Month: 2025-08 — Delivered foundational push notification capabilities and extensive UI/architecture polish across the mul-kkam project. Key features include a complete FCM-based push notification system with click-action handling and a notification settings screen, a visually polished Splash Screen with Lottie animations, Health Connect groundwork for data integration, and a revamped Cup Settings flow with item reordering and intake-type/icon displays. A robust logging/observability layer was added (network interceptor, Timber/Crashlytics), improving diagnostics and reliability. Significant data layer and UI/UX refactors (package restructuring, SVG loading, extendable menus) improve maintainability and developer velocity. Overall, these changes drive user engagement, data reliability, and faster feature delivery with cleaner architecture and improved startup performance.
