About this app

Make custom macros on your keyboard or gamepad, make on-screen buttons in any app, and unlock new functionality from your volume buttons!

Key Mapper supports a huge variety of buttons and keys*:

- ALL your phone buttons (volume AND side key)
- Game controllers (D-pad, ABXY, and most others)
- Keyboards
- Headsets and headphones
- Fingerprint sensor

Not enough keys? Design your own on-screen button layouts and remap those just like real keys!


What shortcuts can I make?
--------------------------

With over 100 individual actions, the sky is the limit.
Build complex macros with screen taps and gestures, keyboard inputs, open apps, control media, and even send intents directly to other apps.


How much control do I have?
---------------------------

TRIGGERS: You decide how to trigger a key map. Long press, double press, press as many times as you like! Combine keys on different devices, and even include your on-screen buttons.

ACTIONS: Design specific macros for what you want to do. Combine over 100 actions, and choose the delay between each one. Set repeating actions to automate and speed up slow tasks.

CONSTRAINTS: You choose when key maps should run and when they shouldn't. Only need it in one specific app? Or when media is playing? On your lockscreen? Constrain your key maps for maximum control.

* Most devices are already supported, with new devices being added over time. Let us know if it's not working for you and we can prioritize your device.

Not currently supported:
- Mouse buttons
- Joysticks and triggers (LT,RT) on gamepads


Security and accessibility services
---------------------------

This app includes our Key Mapper Accessibility service that uses the Android Accessibility API to detect the app in focus and adapt key presses to user-defined key maps. It is also used to draw assistive Floating Button overlays on top of other apps.

By accepting to run the accessibility service, the app will monitor key strokes while you're using your device. It will also emulate swipes and pinches if you are using those actions in the app.

It will NOT collect any user data or connect to the internet to send any data anywhere.

Our accessibility service is only triggered by the user when pressing a physical key on their device. It can be turned off any time by the user in the system accessibility settings.

Ratings and reviews

Great app. Has one minor bug which I attempted to inform the developer. However, despite their claims there IS NO METHOD TO REPORT BETA VERSION BUGS. How I even had a beta version is strange as it appears that I am not a registered tester. It's too bad that the developers aren't interested in receiving any feedback.

Thanks so much for this app. My volume button kept going up due to fall messing with the button on the PCB. My phone is already 5 years old. I know repairing this will cause other problems to surface. thankfully you saved me from getting a brand new phone for now. Will use for a few days and get the premium just to show support

It does what it's supposed to to, but using it on a Chromecast is an ordeal. You can't operate the interface with the Chaomecast remote only because it isn't implemented/configured properly. Last time I had to change something (which is rarely the case fortunately), I had to pair a mouse with the Chromecast for literally one single click. Once that's fixed, I'll happily donate a coffee or two ☺️
