The iPhone GPS war up’d the anti with the 4.0 release of MotionX for the iPhone (above). They claim over 2 million users now and are the top ranked naviation app on the iTunes app store now. New in this version:
- All new user interface maintaining the same structure that you are used to
while improving all the graphics and sounds - MotionX Open Road Maps
- MotionX Open Terrain Maps
It seems to have caught up to GPS Kit 3.0 (below) for features and ease of use, though I still prefer GPS Kit’s interface which is a little more refined and iPhone-like and less like a computer arcade game (the developer specializes in those types of games).
Most notable in the GPS Kit 3.0 update is the huge battery saver features of turning off the screen but maintaining track recording while in the pocket just like the screen turns off when the phone is held to the ear during a phone call.
All the GPS apps need to get serious about cacheing maps BEFORE heading out to a trail. Cell phone service, let alone 3g, is spotty out in the mountains. Also allowing user specified tile source, not just Google or OpenMap. Maybe via the ability to setup “trips” (ala Tracks and Waypoints) based on the current visible map extent and then having the app pre-download map tiles down to the lowest zoom-level within a user configureable, say, 50 meg cache limit.
All apps are less than $10 from the iTunes store. MotionX is having a sale at $2.99 right now.
- If you want Google maps (including terrain) and care more about advanced features and a more sane interface, get GPS Kit.
- If you want Open Street Map base maps and pretty good advanced features but weird interface, get MotionX.
- If you are just a casual exerciser get an app like Trails (read New York Times review), RunKeeper, or rubiTrack that function mostly as a data capture and then interfaces with a desktop or web application to catalog your routes and graph progress.
