FitnessAI is a strength workout app for Android and iOS that builds sessions and adjusts them as users progress. Its AI-powered workouts specify sets, reps, and weights, drawing on real training sessions. Workouts can run 5–30 minutes and adapt to a user's schedule and available equipment; the app also changes weights and reps as strength improves. Guided videos and muscle visuals demonstrate exercise form. Strength tracking and a 3D BodyScan visualization help show progress. The maker says performance data can sync automatically with Apple Watch, and the iOS listing describes syncing workouts with Apple Health through HealthKit. The app is intended for people pursuing strength, muscle-building, toning, or weight-loss goals at home or in a gym. A free plan is listed alongside paid in-app memberships: 9.99 USD per month, 14.99 USD per month, 19.99 USD per month, 24.99 USD per year, 59.99 USD per year, and 89.99 USD per year. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the current period ends. The privacy policy says the company may collect usage data and use service providers for analytics, advertising, and payment processing.
