A couple of features I really like on the Navionics app:
1) The community; it is possible to correct / amend the charts, Navionics will verify the the corrections and post them
2) Search function; marina phone numbers as well as other amenities are available, such as restaurants. This can also be added to through the community.
I would not use it for "serious" navigation.
