PebbleRecorder

Use your Pebble watch as a remote start/stop button for audio recording on your phone. Press a button on the watch and a companion Android app records straight to a folder you choose — no need to touch your phone.

How it works

Two apps:

• watch/ — a Pebble watchapp (C). An Idle → Recording → Paused state machine with a status icon and a live timer. It has no microphone logic; it just sends start/stop/pause and shows whatever status comes back.
• android/ — a native Android app (Kotlin) that does the recording (MediaRecorder, AAC/M4A), with optional Gemini transcription to a sibling -txt.md file.

They don't talk directly. Messages go over Pebble's AppMessage protocol, relayed by the Pebble/Core companion app:

watch app  ◀─AppMessage─▶  Pebble/Core companion app  ◀─AIDL─▶  android app

Pebble's SDK has never exposed raw microphone access to watchapps, so all recording lives on the phone and the watch is just a button.

Requirements

• A Pebble watch with a phone running a PebbleKit-2 companion app (e.g. Core Devices' app).
• Android 8.0 (API 26) or newer.

Build

Watch (watch/) — needs the Pebble SDK

cd watch
pebble build
pebble install --emulator basalt      # or: --phone <phone-ip>

Android (android/)

cd android
./gradlew :app:assembleGithubDebug

Install the APK and grant microphone access. Recordings default to Downloads/PebbleRecorder; pick another folder in the app if you like. It then runs quietly in the background, armed for the watch trigger.

A real end-to-end test needs both apps plus the companion app and a paired watch — no emulator can exercise the full loop alone. CLAUDE.md has the protocol details, the foreground-service model, and the release checklist.
