does it track for altitude too? i had one last time we went that only seemed to track forward motion. so it said i went 40 on a fairly flat area. then still said i was going 40 when i was bombing down a steeper hill.
It pretty much has everything and the speed check seems to be quite accurate. Check it out in the App Store, there's also a free version, though I prefer the full version which is about 79 cents.
