Crumphead is wrong

Crumphead you absolutely can but charts for Australia. For a fraction of the cost of paper charts. I use this App as a back up to our Navigation system, regularly. They have fixed the WP problems, hurray! I love the route system and the detail on the charts are fantastic. I import GRIB files with the greatest of ease. Sure, as we're in Australia we need to buy charts but i think thats a very reasonable request. I also have other Nav products but iNavx wins hands down. Well done, love it.

Most of the features and usability is great but it’s let down by dateline issues. I’ve been told by iNavX that this was going to be fixed for 4 years now and still nothing. I can only assume they are paying lip service to shut me up whilst having no intention of fixing the issue. Disappointing at best.

Not fit for purpose

Do not buy this app. It is not fit for purpose. The app costs a small amount then to use it you buy access to the global chart dataset. You download areas of the world in which you are interested.

The underlying chart data has no information at all about the light characteristics of lighthouses. None. This renders the app almost useless and potentially dangerous. Lighthouse characteristics are an essential component of a chart. To sell this to the public while unable to display that data is unethical and probably illegal.

I have asked for compensation for being tricked into buying this, but have not heard back from iNavX.
