Theodolite is a multi-function augmented reality app that combines a compass, GPS, map, photo/movie camera, rangefinder, and two-axis inclinometer into one indispensable app. 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 around the world.

Theodolite set a new standard when it debuted in 2009, and has been a #1 selling navigation app worldwide. It has been featured in iTunes, included in Apple special event keynotes, and even filmed by Apple at the Great Wall of China! Where will you take Theodolite on your next adventure?

Theodolite works on any iPhone or camera-equipped iPod Touch.
