Gamify
your gains.

Every honest rep is points on the board. Build a streak, climb the grid, and challenge friends head-to-head — all counted on-device by camera, so only the reps you actually finish ever count. The feed never leaves your phone.

PassFit workout summary showing 47 pushup reps counted on-device
Method

It knows a rep
from a twitch.

Thirty-three landmarks per frame, sixty frames a second, and a state machine that only counts a rep when the full cycle closes.

  1. 01

    Landmarks

    The camera traces 33 points on your body at 60 Hz with on-device pose estimation. Nothing leaves the phone.

  2. 02

    Signature

    Each exercise has a reference waveform. Your motion is matched against it in real time, frame by frame.

  3. 03

    State

    A four-state machine confirms the cycle — top, down, bottom, up. Half-reps die in the gate.

On-device

The camera feed never leaves the device.

Landmarks are extracted locally. Frames are processed in-flight and discarded. Your workout isn't training someone else's product — there's no wire between you and the inference.
