Highlights
- Breathing sessions are structured as a full ritual, not just an inhale-exhale loop, with dedicated phases for breathing, retention, recovery, meditation, and session end.
- Recent updates expanded the product beyond the phone with Apple Watch session support, widget surfaces, more precise haptics, and clearer guidance controls.
- Users can review progress through charts, streaks, and session history instead of relying only on motivation and memory.

Technical Notes
- SwiftUI app with a paired watchOS experience, using WatchConnectivity and HealthKit workout mirroring to keep phone and watch in sync during sessions.
- HealthKit integration supports mindful-session syncing and heart-rate aware experiences, while SwiftData stores settings, sessions, and streak-related progress.
- Swift Charts power the stats layer, and WhatsNewKit is used to communicate product updates inside the app after each release.
