A Rowing Research Tool for iOS
You can't improve what you don't measure. Wobble gives rowing teams a real-time stability score — so you have something concrete to work toward.
How It Works
Attach your iPhone to the craft in any orientation — Wobble automatically detects how it's mounted and orients itself accordingly. From there, it continuously computes the Wobble Factor: a single stability score derived from the phone's motion sensors. Lower is more stable. Stroke rate and speed are displayed alongside it, giving the team the full picture in real time.
A single derived stability score. Lower means the craft is more stable. Watch it in real time as the team adjusts.
Attach the phone however is convenient. Wobble auto-detects orientation and compensates — no manual calibration needed.
Wobble Factor, stroke rate, and speed — all on screen in real time as the team rows.
Just an iPhone attached to the craft. No sensors to buy, no devices to pair, no subscriptions.
Available on iOS
Wobble doesn't tell you what to do. It gives you a number, and lets your team figure out how to improve it. That's the point.
