More resilient GPS uploads: Fixes are saved to a durable local queue, retained until acknowledged, and retried after connection returns. The app prioritizes the newest fix after an outage and shows connectivity changes sooner. Smarter location sampling: GPS capture adjusts around checkpoints and the finish, with different thresholds for running and cycling. Improved race-state handling: The app follows the server’s race status and shared start time, and fixes edge cases around finishing, stopping, and organizer resets. Clearer setup and troubleshooting: Setup gives guidance about background location and battery settings. Tracking diagnostics show location callback/fix times, last upload, and queued fixes. UI and localization updates: Runner setup and screens have been refined, with updates to English and Greek copy.
