Wobble Rowing vs Wobble Balance

Wobble Rowing measures the stability of your rowing shell during training and racing. In the spirit of "You can't improve what you don't measure", Wobble Rowing captures the motion of your shell and calculates the Wobble Factor which is a measure of how much your boat is rocking side to side. What Wobble Rowing measures: Wobble Factor — shell stability in real time Stroke Rate — strokes per minute Pace — minutes per 500 meters After each session: A per-minute summary shows your average pace, stroke rate, and wobble factor so you can track improvement over time. A CSV file is saved to your iPhone for detailed analysis. The CSV file captures data 10 times a second. Privacy: No personally identifiable data is collected. An anonymous ID is used to contribute data to a research database to help improve the model. GPS is used only to determine speed and location. Wobble Rowing is always free.

Wobble turns your phone into a personal balance meter. Stand for two minutes — Wobble measures exactly how steady you are, using the accelerometer and gyroscope already in your phone, and shows you the result on the spot. Wobble is a pure measuring instrument — think bathroom scale, but for your balance. You get precise, repeatable numbers; what you do with them is entirely up to you. WHAT WOBBLE DOES • Two-minute balance checks you can do anywhere — your phone is the only equipment you need (a foam pad or pillow helps for the harder phases). • Multi-condition assessment: different stances (wide, narrow, tandem, single-leg), different surfaces (firm floor or foam), eyes open or closed. Each condition stresses a different part of your balance system. • Trend chart that plots your stability across every recording day, so you can watch how the numbers move over weeks, months, and years. • Per-trial self-rating and per-session notes, so you can mark which days felt off and why. • Cohort comparison (optional): see how your readings compare to other Wobble users in your age group. • Coach-link mode (optional): a fitness coach, sports trainer, or movement professional can review your sessions and unlock advanced features for you. WHO IT'S FOR • People who want a clear, repeatable read on how steady they stand • Athletes monitoring balance across their season • Older adults watching how their balance evolves over months and years PRIVACY BY DEFAULT Recordings stay on your phone. Nothing leaves it unless you opt into cohort comparison or link a coach — and turning both off wipes your server-side profile. No ads, no tracking, no data sale. Full policy: wobble.flof.codes/privacy WHAT YOU NEED • A reasonably modern smartphone with motion sensors • Two minutes • Optionally, a foam pad or pillow for the harder phases • Optionally, a wall to lean against between trials Wobble is a measuring instrument, not a medical device — it gives you reliable numbers and leaves the decisions to you. It does not diagnose or treat. If you have concerns about your balance, please consult a healthcare professional.
