Compass Eye

Want to take compass bearings with your iPhone or Android device? Want a compass that doesn’t change its reading when the boat rocks? Compass Eye gives you this and more!

Compass Eye is designed to help navigate at sea and can be used much like a pair of Compass Binoculars.

Designed by a skipper for skippers, it can also be used on land as a bearing/marching compass and as it’s fully Gimballed; in the air too. Hold the iPhone vertically in landscape orientation to view where you are going and the bearings. You can also lay the iPhone flat to see the whole compass rose and heading on a live Google map.

Practical Boat Owner Magazine – “ impressively well, even on a moving boat..”

Shortly after its introduction, Compass Eye was chosen as Gizmodo’s App Of the Day
