How could they screw the app up so bad?

Ive only had my Echo for a day now and Im impressed with the device itself but this app is pretty shoddy work for a company like Amazon. It constantly locks up or fails to connect to the device. It also asks me to log back into my Amazon account constantly. I find myself having to force quit the app and start over almost every time I need to use it. Doesnt Amazon do any QA?
