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?

Over the years, real theodolites have been used by famous scientists, engineers, and explorers. Lewis and Clark carried a theodolite on their expedition to explore the American west. George Washington, Thomas Jefferson, and Abraham Lincoln used theodolites for land surveying. You can see Jefferson's theodolite on display at Monticello.
In modern times, theodolites are valuable tools in science and engineering, and are used in the surveying and construction industries. The theodolite is a "go-to" instrument for all types of land, sea, air, and space measurements.
