The legendary iOS compass app is now available for Apple Watch! 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, and contains a built-in two-axis inclinometer that drives two independent bubble levels and a bullseye level. 
New in Pro Compass for Watch version 2 is a map screen and waypoint manager. You can add waypoints on the map or at your current location, and view waypoints on the compass ring to visualize their bearing from your current location.
Pro Compass has settings for compass mode (true or magnetic, degrees or mils), distance/altitude units (feet or meters), and position format (decimal degrees, degrees-minutes-seconds, MGRS, USNG, UTM, UTM-B, and Maidenhead Locator System). The app has six color schemes, including two night vision modes - midnight red and luminescent green.
Pro Compass for Watch is recommended for Apple Watch Series 5 and later (including Ultra). Apple Watch Series 4 and older do not have a compass sensor and will not show compass data. On older devices, the app uses 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 able to give bearing. The calibration can be repeated as often as desired to give accurate results.
Accuracy note: 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.
Developer note: 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!
