Peak AI (iOS app)

Peak AI is an iPhone and iPad workout app for strength training and bodybuilding that combines workout tracking with AI coaching. It logs sets, reps and weights, detects personal records, and uses ChatGPT within the app to create workouts and give coaching. Peak AI is built by lifters for lifters and aims at people of any fitness level who want to build strength, gain muscle, lose weight or improve form.

The user logs each set, rep and weight against an exercise library, builds custom workout templates and switches between kilograms and pounds. Peak AI's coach adds a body scan, personalized workout recommendations, real-time progress analysis and custom program creation, along with form guidance and training adjustments. A workout history keeps past sessions so progress can be reviewed over time.

Progress tracking in Peak AI covers several kinds of personal record, including weight, reps and volume, along with PR streaks and achievement celebrations when a new record is set. Progress is shown visually, and the detailed workout history supports goals such as building strength, gaining muscle, losing weight, improving form or simply tracking progress across training sessions.

Peak AI is free to download. Premium adds unlimited AI workout creation, body scan analysis, personalized coaching and custom training programs, with a 7-day free trial followed by $9.99 a month; a $59.99 Pro Access purchase is also listed. The app requires iOS 17.0 or later, also runs on Macs with Apple M1 or later and on Apple Vision, and is in English. Peak AI's developer states that no data is collected.
