wheres the chart data?
had high hopes for open crowd sourced charting, this isnt it. for marine navigation, even google streetmaps on sat view has more detail. willing to be told im wrong, but i deleted it after 15 minutes.
United StatesOpen sea map
iOS 16.1.2. It’s not usable. Crashes when I do anything.
United StatesSluggish and lacking detail
I suppose we have to buy charts to see any detail and if I'm going to do that, might as well use Garmin. Views are slow and buggy to load when you zoom.
United StatesVery good and useful
This is a very well designed and useful App. The map zoom feature is especially helpful for reading small details. Overall excellent. Get the Pro version for added features. There are some missing features I hope to see added: speed over ground; continuously updated position; track.
United StatesPurchase app that dose not work! Can you refund my money!
I just purchase the plot seamap and it dose not work! I wold like a refund please. You guys need to work on this before you sell this app any more.
United StatesNo depth info ... Useless
This app provides attractive maps, but I cannot get it to display the depth of the water. Nice land map, but useless on the water.
United StatesGreat if pack more features
This is the best I can find for an app that's free and usable. But unfortunately for what I need, it just need a little more. All I hope for is that i can bookmark an location and be able to remove them individually. This app can't even do that. I wish there is that feature, then would at least be a 4 star.
