Latest Update

The latest update this month , June 2026, keeps crashing on my iPad. It seems fine on the phone. iPad and iPhone are both running the latest iOS.

Impossible to update Vulcan chart-plotter

Lousy app , confusing and often crashing .
B& G instruments are not updating from this App . When you connect to the instrument thru WiFi the updates are either not there or buried deep in a hellish menu when it should be obvious or happen automatically.
Try “ savy-navy “ as a chart plotter ; much better interface . This App reminds you why Apple is what it is and others such as B&G nowhere because of their lousy interface

It looks like the “ Triston” is only upgradable with files downloaded on a USB stick and you have to remove the instrument to access the connection
What a nightmare when it should be done over Bluetooth. Never again will I buy this junk . I guess uodates will not happen

Doesn’t work well on my iPhone

If I tap on the screen there’s in no option to Goto. I only get an option of creating a route which makes the point I have selected to goto the start point! Also when I turn the map to work out which direction my track is the mini compass turns the wrong way so it’s not showing North at all! I have no idea what’s it’s pointing to and it turns green or red or a shadow and means nothing at all! Very frustrating clunky and very hard to use. The app is not intuitive, and seems to do the opposite of what you would expect! (Goto, deleting old tracks and synching with my chartplotter) My map is cluttered with old tracks that I can’t seem to hide. They also cannot be deleted without going through the 3 dots instead of an option to directly delete which took 10 minutes to figure out. Why is it so difficult?? Even attempting to give feedback via the app doesn’t work as the send button gives me an unknown error and shades out the send button…! Gah!!

Needs some improvement

In the iOS app I dislike the following:-
1) The way it automatically zooms in and out after touching the overlay and function buttons, I would prefer it not keep zooming in and out.
2) despite map rotation the system goes back to map rotation, I would much prefer the ability to lock rotation until I decide otherwise.
3) I have depth set to metres, as a result the distance defaults to metres and kilometers, I want distance in nautical miles and depth in metres (the Zeus chart plotter allows this, so why not the app?).
4) the system often freezes after touching map overlay or plan or home.
I like the plan features, map overlays (though satellite imagery is not very clear in places).

Wonky kind of app

Bugs. Like in the weather layer the wind arrows are pointing backwards. Not very intuitive, hard to navigate. Otherwise outs ok. Hopefully a few more updates and it will be great.
