Obvisously they only looked at the US charting program. And the earlier version of iNavionics seemed to work ok but the charts were still off. It was when I updated that I began to have the issues! And they when they ask for feedback and problems and don't address them. Nope, not for me. I've learned my lesson there.

Can't speak how the iNavX works but I will say the developer at least will communicate with you via email. I asked him about charts and he indicated what we all know that you have to purchase them all over again (if you're outside the US) to use! Again another not for me. Maybe OpenCPN will come to the iPad. Not holding my breath there either.
