For logging into sites like banking or message boards which you prefer? I just bought 1password and its great but I want to know since it has its own browser and it automatically fills in my details do I need the mobile app anymore?
Of course not every site has a mobile app.
For important sites that I frequent, I prefer the mobile app, even if the app is clunky. Of course, many of these sites require password, so login experience isn't quite as easy as 1Password. I would like 1Password to evolve into OAuth-like service, where mobile apps can request 1Password to return login info for easier login.
Furthermore, 1Password often doesn't do a good job resolving duplicates.
FYI, iOS 7 added iCloud Syncing, which works well when it does work. But IMO, Safari doesn't do a good enough job detecting login form, often failing me to prompt to save the user ID and password.
