My kids love this app. I looked at the other packs that you can purchase and I was interested in maybe purchasing one. The issue is I refuse to purchase something that doesn't disclose a price. Makes a person uneasy on this app and other apps you might have.

Camera no longer works

My niece used to love playing with this app, and I would have rated it 5 stars, but the camera in the app has randomly stopped working. Now, whenever you press it, the app immediately crashes and has to be reopened.

Aside from recording her voice and roaring, the camera was mainly what she liked to play with. If this can be fixed, I will amend my rating. I have an iPad Air and am running iOS 8.1. I had the issue before updating to the latest iOS.

Issues with the sound. I have turned my phone off and back on and still no sound. I have also uninstalled and reinstalled the app and still no sound. Considering uninstalling for good if this cannot be corrected.
