4 stars: I ve tried 4 or 5 apps, all asking for premium after a short trial or limiting usability. Free version is good to plan a trip, having weather is same window is Very helpfull. do give this app a try, its easy to learn and you will be satisfied. older sailor here. Dev: i would like app to allow manual disengagement of gps location. This way make navigation plans without gps battery consumption.
5 stars: Best free navigation app available. Easy to use and read. Has all the features I need. Tried after getting frustrated with Navionics.
3 stars: So far, I have been at home messing around, plotting courses. I'm eager to see how it works on the water if I don't have an internet connection. I will be testing it in the U.P. of Michigan.
5 stars: this is a wonderful navigation tool. use it along with my onboard navigational system.
4 stars: so far i am very impressed with this app As retired skipper I'm used to quite expensive apps and charts so this is realy good, especially for just fun planning and occasioal trips. thanks c-maps
5 stars: i have small cabin boat in VANUATU ,used for fishing and family holidays. used a simple GPS/SOUNDER but this app gives me a basic chart plotter and the ability to create marks/waypoints , Extremely useful for fishing and plotting inter island trips. pretty simple to use . Very Impressed. i use a Navico autopilot.
5 stars: excellent app used it to cross the channel from medway to ramsgate and then ramsgate to dunkirk...
