Prowess: Running Form
The gait lab for every runner
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
iPhone
Clip one small sensor to your laces and see how you actually move — impact, cadence, stride, symmetry — with one score that tracks your form run after run.
Your watch tells you how far and how fast. Prowess tells you how well you moved — and the one thing to work on next.
A small sensor clips to your shoelaces and measures every stride at the foot, where running actually happens: how hard you land, how quickly you load, where your foot comes down, and how your rhythm holds up as you tire. After your run, everything syncs to your phone over Bluetooth automatically.
YOUR PROWESS SCORE
Two numbers that capture the quality of your running: Economy (how efficiently you move) and Impact (how much force you take on, stride after stride). Watch them respond as your form changes — quality of movement, not just quantity of training.
STRIDE BY STRIDE, NOT AVERAGES
Scrub through any run step by step. See exactly when your cadence slipped, when impact crept up, and how the last mile compared to the first.
SEE WHICH PRO YOU MOVE LIKE
Compare the shape of your form against elite reference profiles — trail runners, road racers, triathletes — and see your closest movement match, plus the single gap that would move you closer.
TRAIN WITH A GOAL
Pick what matters and Prowess focuses on the metrics that move it:
- Return to Run — rebuild after a setback, carefully
- Optimize Stride — run more efficiently
- Increase Mileage — build volume without breaking down
- Safe Walking — movement insight at walking pace
- In-Depth Gait Report — the full picture
LIVE FEEDBACK
Start a guided session and get real-time cues on cadence and landing while you run — coach a change and watch it happen.
ONE SENSOR OR TWO
One pod gives you the core picture. Add a second for true left/right symmetry — one pod per foot, nothing inferred.
FITS WHAT YOU ALREADY USE
Send runs to Strava and Apple Health. Tag your shoes to see how your form changes as they wear.
HONEST BY DESIGN
Prowess is a training and measurement tool, not a medical device. It won't diagnose anything, and when a number is an estimate, the app says so. Your data belongs to you — never sold, never used for advertising, and you can delete your account (and everything with it) right from the app.
REQUIRES THE PROWESS SENSOR
Recording runs requires the Prowess clip-on sensor. Without it you can explore the app, but the numbers come from the hardware.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Reliability release — the boring kind that makes everything else better.
- Sensors connect faster and more consistently, especially the second pod
- Runs sync in the background the moment your sensor is in range
- Runs synced days later now keep their real date — and if the app has to estimate, it asks you to confirm the day instead of guessing
- Sensor firmware updates now install right from the app
- New Compare screen: see which elite movement profile you're closest to
