We've added a "My Check-Ins" page so you can see where you've been, a "Forgot Password" option to the login screen, and an email verification process to make sure you're really you. And, as always, we've squashed some of the bugs you've told us about.
Please note that we're still working on the bug that makes the home page freeze -- if that happens to you, just kill the app and restart it, and everything should work fine. Thanks for your patience as we figure this one out!
