Ratings and Reviews
Very useful program
This is an excellent program
The extraordinary variety of configurations and capabilities can initially be confusing, but you can easily set it up to your preferences. I use inexpensive vmh mbtiles for charts and it works well, although these charts do need quite a lot of storage space. The developer is very quick to help and had corrected a minor bug I found very fast! Setting up uk harmonics for tides and currents was not particularly easy, but the (huge) manual explained it all.
Confusing
I use marine navigation & weather apps at lot both for leisure and work. This app does a lot potentially, but is so difficult to use with a very unfriendly interface. Unless you are committed to an extremely long learning curve, you may be better looking elsewhere .
