About Pro Compass

Pro Compass replicates the look and feel of classic pocket compass hardware in use since the 1800s, adding modern features and technologies. The app uses advanced OpenGL graphics (normally reserved for games) to render 3D floating compass hardware for realistic operation.

Pro Compass offers nine different compass modes with direct read, traditional, and rosette styles capable of displaying degrees, quads, or mils (the direct read mode shows a North-South needle and reversed East-West convention). In all display modes, Pro Compass shows both magnetic and true direction simultaneously, with a rotating outer true ring that is automatically adjusted for local magnetic declination. Sun and Moon position are marked on the compass rings and continually updated.

Pro Compass displays location and altitude, with decimal, degree-minute-second, UTM, and MGRS position formats. An optional "Datum Pack" adds over 230 geodetic datums covering regions and countries on all continents around the world. The app also contains a built in two-axis inclinometer that drives two independent bubble levels and a bullseye level. The inclinometer has angle readout dials for each axis, making it useful for many different types of measurements including slopes, pitches, sight lines, and geological angles like dip and strike.

After using Pro Compass, you'll see why it's the best and most realistic compass available on the App Store! Also be sure to check out the new Pro Compass for Watch, available for all Apple Watch models running watchOS 6 or later.

***** IMPORTANT ACCURACY NOTE *****

Pro Compass reports accuracy directly from the magnetometer sensor in your device. This accuracy is determined by the hardware, not the application itself.

To improve results, operate Pro Compass away from any electronics or other sources of electro-magnetic interference, including car dashboards, aircraft cockpits, metal structures, and other devices.

Please contact the developer via the support link if you need additional information about accuracy or operation of Pro Compass.

最新版本2.0.1更新日誌

Last updated on 2019年10月10日

歷史版本

2.0.1 is a quick bug fix update to correct a graphics bug that caused a stray compass needle to be drawn on the ring instead of a full moon (Halloween werewolf bug?). In version 2.0, graphics have been touched up and modernized without changing the app's classic look and feel. New icon. Interface updates for iOS 13 and new devices. Sun and moon indicators added to the compass ring to match features in the new Pro Compass for Watch app. Seven new datums added to the datum pack. Please help support quality app development by leaving a rating/review for Pro Compass on the App Store, and check out our other products and extras. Thanks!

1.2.1

2015年03月13日

This is a quick update to fix a graphics freezing problem caused by iOS 8.2.

1.2

2014年10月21日

Minor interface tweaks for iOS 7, iOS 8, and new devices. Change in UTM and MGRS coding to correct position calculations when using legacy datums (such as NAD-27) and ellipsoids (such as Clark 1866). Note that this enforces a ten-letter shift in the northing of new vs/ old MGRS 100,000 meter square IDs.
