Add missing physical keyboard layouts to Android.
Lightweight • Offline • No Root • No Permissions • Open Source
Android supports external keyboards, but many useful physical keyboard layouts are missing.
KeymapKit fills that gap by adding system-level physical keyboard layouts such as:
- 🇹🇷 Turkish F
- 🇹🇷 Turkish Q
- and many more in future releases.
Unlike traditional keyboard apps:
- ✅ No on-screen keyboard
- ✅ No IME
- ✅ No root
- ✅ No Accessibility Service
- ✅ No permissions
- ✅ Works completely offline
KeymapKit simply provides additional hardware keyboard layouts that Android can use.
Current screens include:
- Home dashboard
- First-time setup
- Layout Manager
- Typing Test
- Diagnostics
- Material You interface
KeymapKit now installs only the keyboard layouts you actually need.
Choose your preferred layouts during the first launch.
For example:
- Turkish Q
- Turkish F
- English US
- German
- French
Only selected layouts become available inside Android.
Manage installed layouts anytime.
- Add layouts
- Remove layouts
- Search layouts
- View installed layouts
- Update selections instantly
No reinstall required.
KeymapKit automatically recommends layouts based on your current device language.
Examples:
- Turkish device → Turkish Q + Turkish F
- English device → English US
Verify your selected layout immediately.
No third-party app is required.
Built-in diagnostics help verify:
- Physical keyboard detection
- Active layouts
- Provider status
- Connected keyboards
- ✅ System-level physical keyboard layouts
- ✅ Works in every application
- ✅ Dynamic layout installation
- ✅ Layout Manager
- ✅ Typing Test
- ✅ Diagnostics
- ✅ Material 3 / Material You

- ✅ Android 8.0+
- ✅ Lightweight
- ✅ Offline
- ✅ Open Source
Android supports physical keyboard layouts through .kcm (Key Character Map) files.
KeymapKit registers itself as a Keyboard Layout Provider and exposes these layouts directly to Android.
Unlike an IME:
- No text input service
- No keyboard replacement
- No accessibility service
- No background process
Android itself performs all key mapping.
- Install KeymapKit
- Connect a USB or Bluetooth keyboard
- Launch KeymapKit
- Select the layouts you want
- Open:
Settings
→ Physical Keyboard
→ Choose KeymapKit layout
- Open the built-in Typing Test
- Verify everything works
Samsung devices may require tapping the language entry (for example, "Turkish (Türkiye)") before the available layouts become visible.
KeymapKit follows a strict privacy-first philosophy.
It contains:
- No permissions
- No analytics
- No advertising
- No tracking
- No accounts
- No internet communication
- No cloud services
Everything works locally on your device.
