# Additions Training Insights: Calculate metrics including training load and readiness based on historical workouts from HealthKit, with filters for the most recent 7/30 days and local caching supported. Cold Start Guidance: Explain usage purposes first, then apply for health, location, notification and ATT permissions step by step to prevent system permission pop-ups right upon app launch. User Profile: Editable personal profile available in Settings; data is saved locally and synced via iCloud KVS. Energy Core Ring: Tech-style energy ring on the Today page and customized entrance animations for the home screen. # Optimizations Minimalist Premium UI: Adopt dark green accent color and section-based layout to replace stacked cards. Unify surface styles and micro-interactions across challenge, record and auxiliary pages. Align the layout of home screen share images with the structure of the Today page for a more consistent sharing experience. # Fixes Resolved cold start white screen and crashes caused by empty samples resulting from race conditions between splash ads and health permission requests. Fixed white screen appearing when sharing is triggered for the first time (the system share menu pops up only after share images are fully loaded). Addressed several known bugs.
