Just bought this App for my new Ipod Touch, Free or Pro upgrade only £3.99 its really good. Ran this morning in thick cloud cover, never lost the GPS signal once. Loads of info to be had, shows distance, time, split times, mapped my run and elevation etc. Still more options to work my way through. Its worth giving it a try only because it kept my GPS signal while Runkeeper kept losing it . Just thought I'd share this with you all. Happy running.
