Effortlessly Save Your OLED Screen with Blackr

Elena Angelini

12/20/2024

Blackr by Neximo Labs is a handy app designed to turn off your OLED screen to enhance its lifespan and save battery life, though it may require some fine-tuning to fully meet user expectations.

Blackr is a highly efficient and versatile app that simulates a screen off state without interrupting the functioning of other apps. Its wide range of applications includes turning off the display while streaming videos, recording video with the camera, and many other use cases.

The app features a simple and smart design, which makes it incredibly easy and convenient to use. It is especially optimized for OLED and AMOLED displays that can switch off individual pixels to display true black.

Blackr can also be used as a pure black screen app, an always-on display (AOD), or a simulated lock screen, depending on the user's needs.

One of its key advantages is that it contains no advertisements and requires minimal permissions, not even internet access. The developers have prioritized user privacy and optimal battery usage in the design.

Features:

Keeps apps running with the screen essentially off.
Can be activated through notifications or a floating icon.
Supports quick tiles in the notification bar.
Highly customizable design.
Optional display of date, time, and battery status.
Motion clock feature to prevent screen burn-in.
Clock can be disabled for a pure black screen.
Option to disable device sleeping when necessary.
Small app size with an extremely efficient design.

Advanced Features:

Quick Launch: Allows users to launch their favorite apps with a simple tap or press. Compatible with popular apps like YouTube, Netflix, Prime Video, Disney+, and more.
RGB Lighting: Offers a visually appealing experience by fading through different hues and giving the app a modern aesthetic.
Symmetrical Clock: Ensures that the clock only moves along the vertical axis, maintaining perfect symmetry and minimizing the risk of burn-in, thus extending the screen's lifespan.

An optional way to access the app is by adding a Blackr button in the quick tile settings of the device's status bar, providing seamless accessibility at any time.

The app performs exceptionally well on popular devices such as Google Pixel, Samsung Galaxy, Samsung Fold and Flip, OnePlus, and many others.

Blackr functions by displaying a black overlay on top of the screen. On most modern displays, black pixels are turned off completely, effectively turning off the display. Although it works best on OLED screens like AMOLED, PMOLED, QD-OLED, and similar display technologies that can switch off individual pixels displaying true black, it is still compatible with all displays.

Additionally, Blackr can be used to reduce screen burn-in by changing the lit pixels every minute, acting as a beneficial screen reset. While the app acts as an overlay and prevents your phone from sleeping, power reduction primarily comes from reduced or no screen usage, while also helping to prevent burn-in.

Considering its versatile functionality, Blackr proves to be highly beneficial for various scenarios such as recording long videos, watching YouTube, Netflix, Prime Video, etc. with the screen off, or streaming videos while only listening to music. It is also popular among users who prefer manual control over screen on/off functions rather than using the lock button frequently. Enjoy!
