After a few moments of use, the screen goes completely white on my iPhone 4S. The only way to get the app to work is to power the phone off, power it back on, and restart the app.
This has happened twice, just a few moments after I installed the app.
If it hadnt been for that, the app looked pretty good. I hope they get this resolved soon!
