About Wobble Rowing
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.
