About
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. 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. Uses are endless, from basic land surveying to navigation, and the app is great for hiking, boating, hunting, sightseeing, sports, and finding your way around.
