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.
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.

Ratings and Reviews
Professionally done but a minor gripe on optional "Datum Pack". If purchasing multiple apps from this programmer, be aware that the optional datum pack will only work within the app it was purchased in. Ie, the datum pack for pro compass won't work for pro camera without purchasing it a second time within pro camera.
Really well thought out and detailed application that is also extremely simple and easy to use. The interface is really smooth and the map feature is a huge plus when you need to flip over and see where you are on the map. It would be a huge value add if the topographic information could be an option as well. Great job guys!
I spent the majority of my military career as a Field Artilleryman. In the Field Artillery having an accurate compass is an absolute necessity! During my time I would have gladly used this application in lieu of anything readily available at the time.
Once you become accustomed to this application it is far more accurate and easier to use than the standard M2 used by the Army.
Having access to the datum packs further enhances this compasses use and accuracy.
I wholeheartedly recommend this application and the purchase of the datum pack to anyone who has a need for a compass in the field!
If there is a better compass app in the store I've yet to find it! Dr Hunter did an outstanding job.
