I quit using it

It seems to be an OK sailing app. but I couldn’t get past the way it stitched the “paper" charts together (there seemed to be trouble at the seams, and loading the charts when I needed them, etc). I have SEAiq on also and ended up always using that instead. It’s $10 so also a good value. I wish I hadn’t have spent the money on iSail because I never use it now.
