What's New in Pro Compass

2.0.1

October 10, 2019

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!

User reviews

No data sharing with Watch App

Compass looks good and seems to function well as a compass. But I was expecting to be able to view and edit the waypoints I saved in the Watch App on my iPhone since both apps have the same name from the same developer. Was let down.

Accuracy

Every time I place it on the same fixed edge I get a different direction. Not accurate at all . Same problem I have with the one that was on my phone . Am I missing something?

Garbage

Wildly inaccurate. Use this app at your own risk but take a real compass with you. I want my money back

Won’t Display True North

The app won’t display true north. It just states NA (not available) in the true north slot. And it doesn’t show why it’s NA, or what to adjust to get it to show true north. Having true north is the only reason I downloaded this app.

Response from developer

This can happen for a couple reasons: 1) you have compass calibration turned off in iOS Settings (Privacy > Location Services > System Services) and/or 2) you denied permission for the app to use Location (also see iOS Settings > Privacy >Location Services). To display true bearing, the app needs both of these features to access magnetic declination.

Does not point to magnetic north

Shows pointing east not accurate at all. Waste of money
