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

Just want to give a big "Thank You!" for this app. You have turned my daily commute into study time using Anki. I installed your app, and paired it with a bluetooth media button. I really like how you have check marks at the top of the app showing what permissions have been granted (or enabled) and which haven't been given. Anki has keyboard shortcuts I mapped using your app.Initially, I had go into the app settings and switch to Key Mapper Keyboard each time I connected the bluetooth media button. I figured out using your help instructions how to grant permission to Keyboard/Button Mapper to automatically switch to the Key Mapper Keyboard.

Needed it for something really simple, ended up having fun just messing around with its capabilities lol. Like Tasker but friendlier. Very versatile and has a wonderful guided UI/UX, but I see how some reviewers got frustrated. You definitely need at least a very basic level of tech literacy to understand what you're doing. It does have very clear step by step instructions though, so if you're not familiar with this please just don't skip em and I promise you'll be alright. Props to the devs! ✨

it worked really well in the beginning, but then after updating my OS, upon connecting a controller and after granting accessiblity permissions it starts causing a delay on the controller buttons after one minute. turning off the accessibility permission fixes it. I would really like to give a 5 star rating because otherwise it works really well.
