Bluke lets you use your Android phone as a wireless keyboard, mouse trackpad, game controller, and media remote.

It utilizes your phone's built-in Bluetooth HID profile and acts like how a typical input device would work.

No installing server apps or background clients, just pair, connect and it works.

Features:

Keyboard mode with real mechanical typing sounds (12 built-in switches, custom Mechvibes pack import, Fn media shortcuts, and international layouts).
Trackpad mode with smooth cursor control, natural two-finger scrolling, tap-and-drag, and an LED numpad overlay.
Gamepad mode with dual analog sticks, Xbox/PS5 button styles, stick inversion, and Native/Web/Android controller profiles.
Multimedia remote mode for media playback and slideshow presentations, with optional phone volume rocker control.
Stays connected in the background and with the screen locked while in use.
Material You dynamic themes, custom color palettes, adjustable haptic feedback, and auto-reconnect on launch.
