Black out – Getodo - Easy to-do and task list Review

I just downloaded this app but haven't been able to use it. Each time I try to add, or even to review the training the screen blacks out. No other app do I have this problem with, only this one. I believe it could be a good app but I can't tell since it doesn't allow me to do anything.
