Pro Compass replicates the look and feel of classic pocket compass hardware in use since the 1800s. The app uses advanced graphics technologies (normally reserved for games) to render 3D floating compass hardware for realistic operation.
Pro Compass offers true and magnetic compass modes using a damped rosette-style compass ring. Local sun and moon position are shown on the compass ring and continually updated. Pro Compass also displays location and altitude, with decimal and degree-minute-second position formats. The app contains a built-in two-axis inclinometer that drives two independent bubble levels and a bullseye level. In addition to settings for compass mode and position format, you can choose to display altitude in meters or feet, and select a dark or light interface style.
While Pro Compass was developed for watches with a built-in compass sensor (known as a magnetometer), it functions great on other watch models too, by using the device's gyro sensor to measure rotation. You can twist the watch's digital crown to adjust and calibrate the gyro to the sun position, moon position, or a known bearing. Using these references, the "gyro compass" is then able to give bearing. The calibration is easy, and can be repeated as often as desired to give accurate results.
Pro Compass reports accuracy from the magnetometer sensor in your watch. To improve results, operate Pro Compass away from magnets, electronics, or sources of electro-magnetic interference, including car dashboards, aircraft cockpits, metal structures, and other devices.
Like all our apps, we plan to continually improve and evolve Pro Compass for Watch. Please contact us with feature requests, suggestions, and general feedback. We'd love to hear what you're doing with the app! And if you don't already have Pro Compass for your iPhone, check it out!
