iOS Research Tool
Measure stability. Lower the number. Row better.
Wobble Rowing
Attach your iPhone to the craft, open Wobble, and start rowing. The app automatically orients itself to however the phone is mounted, then continuously calculates the Wobble Factor — a stability score your team can see in real time alongside stroke rate and speed.
Lower Wobble Factor = more stable craft. Watch all three metrics live and work together to improve.
