Blackr

Turn your screen black while apps keep running

Blackr is a clever utility designed for anyone who streams video, records long clips, listens to music, or reads at night and wants the screen effectively off without interrupting what’s running underneath. Instead of actually powering down the display, it overlays a pure black screen, which is especially efficient on OLED and AMOLED panels where black pixels are physically switched off.

The interface is minimalist but thoughtfully designed. You can trigger Blackr from a persistent notification, a floating icon, or quick tiles, making it easy to enable it in the middle of a video or background app. Once active, you can choose between a completely black screen or a subtle always-on-style layout that shows time, date, and battery level. A motion clock gently shifts position to reduce burn-in risk, and you can disable it entirely for maximum darkness and privacy.

Blackr’s advanced options are where it really stands out. QUICK LAUNCH lets you jump directly into your favorite streaming or media apps with a tap, then immediately dim them behind Blackr’s overlay. There’s also an RGB LIGHTING mode that cycles smoothly through colors, turning your device into an ambient light source or simple mood lamp.

Performance is excellent: the overlay is responsive, battery usage is minimal, and the absence of ads or tracking gives it a clean, trustworthy feel. The app doesn’t request internet access and keeps permissions to the bare essentials, which will appeal to privacy-conscious users.

Blackr is not a full replacement for a system lock screen, but as a tool for saving power, reducing eye strain, and keeping content running discreetly, it’s polished, reliable, and surprisingly versatile.
