FAQ

Frequently asked questions

Do I need a watch or a treadmill?

No. Prowess is one lace-clip sensor — the Prowess Pod. Clip it to your shoe, run wherever you already run, and it measures how your body actually hits the ground. No watch, no lab, no camera array.

Can one sensor track both legs?

One Prowess Pod mounts on one shoe and measures that foot's strikes directly — impact, cadence, ground contact, and symmetry — then models your whole-run picture from them. It can't see the difference between your feet; for true left/right comparison on every step, the Prowess Pod Pair puts a sensor on each shoe.

How accurate is it?

The Prowess Pod measures at the foot with a high-precision inertial sensor (accelerometer + gyroscope), sampling every foot strike — not a wrist estimate averaged over a mile. In our testing against GPS and treadmill, distance lands within roughly 2–3% and cadence within about a step per minute. It's built on patented core tech (US 10,820,836) and patent-pending load modeling.

What is the Prowess Score?

One number, measured at the foot. It rolls impact, symmetry, cadence, and ground contact into a single read on how today's run loaded your body — so you know what to work on and when to back off. Details on How it works and The science.

Do I need a subscription?

No. The Prowess athlete app is free. The optional Coach and Clinic dashboards ($99/mo) are for teams and PTs managing multiple athletes.

Which phones does it work with?

The app runs on current iOS and Android devices and connects to the Prowess Pod over Bluetooth. Setup takes a couple of minutes — see Support.
