Run 10-20-30

Run-10-20-30 is an App. their functions as a stopwatch for the 10-20-30 running concept, but not only, it also allows you to track your speed via GPS, and you will have a history of your last performances.

10-20-30 is an interval training concept for runners, there was invented by Jens Bangsbo from Department of Exercise and Sport Sciences at University of Copenhagen.
The concept has proven to be both entertaining and more stimulating than regular running and runners achieve significant performance improvement and improved health.

The concept is performed the following way:
- 30 seconds of slow running (jogging),
- 20 seconds with moderate speed (running), and
- 10 seconds sprint.
- Repeat 3-4-5 times followed by a 2 minutes pause, then start again.

Run 10-20-30 allow you to customize your intervals length, so you can have intervals length different from the standard 10-20-30 seconds intervals.
From version 2.0, you can also activate GPS for speed measurement, and study your performances afterwards in the statistics (this feature has to be activated via the the setup).
If you have an external storage (it might been emulated), you can find the statistics in the Run-10-20-30 directory in comma separated value (csv) formatted files. You can use these files in a spreadsheet or where you else think it would be interesting (this feature has to be activated via the the setup).

This application will, different from other 10-20-30 applications, continue to works, also when the device (phone) go in power save mode, equal: the screen is black.

NOTE:
I know the user interface is a bit simple (not flashy), but I try to support as many devices as possibly, even devices with very old version of Android, the positive side of this is it keep the app small and tidy.

The app will try to upload the set-up to my server, so I can analyze how it is used, this is done so I better can decided what to do next. The upload can be turned off by un-check the "Help the architect" in set-up.
