PainSled is a comprehensive fitness tracking app that connects your Concept2 indoor rower to various workout experiences and platforms like the Concept2 Logbook, Zwift, Strava, and more. It allows you to log rowing and heart rate data, export it in formats like TCX or CSV, and supports Bluetooth and USB data connections with Concept2 monitors.

With PainSled Premium features, you can sync workouts to multiple platforms, make your indoor rower act as a cycling power meter for online group workouts, and access additional visualization tools like the Stroke Scope for rowing stroke analysis and heart rate recovery tracking during idle periods.
