I just recently switched to 1Password and I'm really happy with it. I personally really dig the design, especially the mac app! However their iOS counterpart currently looks a little out of place, I'm 100% sure they are already working on a fantastic flat version, but I really wanted a fitting icon for my homescreen right now.

Edit:
And of course they released an update today... I might stick with my icon though, not a fan of theirs
