miBearings app for iPhone and iPad

miBearings lets navigators quickly and confidently convert between true and magnetic bearings.

Given a magnetic bearing, calculating your true bearing should be plain sailing - you just add the magnetic variation right? Or was it subtract? Now do you add or subtract a westerly deviation? Does this sound familiar?

With miBearings in your pocket you will never have this problem again! The clear and simple interface provides instant visual feedback on the relationship between your magnetic and true bearings.

Navigation has never been so straightforward.
