The SmartRow App (together with the SmartRow-conversion) will turn your WaterRower into a lab grade ergometer. It will not only show you power distance work-per-stroke calories etc. it will show you each force-curve heart rate graph and much much more! It keeps track of your workouts and even shows you well-known fitness metrics like 'Watts-per-Beat' and 'Watts-per-Kilogram'.

This is the best training tool you can invest in—after hiring a coach of course!
