Screen has to be on??? – Run Tracker: Best GPS Runner to Track Running Walk Review

Doesn't work when u turn the screen off! So u start the tracking, then turn the screen off, and when u turn the screen back on several miles later u realize it hasn't been going the whole time! Not to worry though, it resumes once u wake the phone...so u successfully track exactly 10 seconds of your run. Useless.
