Last updated: September 5th

Looking for the PebbleOS changelog?

What should work in the App 🤞

• Works with Core 2 Duo, Pebble Time (Steel/Round) and Pebble 2. Reports of working with OG Pebble + Pebble Steel, but we haven’t tested this ourselves (and would need to be on firmware 3.0+).
• Time sync
• Notifications
  • muting specific apps
  • dismissing notifications on phone from watch
  • (Android only) replying with emoji or canned replies
• Calendar (configure in mobile app, no actions or invites)
• Music control
• Phone calls
• PebbleKit JS apps
• Appstore and locker (via Rebble.io sign in)
• Developer connection (on Watch screen)

What isn’t working or built yet 🤦

• There are intermittent crashes when running PebbleKit JS apps on iOS.
• Mobile app design - it’s basic and works, but is not yet complete. Expect this to change!
• Voice reply processing in the mobile app
• Whatsapp/Signal/etc voice call notifications on Android in the new app
• No health features are supported in the app, yet
• Send Text app
• Alternative language packs cannot be loaded (.pbl files)
• Weather support for default Pebble weather app
• PebbleKit-Android (e.g. Music Boss)
• App Localization
• Ordering of apps in locker
• Calendar invite notifications / Calendar pin actions
• Custom canned responses
• Timeline pins from server (or timeline token generation in PebbleKit JS)

Important

If anything isn’t working, and it isn’t listed below as not working, please report a bug in the app! Try to connect to your watch before reporting, so that the app can fetch watch logs (cycling airplane mode on the watch if required to get it connected). We might not get back to you, but we read every report.

Known issues/bugs

• Bug reporting takes 2-3 minutes sometimes (it’s uploading a ‘coredump’ from your watch)
• Pebble 2 Duo will not keep time if you shut it down. You will need to reconnect it to your phone to get latest time.

What we’d like you to test

Try these things and hit Report a Bug if you run into any problems

• Reliability
  • Notifications should arrive instantly
  • Bluetooth connection should be stable and reconnect if you walk out of range of your phone
• Calendar events - Do they show up correctly in your timeline?
