Rowing SPM is a free rowing strokes per minute (SPM) counter.
Now Supports Apple Watch
Simply tap the 'Stroke' button and the app will calculate the current stroke rate and also the average stroke rate for the last 5 and 10 strokes.
The average stroke rate for the whole piece is also shown along with the total strokes taken.
Perfect for use by a coach or cox during a rowing outing or for calculating the stroke rates of boats from the side of the river/lake.

Warning: If you use this app whilst in a boat on the water and your device gets wet, it will probably break it so the exercise of caution is strongly advised.
Waterproof cases are available.
