Use Chrome on your phone or laptop. Allow the mic for voice commands, and the camera if you'd like the form check.

Meet your future self

A few questions so your coach can build a workout that fits you.

Your level & body

Your coach adapts the exercises and timing to this.

Add your photo

Your coach takes on your face as your "future self". The photo is resized and kept on this device only.

JPG/PNG/HEIC, any size. It's compressed to 512px before saving.

Phase 2: this photo would drive an AI-generated 3D "future self" avatar with your face and voice.

      What's inside

      Built for the problems in your brief

      🎙️ Two-way voice

      The coach talks, and you can interrupt at any time ("pause", "skip", "too hard", "how long left?"). Barge-in stops the coach mid-sentence.

      ⏱️ Drift-free timers

      Timers are clock-based, so they stay accurate if the tab freezes or the phone sleeps. Includes 3-2-1 beeps, a halfway cue and spoken rest countdowns.

      📐 On-device form check

      Our production pose engine on MediaPipe: squat depth, back angle, knee alignment and tempo, a form score, and calm, debounced coaching cues. Camera use is opt-in and stays private.

      Already in production code

      The form check runs on PhysioTrack, our camera-based exercise coach

      This prototype doesn't use a throwaway script. It runs the same pose engine we built for PhysioTrack, a TheGradleW app where physiotherapists prescribe home exercises and patients are coached through their phone camera.
