your gains.
Working out alone shouldn't mean nobody's counting. PassFit turns every rep into a streak worth defending and lets friends push you on — no coach, no gym, and not a single camera frame ever leaving your phone.
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.
Counts [accuracy %] of reps correctly across lighting, angles, and floor exercises.
-
01
Landmarks
The camera traces 33 points on your body at 60 Hz with on-device pose estimation. Nothing leaves the phone.
-
02
Signature
Each exercise has a reference waveform. Your motion is matched against it in real time, frame by frame.
-
03
State
A four-state machine confirms the cycle — top, down, bottom, up. Half-reps die in the gate.
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.
- Latency
- 60 fps, zero round trips
- Storage
- Workouts persist on your phone
- Social
- CloudKit-scoped to your account

Train alone.
Win together.
Add friends by @username, send rep gifts, and push each other through 24-hour challenges. Every rep is counted on-device, so the leaderboard reflects work that actually happened.
@username friendships
Every account gets a unique handle. Search the exact one, send the request, done. No contacts upload, no follow-graph harvested.
Send a rep gift
Drop a friend a clean set of reps with a note. They get a push, you get a witness — the smallest unit of "I see you working."
24-hour challenges
Pick a target and a friend. Whoever logs more verified reps takes the round. Quit early and it doesn't count for either side.
