If only the app was actually worth it. I tried it out, and so far:
There's a persistent notification that never goes away, even after you tell Android not to allow notifications from the app (no idea how they did that, never seen another app do that)
I haven't gotten past the signup yet, even though I got the email. Seems that the signup process resets if you switch out of the app. Too bad if you want to use Lastpass to generate a password.
After I gave up and wrote the password down, it decided that I hadn't gotten the approve email. No amount of clearing data or retrying would convince it otherwise.
