Some time ago I became interested in fartleks. When I went out to run in this way, I had to memorize the complete session and look continuously to my watch to see if I had to change the pace. So I decided to make an app to alert me when to change my pace and tell me the pace itself. Moreover it would allow me to stop worrying about having memorized the entire plan.
Deuteros designed the app that lies within the Sports category. The most recent update of the tool was released on Jan 9, 2015 and MyFartlek has been installed by over 5K users. The average score for this application is 3.2 on Google Play.
It's free of charge to get the installation package of MyFartlek, also, you can have a look at users' reviews on Droid Informer. The app works fine on Android 4.0 and higher. The download of the app is 100% secure.
