Runtastic is a nice software that can be used for keeping track of your fitness activities directly on your Android tablet or smartphone. It has a really nice window layout where you can check how much distance you've covered, calories used, and even average pace. Moreover, you can use this application to establish yearly running goals and the software helps you achieve this limit.
If you're a competitive person, you can spice things up by completing challenges, and even check the Leaderboard to see which of your friends has run the farthest. Another cool thing about Runtastic is the ability to work with Android Wear 2.0, Google Fit, Runtastic Wearable Connect, Polar Flow, and Garmin Connect. Besides all the features provided with the free version, you can also pay for a premium membership to unlock additional functions.
For example, you can keep track of your personal records, get some extra motivation by listening to your favorite work-out song, start interval trainings, and more.
