Can't even get past the login screen – 21-Day Meditation Experience Review

I click 'login with email' and a white, blank screen pops up and nothing loads. I tried that multiple times to no avail. Then I tried logging in with Google+. The app crashed the first time, so I reopened and tried it again, and was able to login and accept the app. After that... Same white, blank screen. What's the point of offering the app if it can't even be used?
