The first version of run302010 Pebble application. Runners greatly benefit from a controlled fartlek workout referred as 30-20-10. run302010 is an excellent tool for the 30-20-10 workout and a great companion for any run tracking application used on a smartphone. Start run302010 on Pebble during your run. It counts the seconds for you, signals end of each interval by a short vibration, and displays actual time, so Pebble still serves as a watch. The application is extremely easy to use. Select button starts and pauses the workout. Double-click on select button resets the workout. End of each interval is signaled by a short vibration. This can be combined by a short visual check in order to remember what interval is in progress. Up (+) and down (-) buttons are used to set number of laps - how many times the 30-20-10 workout should be repeated.
