FlashDim is a free, open-source flashlight app by Cyb3rko that lets you dim the torch on phones running Android 13 or later. Google Play lists it with a 4.6 rating from 4,753 ratings and over 100 thousand installs. We host the unmodified APK, version 2.5.3, and publish its SHA-256 checksum for verification.
Free, no ads, no purchases
FlashDim costs nothing, shows no ads and sells no in-app purchases. Its content rating is Everyone. According to the developer's description, the app is private and works without an internet connection.
The source code sits on GitHub under the Apache-2.0 licence, so anyone can read it and check how the app handles data.
Brightness levels, SOS and morse flash
Android 13 added control over several flashlight brightness levels, and FlashDim was built to use it. You can dim the light level by level or tap shortcut buttons set to different brightness steps.
Other modes include an SOS flash button, a morse code flash mode and an Interval / BPM mode. A quick settings tile gives fast access from the notification shade.
The design follows Material You (M3) elements, and the app colors adapt to the device's system colors.
Volume-button toggle and the accessibility service
Pressing both volume buttons toggles the flashlight. This is opt-in and is switched on in the settings. It works through the accessibility API, which reads key events from the volume buttons.
The developer states that nothing beyond those key events is collected and points to the GitHub source for verification.
Version 2.5.3 and upkeep
The current version is 2.5.3, last updated on August 30, 2026. The app first appeared on October 29, 2022, so it has been maintained for several years. The package is 2.3 MB.
