Ummmm? – self timer auto Camera with zoom, speech & fx Review

This doesn't quite work am I doing it wrong? The only thing it shows is a dark screen with little things you can do with your pictures at the bottom. I got to make it count down but still only darkness. This app would totally be helpful with taking pictures if it would work! If your also having trouble with this or think it fine or even knows how to fix it tell me!!
