Read full descriptionHide full description
The Active Tools DataFlow app allows easy data transfer to Rowsandall, Strava, Dropbox, etc. This includes both performance data and the tracks of the courses you steered. You can then review and analyse both these on-water workouts and any land-based ones you have transferred to those sites. The app also lets you update the firmware on your ActiveSpeed and in the future it will let you see, and analyse, data and force curves from our RapidFit Coaching and Data oarlocks.
