Theodolite for Apple Watch Now Available from Hunter Research and Technology

Hunter Research and Technology has released Theodolite for iOS devices, their Augmented Reality app is now optimized for Apple Watch. Theodolite for Watch combines a compass, inclinometer, and GPS into one app.



The app combines data from the device sensors into an Attitude and Heading Reference System (AHRS) layout that resembles the glass cockpit of a modern aircraft. It displays compass bearing (yaw angle), pitch angle, and roll angle in a compact format.


The app is compatible with Apple Watch Series 1 through Series 5, running watch)S 6 or later. On Watch models without a built-in compass sensor, the app uses the device’s gyro sensor to measure compass angle. Twisting the the Watch’s digital crown can be used to adjust and calibrates the gyro to the sun position, moon position, or a known bearing.


Theodolite for Watch is available through the iOS App Store on an iPhone/iPad. To find the app in the Apple Watch App Store, search for “Theodolite for Watch.” The price of the app is $1.99 USD.
