Where Flashlight and Simple Flashlight keep to a single torch, Lumolight pairs the camera LED with a screen light in one app. It is free, has no ads, and is listed in our flashlight category. Google Play shows a 4.2 rating from 132 ratings and over 50 thousand installs.
BitMavrick's open-source GPL project
Lumolight is built by BitMavrick, who keeps a project site at bitmavrick-lumolight.github.io. The source is public on GitHub under the GPL-3.0-only licence, so anyone can read how the LED torch, the blink timing and the colored screen light are handled. The app first appeared on June 22, 2025, and version 5.1.0.35 was updated on September 15, 2026.
LED blinking, strength control and a colored screen light
The LED side covers a steady beam, an adjustable duration and a blinking mode. Blink speed is set in BPM. Flash strength control exists, but only on supported devices, so not every phone will show it.
The screen mode turns the display into a white or colored light with adjustable brightness. The developer describes it for reading at night, soft bedside light and cases where the camera flash does not suit.
Android 13 minimum and a 5.7 MB file
The app needs Android 13 or newer, which rules out older phones. The package is small at 5.7 MB, and the package ID is com.bitmavrick.lumolight. Google Play rates the content as Everyone, and the app is free.
