As anybody who has followed my blogs would know- I swear by this app! I think its great to have goals and beat your personal bests, it gives you time/ distance and average calories burnt in a session. It was fantastic during my training for Run Melbourne and I use it to add up how many K's I have ran/ walked for the week! You can have playlists and voice updates on your progress as you go. Everybody who likes to run/walk for fitness should have this app!
