## Description

**Key Mapper & Floating Buttons** lets you remap phone buttons, keyboards, gamepads, mouse buttons, headsets, headphones, and fingerprint sensors. Create custom shortcuts, multi-step macros, screen gestures, keyboard inputs, media controls, app launches, and floating on-screen buttons for use in any app.

Configure long-press, double-press, repeated, or combined key triggers, then apply constraints based on the active app, media playback, or lock screen. The open-source app uses Android Accessibility services to detect key presses and display assistive overlays. It does not collect user data or send data over the internet.

## Review summary

Users praise Key Mapper & Floating Buttons for powerful input remapping (notably mouse side button mapping for games) and the convenient floating button. It is viewed as a top, feature-rich tool with a loyal user base. However, common complaints include stability problems (crashes/lag), updates that break functionality or reset permissions, and concerns about the paid floating-button model. Additional issues include a visibility bug and various input limitations (headphone jack inputs, controller-as-mouse support).

### Pros

- Powerful input remapping and macros, especially remapping mouse side buttons for games
- Floating button feature is popular and useful, with potential on/off toggle and customization
- Overall very positive sentiment and strong praise; app considered among the best by many users
- Works on some devices with compatible hardware (e.g., RedMagic 11 Pro) and external triggers
- Long-standing development with a dedicated user base and extensive feature set

### Cons

- Stability issues: crashes and lag on devices
- Updates can break functionality and permissions do not persist
- Floating button is a paid feature, which dissatisfies some users
- Floating button visibility bug: 0 opacity does not hide the button
- Input limitations and hardware compatibility: cannot disable headphone jack inputs and cannot use a controller as a mouse pointer; only records buttons
