Unfortunately the Apple downloaded app seems to be wonky. The Play Store app works almost perfectly.BYC does have an app, but personally I hate using it! (Sorry, staff). Instead I do what @KikisGirls mentioned.....I googled Back Yard Chickens, and when I got there I just told my phone (and my iPads) to put it on my home screen. By doing that, then turning my device sideways to landscape mode, it functions just like my computer. One tap and I'm here. I'm on my iPad right now.
