Use your Android phone as a wireless Bluetooth mouse trackpad and keyboard for your PC. No server, no drivers, no app needed on the PC side — your phone connects directly as a standard Bluetooth HID device.
Built for the couch, the bed, or anywhere you want to control your PC without reaching for a physical keyboard and mouse.

- Bluetooth HID — Connects directly to your PC as a standard keyboard and mouse. No companion app or server needed on the PC.
- Trackpad — Single finger drag to move the mouse. Tap to left-click. Two-finger tap to right-click. Two-finger drag to scroll.
- Compact Keyboard — Full QWERTY layout with numbers, symbols, modifiers (Shift, Ctrl, Alt, Win), arrow keys, Esc, Tab, Enter, Backspace, and Delete.
- Dedicated Mouse Buttons — Left and right click buttons at the bottom of the trackpad. Hold left click and drag on the trackpad to move windows.
- Click-and-Drag — Button state is preserved during mouse movement, so dragging windows and selecting text works properly.
- Fullscreen Keyboard — Toggle button to expand the keyboard to full screen for easier typing, then switch back to split view.
- Sticky Modifiers — Tap Ctrl, then tap a key for combos like Ctrl+C. Tap Win alone to open the Start menu.
- Auto-Reconnect — Remembers your last connected device and reconnects automatically when you reopen the app.
- Dark Theme — Easy on the eyes for use in low-light environments.
- Idle Wake-Up — Sends a wake-up pulse after inactivity so the first input after idle isn't delayed by Bluetooth sniff mode.
- Optimized Input — Mouse reports are throttled and sent on a dedicated background thread to minimize lag and keep the UI responsive.
- Android 9+ (API 28) — required for the Bluetooth HID Device API
- A PC with Bluetooth that supports HID input devices (most do)
