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.

This was a great app. I use it to map the buttons of my joycon controller to shortcuts used for Clip studio paint. But with their recent update to allow d-pad mapping, or something, they broke something else. Now my R1 button doesn't perform the action I have it programmed to, (though the press is detected), except, It will sometimes randomly press the key while I have the liquify tool open and make it behave in ways I don't expect and mess me up. I wish they would've just left it alone.

I wanted a quicker way to enable flashlight. I was able to map holding the volume down button and pressing volume up to toggle my flashlight on/off. I've also mapped a quick press sequence of vol down, vol down, vol up to play/pause media. After first creating these, the volume buttons stopped working normally as volume buttons (bad). To fix, I had to go into the profile and add the option of "do not remap" on each of the buttons, and now everything works as it should. Thanks team!

One of the best remapping tools I've used, and my personal favorite. Shizuku compatible and easily integrated with Tasker via shortcuts and intents. Ordinarily, I'd rate ★★★★☆ for an app like this, because I reserve 5 star ratings for apps which I have no complaints about. Key Mapper gets 5 from me because, despite all the excellent features, it's 100% free. REALLY free. No restrictions or limitations you have to pay to get rid of, no ads and, most importantly, absolutely no data collected. 🏆
