Room for improvements
The app is okay. I really like the ability to import keys via AirDrop or iTunes from a safety perspective this is the only acceptable way to do this.
However I am really missing some features. I think the app should provide the ability to paste a password from clipboard while using a private key. It would improve the usability a lot and it would also be a good protection against key loggers.
If the developer thinks about implementing this he should also consider some kind of a password manager integration. The 1Password integration of the mobile Safari browser is a good example for what I am having in mind.
