The places and roads I prefer to ride, phone gps' and signals get lost. A satellite based gps works much better than a phone gps, imo. I would think the app needs your gps on, I just wonder how well that would work on remote rides?
Phone based GPS uses the same signal as a stand-alone GPS unit. I know I am able to use GPS-based only apps on my iPhone when no data or voice signal is available.
This app claims to not need a data signal, only GPS.
