Dotori Bluetooth Keyboard

Dotori Bluetooth Keyboard turns your Android phone into a Bluetooth HID keyboard and trackpad for a nearby PC, tablet, TV, or set-top box.

Your phone pairs as a standard Bluetooth keyboard and mouse, so the host needs no driver, no companion app, and no account. Once a host completes the connection and the first keyboard report, it is saved as a verified host you can come back to.

Key features:

- Custom on-screen keyboard for portrait and landscape

- Sentence input mode: compose with your usual system keyboard, check the line, then send it with Space, Enter, or the Send button

- Voice input on Android 12 (API 31) or later: speak a sentence and the recognized text is sent to the host over Bluetooth. It uses only your phone's on-device speech recognition, so your voice is not sent to an online service

- Korean/English switching with a Korean 2-set layout

- Long-press the Korean/English key to realign the on-screen indicator with the host - the long press does not send a key

- Input profiles for Windows Korean 2-set, Windows US, iOS US, and Android TV US

- Input calibration that sends a Korean or English probe, so you can confirm what the host actually received before you rely on it

- Trackpad with pointer sensitivity, natural scrolling, left and right click, and vertical and horizontal wheel lines

- Verified host history with filtering and sorting

- Compatibility diagnostics: a passive preflight that only observes state, and a guided active test where each action runs only after you approve it

- Diagnostic export that leaves out Bluetooth addresses, host names, and typed text

- Safe session handling that blocks input and tells you what to do when the Bluetooth state cannot be confirmed

- Korean and English UI with accessibility labels throughout

What you type is delivered over Bluetooth HID to the host you selected. It is not sent to the developer, and it is not sent to the ads SDK. The app has no login and no developer backend.

What works depends on both sides: your phone must expose the Bluetooth HID Device profile, and some hosts restrict certain keys or horizontal scrolling. The built-in diagnostics let you check your own combination instead of guessing.

This version uses the Google Mobile Ads SDK to show a banner on app screens. The banner is not attached while a connection is being established, while the session is recovering, or while the session is quarantined.
