Based on a centuries-old astronomical instrument, Theodolite is a cool new multi-function augmented reality app for the iPhone that serves as a compass, GPS, map, zoom camera, rangefinder, and two-axis inclinometer. Theodolite overlays real time information about position, altitude, bearing, and horizontal/vertical inclination on the iPhone’s live camera image, like an electronic viewfinder. Uses are endless, from land surveying to navigation, and the app is great for hiking, boating, hunting, golf, sports, sightseeing, and finding your way around.
Theodolite lets you take camera images and screenshots directly from the app, with 2X and 4X digital zoom options. You can choose to stamp geographical data and custom notes directly on the saved image for later reference. View your current position on the built in map view, with standard, satellite, and hybrid modes. On an iPhone 3GS, bearing is updated live on the map with both fixed view and world rotation. The app even includes a handy "A-B" calculator to compute height of landmarks, distance to landmarks, triangulate position, compute distance/heading between points, show relative angles between observations, and show two points on the map. The calculator includes an option to copy results to the system-wide clipboard.
Theodolite works on any iPhone. GPS functionality requires an iPhone 3G, 3GS, or 4. Compass functionality requires an iPhone 3GS or 4.
