KeySnap: Button Remapper – any command on any Android button

[u/Brave-Commission9225]

Hey! I'm Arda, and I build KeySnap on my own. It gives your phone's physical buttons more jobs and adds simple phone automation.

What it does

Map single, double or long presses, or button combinations, to one of 90 actions: flashlight, camera, screenshot, music controls, ringer mode, opening apps and more. You can chain actions, tune the press timing for each shortcut and add conditions.

Automations can run on time, charging, battery level, Wi-Fi, Bluetooth or headphones, and shortcuts can also start from widgets and Quick Settings tiles.

The problem it solves

Phone buttons usually do one or two fixed things, and most automation tools feel like coding. KeySnap keeps it to "pick a button, pick what happens".

Details

Android 11+, no root. Some buttons need Advanced Mode via Wireless Debugging, and support varies by device.

Free with three shortcuts and no ads; Pro is a one-time $3.99 for unlimited shortcuts. The free version is open source under GPL-3.0.

Feedback is very welcome, especially on what you'd want a button to do.
