How does the camera count my reps: motion-verified counting in Quick Burn
In Quick Burn, your camera counts your reps, and it does so by verifying the motion. A rep only counts when your limb genuinely travels all the way to the target; small wobbles and jitter never count. The footage never leaves your phone — what gets analysed on the device is the geometry of your skeleton, not the image.
To understand how, start with what the camera sees. As the app watches, it tracks 26 body joints live — shoulders, hips, knees, wrists, ankles and feet. What is recorded is not a video but the position of those points relative to one another; in a crunch, squat or bicycle, the path your limb travels is read from that geometry.
Several gates decide together whether a rep counts. The distance your limb covers is normalized to the scale of your body and has to clear a minimum-travel threshold. In other words, the movement must actually be completed — the limb has to reach the target. A small shudder in place, sensor noise or a half-finished move cannot clear that threshold, so it physically cannot be counted.
Tempo is one of those gates too. It is not only how far you move but how long the movement takes that is taken into account. That makes it impossible to fool the counter by twitching quickly at one point; the count is looking for a controlled, complete rep, not a careless shake.
If you do not know the movement at all, that is fine. The moment you get into position, the app explains how to do it, so you learn the correct form from the start. Fair counting begins with the movement being shown correctly first.
The numbers are yours. During a session you can nudge the rep count or duration up or down for each exercise, tuning it to how you feel that day. The system does not force you into a mold — it verifies the target you set.
All of this counting happens on your device. The camera image never leaves your phone and is never uploaded to a server; what is analysed is the geometry of the skeleton points, not the image. Privacy here is not a setting — it is the architecture. Yogin’s platform clients are being rolled out gradually. The homepage links to a live store listing when one is configured; otherwise, it offers platform-specific early access. See our FAQ for more questions.
