If you’ve used any of the free tracking apps — like Google’s My Tracks, which records your path, speed, distance and elevation change while you exercise and then maps the route, charts elevation and speed, and tots it all up in a set of statistics — you’ll understand the concept behind Runtastic Pro. Runtastic Pro additionally promises to help you reach goals and track health improvements. It uses the same raw data as GPS tracker apps — distances and so on supplied by the smartphone’s GPS receiver — but it’s jazzed up with a lot of extras.
