Onyx: Home Workout is a free fitness app for iPhone users developed by Onyx Inc. The app provides users with an AI personal trainer that counts reps, corrects form, and motivates users. With its interactive guided workouts, users can choose from Bodyweight, HIIT, Cardio, Strength Training, and more. The app is designed to provide everything you want in a trainer, at zero cost, and on your schedule.

The app uses advanced artificial intelligence and computer vision to give real-time tracking, feedback, and motivation. Onyx tells you to bend lower, straighten your back, and jump higher in real-time. The app is more motivating and life-like than any other fitness app available. Exercise tracking is only supported by TrueDepth devices, but users with older devices can still enjoy the catalog of workouts and videos. Your privacy is the top priority, and no video of you is ever sent to their servers. Try out Onyx: Home Workout and get fit at home with the world's smartest personal trainer.
