I have, like many of you downloaded a bazillion compass apps over the years. I have the pleasure to introduce you to one I have downloaded, used a great deal on land and at sea and kept.
The Compass Eye
This is a compass that has some great features. It has the ability to use the camera on your phone. When the phone is held up as though taking a photo, you get a compass overlay on the view screen with the option to take a 3 point fix,
set clearing bearings or just a bearing to follow. When the phone is put back down to horizontal, you get a map view with the compass overlay.
Often at sea, your boat is not a very stable platform, the Compass Eye compass being fully gimballed does not change its reading at all. It is also possible to use the in app 8 x zoom facility which is great for identifying those difficult to see transits. It has the option of magnetic or true bearing display (set up in settings) and the red and green bearing lines once activated, are draggable which is great for clearing lines bearing set up. I don’t have a FLIR ONE but if I did, there is an Infra-red night vision facility (this I can see would be great for transiting in at night or in fog!). There is a GPS facility that will also give you speed and course over the ground. Naturally there is a screen capture facility that I used for the photos below. I have checked the accuracy against a compass I know is accurate and found no errors.
All in all a great app that I have no hesitation in recommending to you.
