Pebble going fully open source is a big win for hardware preservation. ⌚️🔓 But for mobile devs, the real story is in the repo.
The new app is a pure KMP + Compose Multiplatform rewrite.
230k lines (Legacy Java/ObjC) ➡️ 37k lines (Kotlin)
Shipped in 6 months with just 2 devs 🔥

Probably my favorite talk at Droidcon London 2026 was @stevepenna.bsky.social on rebuilding Pebble app.
The part that I really liked was the contrasting of the Android development and library ecosystem 11 years ago and today.
It was also nice to see AndroidX appreciation.

Don't ignore this tip! We've switched to using the optimized proguard file & shrinking resources in our latest release and have seen a massive drop in all performance related metrics, with slow app launch metrics dropping >30%. All from a 5 minute code change!

To improve AndroidX release binary transparency we have made all of our release branches visible to the world.
E.g. collections: ci.android.com/builds/branc...
What that means is now you can go from a released version of a library to an exact buildId and the source tree state for that release.
