Do either of the above recommendations work with both windows and iOS? I have been using diviac. I like that it's cloud based and accessible from multiple platforms but fine the user inputs a bit awkward.
Fwiw, I just got a shearwater Perdix and it do s not appear that I can use their app on iOS.
If the perdix you got is the AI, then Divemate is the only one that i know that currently supports downloading to Android/IOS. I can then export the log to other programs. It does have a feature to export to dropbox.
