Fit2AI helps athletes review workouts with structured data and practical AI analysis. Connect your COROS account, import recent Apple Health workouts, sync workouts, parse FIT details, review personal-record candidates, inspect route maps where GPS data is available, and ask follow-up questions about a single workout. When the same workout is available from both COROS and Apple Health, Fit2AI shows the COROS copy and hides the duplicate Apple Health copy so summaries and insights do not double count it. The app focuses on the workout you choose, including distance, time, heart rate, power, cadence, laps, route summaries, and available FIT samples. Free users can try AI features with 5 total interactions. Fit2AI Pro unlocks up to 50 AI interactions per UTC day through an auto-renewable monthly subscription. Fit2AI is not a medical service. AI responses are informational and should not replace medical, health, or professional coaching advice. Fit2AI is an independent app and is not affiliated with, endorsed by, or sponsored by COROS.
