Use your iPhone/iPad/Watch as a marine instrument display (MID) and navigation aid instead of buying an expensive mast or a repeater display. Mount your iPhone/iPad to the mast or the cockpit and use it just as a traditional device. You can even attach the iPhone to your wrist using a waterproof armband or wear Apple Watch. MID allows you to create and follow routes and track your path. It also calculates the angle of heel. Send/receive data through iCloud (e.g. remote anchor alarm).

Good, but..

The app works great while sailing, but it won't save my tracks. I've tried several times to save them and the app crashes every time. They also seemed to have changed the font and it looks worse.

For Sail ,


I like the app, I think it has many nice features however it crashes every time I swipe to the map page. I have two identical first generation iPads with this app installed and nothing else. Both iPads are running the latest IOS (V5.1.1) and both devices crash the same. I've e-mailed the developer twice and still have not received a response.
