I went for a 8 days trip to the Maldives on a liveaboard. We barely had any internet the whole week. The Gramin Dive app was completely useless because it asked me to login. I understand that some features are disabled and that's fine, but not even being to login and see and edit my dives? This is absolutely ridiculous for a dive app where by definition, you are far from civilization. Note that I was loged in the app before going offline so it should just work. Garmin Connect is able to do that, why not Garmin Dive? The whole app is basically useless because of this and I cannot recommend Garmin as a dive computer unfortunately.
