 Hunter Research and Technology today is pleased to announce the release of Theodolite 2.3 on the iTunes App Store. This novel multi-function augmented reality viewfinder app serves as a compass, GPS, map, zoom camera, rangefinder, and two-axis inclinometer. Theodolite has been featured numerous times in iTunes, including “Rewind 2010: Hot Trends in Apps” and “Augmented Reality: The World Around You”. It was the #1 selling US Navigation app in December 2009 and September 2010.

Based on the concept of a centuries-old astronomical instrument, Theodolite overlays real-time information about position, altitude, bearing, range, and horizontal/vertical inclination on the iPhone’s live camera image, turning the iPhone into a sophisticated electronic viewfinder. Theodolite lets users take geo-stamped and geo-tagged camera images directly from the app, with 2X and 4X digital zoom options, and contains a built-in map with standard, satellite, and hybrid views. Uses are endless, and the app is great for navigation, outdoor sports, home projects, and photography. Theodolite is used in the field by surveyors, geologists, avalanche researchers, military personnel, and search and rescue workers around the world.

Theodolite comes in three versions – Free, Basic, and Pro – to cover a range of customer needs. The flagship Theodolite Pro includes features for serious users, such as a zero reference angle mode, an A-B calculator for height, distance, heading, position, triangulation, and relative angles, e-mail export with KML data, system-wide clipboard integration, percent grade display, optical rangefinders, military grid reference system (MGRS) coordinates, universal transverse Mercator (UTM) coordinates, and four latitude/longitude formats.

Version 2.3 of Theodolite implements performance improvements for smoother rendering, lower CPU usage, and a reduction in overall memory usage. The app also sports a refined UI look and feel. Basic and Pro versions of the app now take high res 960×640 screenshots on devices with a Retina display and include a faster photography engine with buffered image saves. Theodolite Pro adds colored lens filters to improve use in dark conditions and preserve night vision, a recalibration of optical rangefinders with proper lens specs on all devices, and an additional mil-based rangefinder. With these new capabilities, Theodolite continues its role as a technology demonstrator app, showcasing the latest and greatest in iOS hardware and software capabilities.

As the name suggests, the demo version “Theodolite Free” is available for free on the iTunes App Store. The mid level “Theodolite Basic” costs $1.99 (USD), and the full-featured “Theodolite Pro” is $3.99.
