First it didn’t but now it does.
The Digital Bearing Compass for some inexplicable reason didn’t work when I first installed it on my iPad Pro. It worked on my wife’s ipad but even with Thomas’s help, I couldn’t get it to work on mine. Today, whilst cleaning out unused apps, I fired it up just to be sure before deleting it and lo and behold, it works perfectly. Must have had some updates. As far as the app goes, it’s brilliant, I love it!
