Unusable. Can't connect to device. App crashes. Awful design means I can't connect my two devices even though they're already on the same WiFi (boat hotspot) instead need to use the plotter as hotspot and scan a QR code which fails to work and then leaves an incomplete device configured. Selecting the device crashes the app. All updates applied. Into the trash with it.

I was happy with it at first, however in order to sign into the app you must have an internet connection. Once signed in the connection is no longer needed. I had to reboot and then needed internet to get back in. Unacceptable if I depend on it. The good news. The chart download is very flexible and the charts are clear and can be zoomed in as much as you want. It offered contour lines as an option which made depths very clear. Routes are easy. Create a start & finish the app does the rest.

So, I've subscribed to premium as I have a lot of B&G equipment on my boat already. I don't think the app is at all ready for release yet. The first route I have tried to create takes me across land at the beginning, the summary says 189km and 19 hours for a route which is 8nm long and takes a little over an hour and a half and I cannot find any tide information anywhere. I tried leaving feedback in the app but just get the message 'something went wrong' 😕
