Totally ????

Unless you have microscopic eye; u donโ€™t buy PRO u will sail blind

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.

Open sea map

iOS 16.1.2. Itโ€™s not usable. Crashes when I do anything.

On a Baltic Cruise

I am a retired boat builder and used this free chart on a Baltic Cruise so I knew exactly were the ship was. The resolution and accuracy was excellent, better then on the ships television version. To make it work well when out of internet I found it worth opening the chart and zooming into areas I was most interested in such as harbours to see buoys traffic separation zones etc. Whilst I had internet as It builds up the Cache, in my case this amounted to 23.8 mb.

Useful

This is free - and does not replace conventional chars and chartplotters. It gives buoyage but not depths.

I find it useful for planning when away from my boat and my charts. Afloat and where there is a phone signal, I find it helpful to have a quick visual position - I have a GPS, paper charts but no chart plotter.

Sure, it doesnโ€™t replace charts. But I find it useful.

Utter crap!

This is not a chart. It cannot be used for any navigation. It would be better to spend .99p in a second hand book store and navigate with a world atlas. Save your money!!!!!!

Sluggish 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.

Not happy

After paying for the pro version to get the weather layers, no weather to be seen.

Puzzled!

Like the previous reviewer, all I am seeing is road mapping and 'blue' sea. Have searched online for info and I am not finding much! Help!

Not very helpful

Can't search with lat and long coordinates, just seems to be a road map with the sea coloured in.
