Your training, meals, and recovery in one place. Log it, see it, and watch your FitID level up with you.
FitID turns your fitness into a game. With your permission, it reads activity and recovery data from Apple Health—including steps, workouts, sleep, energy burned, resting heart rate, and more—to create personalized scores, skills, streaks, and insights.
CONNECT YOUR FITNESS
Bring activity, recovery, nutrition, and progress together in one place. Earn XP from healthy habits, develop fitness skills, maintain streaks, and watch your FitID evolve over time.
PERSONALIZED AI COACHING
Enable Live AI Coach to receive personalized check-ins based on your recent activity, recovery, nutrition, goals, and preferences. Chat with your coach about training, recovery, consistency, and nutrition, and receive practical next steps grounded in the data you choose to share.
AI-POWERED MEAL ESTIMATES
Take a meal photo or describe what you ate to receive estimated calories, protein, carbohydrates, and fat. You can also scan nutrition labels and packaged-food barcodes, review the results, and edit everything before saving.

PRIVATE COMPETITION WITH FRIENDS
Exchange a friend code with people you know and compete in friends-only FitID League rankings. There is no public or global leaderboard, and you control your visibility.
FREE TO START
Free members receive one AI meal estimate and three AI Coach chat messages each day. Optional rewarded videos can provide additional uses. Rewarded ads are never shown automatically.
FITID PRO
FitID Pro removes free-tier daily allowances and unlocks specialist AI coaches, premium avatar styles, automatic missed-day recovery, Health-history backfills, long-range analytics, and an ad-free experience.
PRIVACY AND CONTROL
Most health processing happens on your device. Live AI Coach is optional; when you enable it, selected health, profile, meal, photo, and chat information is sent securely through FitID’s relay to OpenAI for the requested AI feature. Health data is never provided to advertisers. Social data is stored through your iCloud account, and rewarded ads are optional and non-personalized.
FitID requires users to be at least 13 years old.
SUBSCRIPTION INFORMATION

The subscription renews automatically unless auto-renewal is turned off at least 24 hours before the end of the current subscription period.
