+# Spring 2026 Developer Contest
+This app was entered in the Spring 2026 Developer Contest on the official Pebble appstore.
+
+I set out to make a unique app that isn't just "for" Pebble, but _needs_ Pebble. This app uses:
+- Pebble health (sleep data)
+- The timeline (history tracking)
+- PKJS (API calls)
+- Vector animations (it's gotta look cute, right?)
+- Crazy good battery life (kinda hard to track sleep when your watch needs to charge)
