I would love to give this app 5 stars but I think it's ridiculous that even when you purchase stickers they still give you duplicates over and over never giving you new stickers. And when you move up on achievement you still get duplicates. They don't give stickers often. I've spent real money and still no new stickers. I wish they were more giving when you make achievements or actually buying them. They just take your money and give you hardly anything in return. Sorry but this app not fair
