IndexedDB and cloud sync engine to keep logs consistent across devices.

Backend & Sync Service

Define sync schema

Unit tests, UI tests, and end-to-end verification before App Store release.

Handle and represent sync states to ensure logs remain consistent across devices.

Add functionality to log baby cues (e.g., rooting, crying) before and during feeds.

Design and integrate professional icons and splash screens for both light and dark modes.

Write unit tests to verify WCSession reliably transmits and receives feed updates.

Stream feeding session progress to the Watch in real time, keeping it in sync with the iPhone.

Store feeding logs locally in IndexedDB so the app can work offline and sync changes later.

Ensure the app is fully usable offline, syncing data only when connectivity is available.

Retry failed sync operations automatically to avoid losing feeding log updates.
