Apr 1, 2026April 2026 monthly summary for lichess-org/mobile highlighting key features delivered, major bugs fixed, impact, and skills demonstrated. Highlights include lifecycle-aware state management for Kid Mode (WidgetsBindingObserver to refresh account state on resume and ensure kid mode interactions update the account drawer and preferences when returning to foreground); Daily Puzzle Widget for iOS with a new widget, improved iPad layout, startup theme synchronization, and deep-linking to the daily puzzle screen; Blog Feed Widget visual polish for readability (font sizes and baseline alignment); Core Chess Gameplay Improvements enabling starting games from a custom FEN position and adding a resign option in the bottom bar; and Puzzle Themes Search for easier navigation. Major bugs fixed and polish: - Widget content is disabled when Kid Mode is active to avoid conflicting UI and data refresh issues. - Puzzle widget layout has been fixed for iPad to improve consistency across devices. - On startup, puzzle themes and widget themes now synchronize reliably, reducing first-run inconsistency. Overall impact and business value: - Improved user experience and engagement through reliable, lifecycle-aware features and polished UI widgets. - Enhanced offline/online gameplay flow with FEN-based starts and faster puzzle theme navigation. - Reduced unnecessary network activity and improved consistency across iOS widgets, leading to better retention and satisfaction. Technologies/skills demonstrated: - Flutter/Dart lifecycle management with WidgetsBindingObserver; iOS widget development; deep linking; app group/theme synchronization; UI layout tuning; and code quality improvements (4-space indentation in iOS).

Mar 1, 2026Month: 2026-03 — lichess-org/mobile delivered a set of user-facing feature enhancements, reliability improvements, and UI polish that collectively raise engagement and support post-release diagnostics. Highlights include aligning Puzzle Dashboard analytics with the web experience, enriching Variant Picker UX, and introducing a clock-low-time animation. Reliability and observability were strengthened by persisting app logs for later analysis with TTL and pagination, complemented by UX improvements such as Pull to Refresh on the User screen. These changes reduce user friction, accelerate decision-making in play, and improve maintainability through refactors and clearer code quality efforts.
