This app sucks
The app constantly crashes. I delete and reinstall and still it crashes. Fix your garbage app.
Very disappointed
My immediate reaction after using the app is that its display of depth has weird fonts that make it impossible to read or be confident in planning routes. Also, basic navigation and route planning is extremely glitchy. I don’t think I’d trust this at all. I’ll play with a little more, but highly unlikely to depend on it, or pay for it.

Very buggy App
I wish I could’ve shared this information through support, but there is no support communication option for the companion app according to the knowledge base and any information posted in the app support link provided here. The app is extremely buggy the icon a circle that represents my position often just doesn’t show up every time you touch the screen. Often when touching the screen to zoom or move it thinks you’re putting a mark down. Most of the function in the UI is just not well planned and up to par with so many other Apple apps. I am hopeful that B&G will make a proper investment and get this app up to snuff.

Disappointed
Just upgraded at 70$/year and not impressed. It crashes you can’t see forecasted weather along the route based on your plan. Basic features that an App from B&G should have. Other apps made by private people are much better. A lot of issues with the GPS signals while other apps run at the same time don’t have. I wish I could be reimbursed. Can you hear me??? The worst upgrade I have ever done

Crash all the time
The app crash all the time on iPhone 16 iOS 26.5 !
App on new iPad
Can’t even open the app on my iPad without it crashing over and over. Very dangerous. First my Zeus 3 plotters (3 of them) jam then the app crashes on the back up iPad. I’ve spent a fortune on this product and expected good functionality.
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.
Creating routes
Easy enough to use and interface with B&G but at times very difficult to find destinations. For example try routing to Messina in west Sicily. It routes automatically to Milazzo.
Sync Function with Zues S
Sync function very occasionally works but invariably says “fail”. Even the feedback option in the App does not present well or work. Come on guys, please sort this out.🙏 This is basic functionality that hasn’t worked since I bought my Zues S chartplotter.
Erreur, identification, multisupport
Erreur identification avec le iPad et pourtant j’ai bien mentionné mon adresse mail et mon mot de passe. Ce qui est très curieux, c’est qu’il fonctionne très bien sur mon téléphone portable. Android Samsung S24FE,
Frustrating
Refused to connect with my plotter and kept repeating error screen until rebooting iPad.
Bonne application mais
Application très pratique pour préparer et transférer les navigations vers le traceur.
Seulement malgré l’avertissement de mise à jours de cartes disponibles, impossible d’effectuer celles-ci. Donc seul solution suppression des cartes à nouveau création, dommage.

Poor UI, poor implementation
Never syncs with my chart plotter and riddled with bugs
No way to get app support
Latest app is better, but the charts default to meters and not feet and can’t be changed. Also, there’s no way to get help on the app. Help and feedback simply send you to the BNG master website, which has all kinds of other stuff.
Won’t sync with zeus3s
No way to contact support - B&G support say they have nothing to do with this app- is this a scam?
I can’t trust this for navigation
Inordinate number of crashes. Start the app: Crashes. Over and over. Then a message says something about downloading offline maps; crashes again as soon as I say yes. Synchronise with onboard Zeus S chart plotter… good luck! Maybe a month later today’s track will sync. I just updated the software on my Zeus S chart plotter…. only to find that the ‘race’ options have disappeared. B&G is now a toy system for inshore power boats.
