3D Sailing Compass

Still works on ios11 works great a keeper get this app

At first I was a little skeptical because the new iphone 3GS already has a compass app. However, I sail a lot and have always thought it would be awesome if I had a 3D Compass on my iphone while sailing. Well, now it's possible, and it actually does a pretty good job. If you area sailer, I highly recommend this app. 5 Thumbs up.

As a sailor, I appreciate the appearance of this compass interface -- graphically, it's well-executed, and it has a more intuitive look when you're holding the iPhone vertically. But bear in mind that all you get with this app is a different look. Horizontal or vertical, it gives you exactly the same the compass reading you'll get the from the compass app that was included with the iPhone -- and the stock compass also gives you handy digital bearing readout (which this one doesn't).

Ignore my previous review, this app does work, you just have to let it use your current location.

This app shares the same tragic flaw as the Apple compass: There is no visual indication as to whether the thing is pointing to true north or magnetic north. Either Apple or these guys are going to get someone killed. This app goes Apple one step worse: It demands to use your GPS coordinates even when you are using magnetic north, thereby seemingly indicating you are, in fact, using true north when you're not. Cute but deadly.
