Currently the iPhone app looks like it's been designed with an eye to adding lots of features later. Except, we don't have them yet and it feels a little clunky to start the App and then have to request a security key by pressing a button when the only thing anyone wants to do is get a security key.

It's almost like getting a confirmation box when you log in saying "Are you sure you want to log in? [Yes/No]"... You just want to shout at it... "wth else would I be want ?!!?!?".

A much more user friendly interface would be for the security key number to automatically appear when the app is started (or restarted) on the main page with the countdown timer bar already running. Then put a button below it with "Refresh Key" or something similar. Then when the key has been displayed for it's 30secs, it's replaced by "-----------".

It would reduce the number of interactions required from the users and reduce it from 2 pages to 1 page.
