A workout partner that actually watches your form.
AxionFit turns your iPhone camera into a form coach. Using Apple's Vision framework, it maps your body in real time as you move, so it can count reps, flag technique mistakes, and talk you through corrections — all without sending a single frame off your device.
Pose detection
Apple's Vision framework tracks your joints frame by frame while you train.
Technique feedback
Your movement is compared against clean form for each exercise, rep by rep.
Voice coaching
Spoken cues keep you correcting form mid-set, no glancing at the screen required.
Camera in, coaching out.
Open AxionFit, pick an exercise from the library, and prop your phone up so your full body is in frame. From there, everything runs locally: pose tracking, rep counting, scoring, and the voice cues that follow. Your workout history, streaks, and achievements are saved to your device and can optionally sync to Apple Health and iCloud.
Built by one person.
Vaibhav Gupta
An iOS developer who built AxionFit to solve his own problem: training alone, with no one around to check his squat depth or lockout form. AxionFit is built natively with SwiftUI and Apple's Vision framework, keeping every part of the workout — camera, tracking, and coaching — on the phone itself.
