Hi, the iOS 7 facelift looks like it might end up great, you've still got a lot of challenges ahead but your team is great and you will get there. There are a few thing I'd like to point out that looked great before.
For example the unlock animation looked better before, I preferred the unlock where both doors went to the sides (current version) instead of them going up and down (iOS 7 version).
On the other hand please please take away some of the white, my iPad looks like a kindle since iOS 7 was released, each and every app decided to take away all the skeumorphic and in the process take away all of the color, 1Password had great gradients of colors in the current version, why take it all away and just add white? (I know you've taken some of it away with the latest betas but still).
Finally it would also be awesome if in the 'Categories' section you had a search bar on the top and you could start searching without having to select the category and then search, it's one step less needed to search for a password.
I hope I have helped, 1Password is in my iPad, iPhone and Macs dock, which means it's in my top 4 apps!
