Great! Best free app – Runtastic Road Bike GPS Review

Someone said eats the battery, then turn it on battery saving and turn the screen off. Just went on a 20 mi 1.5hr and it used less than 15% of my battery on my one and half year old phone! Anytime you use GPS the battery is going to be used some. But the killer is leaving the screen on. Also love the different metrics the app has.
