How well does it work with iOS/Android (I know OP didn't ask about mobile apps, but I'm curious)? The page says that there are apps available, but those seem to be the kind of apps that are a pain to install.

I tried the (or one) android app and it was fairly good, though I'm back with keepass ATM as it ultimately has the best cross-platform support (windows).

I've been relatively happy with SplashID, and while they're pushing their online cloud offering, you can also use it offline or synchronize just on your local network. (Looks like the version without sync is entirely free.) Works on Mac, Windows, iPhone, Android, and I've been using it since the Palm OS days.

What do you mean by keepass formats aren't aging well?

1Password. Besides personal positive experience, I've never heard a bad word about it. Solid piece of software.

There was a brief report of metadata being stored in the plain: https://myers.io/2015/10/22/1password-leaks-your-data/

There's a rebuttal from AgileBits: https://blog.agilebits.com/2015/10/19/when-a-leak-isnt-a-lea...

Yah, I guess I should't have said that I've never heard a bad word about it, because I did follow that storyline closely. Pretty much, just don't use the old .agilebits keychain and instead use .opvault

whats your issue with keepassx ? Genuine question. I use it and it works well for a free app.

I've been using keypassx for years, but I'm seeing a lot of threads where folks imply that there are systemic issues with the product.

I'm a power user of this type of tool, but I lack the qualification to actually judge crypto quality myself.

iCloud Keychain can be used offline (although it doesn't work with other platforms). https://support.apple.com/en-us/HT204085
