Just an fyi, when I try to sign in with google for your app I get the message: "The app is requesting access to sensitive info in your Google Account. Until the developer (*reka*kc*@gmail.com) verifies this app with Google, you shouldn't use it."
Ahh, sorry about that. It should be fixed in an hour, looks like we mixed the permissions. I just tried and confirmed other login methods work if you would like to try out.
