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
- Mouse buttons
- 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:
- 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

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. 🏆

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.

I'm speaking on behalf of a friend who played Minecraft with this program. This program will damage your phone and ruin the volume button, just like mine, which turned into powder!!! I really mean my phone turned into powder, its volume button It works, but it's powdered, so you definitely have to use this program wisely and wisely because it may cause damage to the phone that will be difficult to repair.
