Theodolite is a multi-function augmented reality app that combines a compass, GPS, map, photo/movie camera, rangefinder, and two-axis inclinometer. Theodolite overlays real time information about position, altitude, bearing, range, and inclination on the iPhone’s live camera image, like an electronic viewfinder.

Uses are endless, and Theodolite is great for outdoor sports, hiking, boating, hunting, golf, sightseeing, photography, and navigation. The app is used in the field every day by surveyors, geologists, architects, engineers, military personnel, competitive sportsmen, and search and rescue workers.

Theodolite set a new standard for augmented reality navigation apps when it debuted in 2009. It has been featured numerous times in iTunes (including honors as a “Rewind 2010” app), and has been the #1 selling Navigation app in iTunes stores around the world.
