Prowess

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.

Verdict
The clearest difference is in-app purchases: Prowess at none against AvaSci's 2. AvaSci's advantage is update cadence (every 5 days vs every 2 months) and iOS requirement (13.0 vs 15.1). On price, ads and device support there is nothing between them.
