Rowly - Rowing Performance

Rowly is a rowing performance tracking app designed for on-water training and post-session analysis. It uses your phone’s GPS and motion sensors to record key rowing metrics in real time and presents them in a clear, practical way for review after each session.

Rowly is free to use for real-time tracking during your sessions. See your pace, stroke rate, distance, and more as you row. More extensive analytics, integration with heart-rate sensor, and uploads to Strava are available in the Premium plan - with which you help me cover the cost of development.

Rowly is suitable for both individual rowers and coxswains who want better insight into pace, rhythm, efficiency, and consistency during and after training.

Uses advanced sensor fusion combining GPS, accelerometer, and gyroscope with Kalman filtering and zero-crossing stroke detection for accurate speed, stroke rate, and boat stability tracking — no external hardware needed.
