Jaan
A cross-platform mindfulness app delivering guided meditation, sleep sounds, and personalised daily practices — built natively for Android and Flutter.
Overview
Jaan required a seamless experience across Android (Kotlin) and a shared Flutter UI layer, all backed by a Firebase real-time database. The core challenge was keeping session-state, audio playback, and offline content in perfect sync across both surfaces while maintaining a calm, distraction-free UI that reflects the app's mindfulness ethos.
