KeySnap: Remap Keys & Automate

Give every button on your phone a new job.
Double-tap Volume Down for the flashlight. Hold Volume Up for a screenshot. Double-press Power to open the camera. KeySnap turns the physical buttons you already have into shortcuts for the things you do all day.

WHAT YOU CAN MAP
• Volume, power, camera and assistant buttons
• Headset and Bluetooth headphone buttons
• Keys on Bluetooth keyboards and game controllers
• Extra buttons your manufacturer added, even unlabelled ones
Each key can be a single press, a double press or a long press, and one shortcut can chain several.

90+ ACTIONS
Flashlight, screenshot, open any app, play/pause, next track, volume, brightness, rotation, Do Not Disturb, Wi-Fi, Bluetooth, mobile data, back/home/recents, tap and swipe on screen, type text, shell command, HTTP request, open a URL, and more. Actions run one after another, so a single press can do several things.

ONLY WHEN YOU WANT
Add conditions to any shortcut: time of day, day of week, charging, battery level, Wi-Fi network, Bluetooth device, headphones, dark mode, ringer mode, which app is open, whether music is playing. Or skip the key entirely: an Automation runs by itself the moment its conditions become true.

ADVANCED MODE, NO ROOT
Android hides the power button and many manufacturer buttons from normal apps. Advanced Mode uses your phone's own Wireless Debugging to start a small helper that sees every key and keeps running even when the app is closed in the background. No root, nothing modified, and turning it off removes it.

PRIVATE BY DESIGN
No account. No servers. No analytics. Your shortcuts and your key presses never leave your phone. The accessibility service is limited to the system Settings app and cannot read anything you type or any other app's screen. Open source under GPL-3.

LIGHT, DARK OR SEPIA
Three themes and ten languages.

FREE AND PRO
The free version includes two shortcuts and shows ads. Pro is a one-time purchase that removes both limits. No subscription.

PERMISSIONS
KeySnap asks for a permission only when you use the feature that needs it. Accessibility: to see button presses. Location: only for the "connected to Wi-Fi network" condition, because Android hides the network name otherwise; your position is never read. Bluetooth, Do Not Disturb, usage access and modify settings each unlock one group of actions. Camera is never requested; the flashlight works without it.
Requires Android 11 or newer.
