Pocket KBM: Bluetooth Keyboard

A dead keyboard, a flat mouse, or peripherals left at home — Pocket KBM turns the phone already in your hand into a Bluetooth keyboard, a Bluetooth mouse and a gamepad for your computer — and a presentation remote when you need one.

Nothing is installed on the computer: no software, no driver. Your phone needs no root. It connects as a standard Bluetooth HID peripheral, so the computer pairs with it the way it would pair with any Bluetooth keyboard. Everything works offline, with no account.

■ Check that it works before you pay

Bluetooth compatibility cannot be promised for every computer, so connecting, the trackpad, the full keyboard (numpad included) and the gamepad are **free forever**. Try your own computer first, then decide.

■ Free

• Connect and pair — from the computer, or reconnect a paired one
• Trackpad — a wireless mouse and touchpad: move, click, two-finger scroll, two-finger right click, drag
• Full keyboard — latching modifiers, F1–F12, navigation and editing keys, system keys
• Numpad — real keypad scancodes, so spreadsheets and Alt-numeric codes work
• Presenter keys — previous and next slide, start, blank, end: a presentation remote for PowerPoint or Keynote
• Gamepad — buttons, D-pad, two sticks, trigger buttons (LT/RT)
• Vibrate on press — the phone's own haptic feedback
• One custom page — single-step buttons, to see how it feels

■ Premium (one payment, kept forever)

• More custom pages with your own layout — a page is a canvas; place and resize buttons, sticks and pads yourself
• Multi-step macros — key combos, hold and release, delays, all on one button
• Typed text — one tap for a string you type often
• Media keys — playback, volume, tracks, plus browser and brightness keys
• Gamepad rapid fire
• Choose which tabs appear

One payment, tied to your Google account, so a new phone or a reinstall costs nothing more. No subscription. No ads.
Buying and restoring are handled by the Google Play Store, which needs a connection at that moment; using the app as a keyboard and mouse never does.

■ Please know these limits first

• Not every Android phone can act as a Bluetooth peripheral. It depends on whether the phone's firmware offers the HID Device role; phones without it say so plainly, and the app falls back to Bluetooth LE.
• The gamepad enumerates as a DirectInput controller. Games that only support XInput — many modern PC titles — will not see it, and the Nintendo Switch almost certainly will not.
• Keys are sent as standard US layout positions. Chinese, Japanese and emoji have no HID scancode and rely on the computer's own input method.
• A battery percentage can only appear over Bluetooth LE. Over Classic Bluetooth neither Windows nor macOS has any way to show it.
• Bluetooth latency is fine for typing, office work and casual use, but not for competitive gaming.

■ Privacy

No account, no ads, no analytics, no backend. The app holds **no internet permission at all** — what you type cannot be sent to us or to any online service. Macro contents stay out of cloud backup.

■ Before you connect

Only pair with a computer you own or have permission to control. While connected, every key, click and macro is delivered to that computer immediately.
