Inoperative on iPad 4

Its difficult to write a review because if your nickname has been used by others you must start over again completely. The Write a Review does not save your message for a try at using a different Nickname.
This app doesnt work on my iPad 4 with IOS 8.4.1
It opens briefly then closes again.
Wish it did work!
