This app encourages users to utilize their interval training feature. This feature is easy to use because it is integrated with their voice coach who well notify the runner when the next interval is arriving.
The audio coach provides updates at each checkpoint. The trainer is capable of telling the user total duration, pace, speed, calories burned, calories burned, and heart rate (if wearing a monitor).
The completed workout's map is saved along with all of the data collected about the workout. Because of this feature, users can easily track their improvement and accurately set goals.
Runtastic is capable of informing users of their pace, distance traveled, heart rate, and altitude, along with a detailed map that is saved into "history".
Stats such as top speed, speed of each interval, fastest/slowest parts of a course, etc. Where applicable, graphs and maps routes will be display for a visual representation.
RunKeeper displays your route using Google Maps and tracks distance, duration, speed, pace and calories burned. You can also input your runs manually (useful when running on treadmills) to add them to your "workout logs".
