Sure, you can use the regular maps available for iOS to get around, but those who trek around the wilderness need a bit more muscle. Well, Spyglass offers just that, employing all of the sensors Apple's devices house and tossing in a bit of augmented reality for good measure. The app overlays compass, GPS and location info on top of visuals captured by an iPhone camera or the map itself. There's also a load of more advanced navigation tools for in-depth tracking -- options that include a high-tech viewfinder (HUD), MIL-SPEC compass, gyrocompass, tactical GPS, speedometer, altimeter, rangefinder, sextant and more. Real-time tracking based on the location of stars, the sun and the moon is possible too, as is the ability to save waypoints for the return trip. You can also save specific spots for later, snap pictures with the data overlaid and employ one of a dozen different coordinate systems ranging from civilian to military. Sound too good to pass up for that next mountain excursion? Spyglass is available now via the iTunes App Store for $3.99.
