Useful for outdoor types, Spyglass acts as an augmented reality compass. The app features tactical GPS, which lets you find and track your location with coordinates in both Geo and Military formats. The app also allows you to store locations you'll need later on (such as where you parked your car), and it has advanced features such as star tracking, an optical rangefinder that measures the distance to objects, and a MIL-SPEC compass that updates in real time based on the azimuth circle.
