Search function doesn't work, I inputted my cities name and nothing happened. I also could not choose between explore button and Marina button, the Marina button was highlighted but it made no difference. I also found the maps all twisted up and mixed up so you had places in Canada right next to places in the US that do not border Canada. I am totally disappointed and will remove it, I definitely am not going to spend any money for it!

Great app. I use it for kayak touring the great lakes. It also shows info on my local lakes. I find it easy to use as a non-techy person. No trouble using it or installing it. I really like the wind and wave forecast features, and i use them most often. Also, the ability to look up nautical symbols is very cool. (Object query feature)

Every year at renewal time I have to contact support to get a new registration key and it never works. I have to go back and forth with them to get it to work. what a pain. When the app works most of the time it works well. Sometime the track will turn off during a trip and you would not know it happens. This app makes a good backup plan for boaters.
