I already tried iSailor or iRegatta. But these apps are for navigation. For navigation I already use (and pay for…) Navionics. Boatbeacon may work. Or not. But it costs me €14 only to try. So much for iOS support. Furthermore, the configuration software consists of .exe files. So much for Mac support.
In other words: it appears you ‘re confirming that the device is pretty much useless to iOS users and of limited use to Mac users. How come you advertise it as iOS and Mac compatible? Can I get my money back?
