Dont buy - fatal flaw!
As many others, I have purchased / tried several navigation programs. As a owner of almost a dozen garmin devices i am hooked on their ecosystem and they make great devices; unfortunately bluechart mobile is not one of them.
Only after two years of tedious use on my ipad, did i find this flaw. I purchased a new ipad and learned that Garmin has strategically omitted the ability to export waypoints, routes, tracks etc. to a new device.
A great product as a plain map, but if you record any data, dont plan on upgrading and pray your device never breaks. Most other software allows you to export, so there are many other great options out there.
