Good reference but not sure Id boat with it.

Pro: Online charts paint very clear and have a nice clean look.
Con: For USA users they have a very non-USA feel. More of an IALA symbol mix on a ENC or IMRAY like chart. Nearly all functions are an in-app purchase.

Ill likely keep it for its clean look but continue to use other apps for boating.
