD-OLED

  • And similar display technologies


However, the app will still function on any display type.

Device Compatibility


The app runs optimally on devices such as:



  • Google Pixel

  • Samsung Galaxy

  • Samsung Fold and Flip

  • OnePlus

  • And more


Any device with an OLED display will work great and as intended.

Use Cases


Blackr can be utilized in numerous scenarios, including:



  • Recording long videos

  • Watching YouTube, Netflix, or Prime Video with the screen off

  • Streaming videos while listening to music


Moreover, users find it quite useful for keeping the screen on or off manually, rather than relying on the lock button during frequent use. The application is versatile and can be used in countless scenarios.
