Billy 0.5

Billy is a Gemini assistant for Pebble watches. Ask by voice; Billy answers with short text and Pebble-style cards, and with the Android companion it can act on your phone and Google account.

Install

• Watch app (iPhone or Android): open Billy-0.5.pbw on your phone and install it with the Pebble app, then paste your Gemini API key (from https://aistudio.google.com/app/apikey) in Billy's settings.
• Billy Companion (Android, optional): install BillyCompanion-0.5.apk and follow the four setup steps in the app. It installs over earlier Billy Companion builds.

What's new in 0.5

• More watches: Pebble Time, Time Steel, Time Round, Pebble 2, Pebble 2 Duo and Pebble Round 2, as well as Pebble Time 2, including layouts for round screens.
• Your own Gemini account (experimental): link it in Billy Companion to find photos in your Google Photos library and use what Gemini knows about you. If it stops working, Billy uses its normal tools.
• Read before you send: texts, replies and emails can be read in full on the watch before you confirm.
• More reliable: answers can't get lost or land in the wrong chat, a repeated message can't run an action twice, and reminders only say "set" once Pebble's timeline confirms them.
• Phone-only mode starts even when Pebble's timeline sign-in fails.

Notes

• You pay Google for your own Gemini usage; Billy has no server.
• The Android app is signed with the same key as earlier test builds, so Google sign-in keeps working.

Billy 0.1 is the first public release of the Billy Pebble assistant fork.

Highlights:

• Renamed and re-identified the Pebble app as Billy with its own UUID, 0.1 version label, and updated goat iconography.
• Added a companionless Gemini runtime so the PBW can work without a hosted helper server.
• Added the optional Billy Android Companion for phone-side Gemini, Google account tools, media transfer, weather, maps, Calendar, Gmail, Tasks, Drive, Docs, Sheets, Slides, and related API paths.
• Added user-owned Gemini and optional Maps API key setup flows; no developer API key is bundled.
• Preserved Bobby-style Pebble features such as alarms, timers, reminders, sample prompts, settings, feedback, quota display, weather cards, and Pebble-native chat presentation.
• Added README and setup documentation for users and future contributors.

Release assets:

• Billy-0.1.pbw: Pebble watch app.
• BillyCompanion-0.1-debug.apk: debug Android companion build for side-loading during early distribution.
