FitnessAI vs Miles

FitnessAI is an Android and iOS workout app that builds strength sessions and changes them as users progress. Its AI-powered plans draw on real training sessions and specify sets, reps, and weights. Workouts can run from 5 to 30 minutes and adapt to a user’s schedule and available equipment; weights and reps also adjust as strength improves. Guided videos and muscle visuals demonstrate exercise form, while strength tracking and a 3D BodyScan visualization show progress. The maker says performance data can sync automatically with Apple Watch, and the iOS listing describes workout syncing with Apple Health through HealthKit. The app is aimed at people pursuing strength, muscle-building, toning, or weight-loss goals at home or in a gym. A free plan is listed. Paid in-app memberships range from $9.99 a month to $89.99 a year, with additional listed options at 14.99 USD and $19.99 a month, and 24.99 USD and $59.99 a year. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the current period ends.

Miles is an iOS running coach for goals ranging from a first 5K to a marathon. Miles Pro builds a week-by-week plan around current fitness and adjusts it when runs are missed. During runs, it tracks GPS pace and gives audio cues when pace moves off target, alongside structured intervals, tempo runs, and long runs. After each run, it provides coaching analysis of what worked and what to change. Plans cover 5K, 10K, half-marathon, and marathon goals; treadmill runs also receive structured workouts and post-run analysis. Miles Pro supports Apple Health and Bluetooth heart-rate monitors. The free plan includes iPhone run tracking, goal setting, and a plan preview. Miles Pro Monthly costs $14.99 a month; Miles Pro Annual costs $99.99 a year and starts with a 7-day free trial. The App Store lists compatibility with iPhone running iOS 18.5 or later and Apple Watch running watchOS 11 or later. Miles collects location and fitness data including GPS, pace, cadence, heart rate, and workout time. With consent, anonymised pace and distance data may be shared with an AI partner.
