Bar speed, measured from your phone

Velocity-based training without a sensor, a tether or anything attached to the bar. Film a set the way you already film one, and get per-rep speed, range of motion and an estimated 1RM back.

Works on videos you already have

Old clips count. Set the recording date to when you filmed and your trends build from training you have already done.

Every rep, not just the set

Per-rep speed and range of motion, so the fatigue across a set is something you measure rather than guess at.

Built for coaches too

Athletes film their own sets. You get their numbers, their trends and a place to respond.

How it works
1. Record

Any phone, filmed from the side.

2. Upload

Add weight, reps and how hard it felt.

3. Analysis

The plate is tracked frame by frame.

4. Insights

Per-rep speed, ROM and long-term trends.

Built on a Master's thesis validating camera-based velocity against a tethered linear position transducer. The research behind it.
