Having trouble with your WFTDA minimum skills laps, but not sure where you're speed is tailing off? This app can help you by tracking your times for each lap and comparing it to the required average to reach your target.

Although designed specifically for Roller Derby use, this timer can be used for any training which involves completing a certain number of laps or reps within a time period.

The setup screen allows you to adjust your target laps and timing, giving you an average lap/min and seconds/lap as you adjust your settings.

Once the timer is active, your progress is tracked each lap to tell you if you are over or under your target.

All results are recorded in a data table visible after timing is complete.
The results can then be saved to your SD card in a .csv format for reading in any spreadsheet software.
