I'm giving it a one only because I found it very enjoyable to listen to two books but then I can't read anymore for a whole month. Being a new reader they make you wait 30 days before you can purchase more credits to read more. I find that very stupid, here I'm willing to pay more money to use there app and they tell me I can't for 30 days. Well I guess I'm going to spend my money on a different app instead.
