I have this on 2 devices and Ive never had problem with downloading or stability. It is a sweet, lightly educational app for 2-6 year olds with tons of features for free: animals, educational videos, games and a fun and fluid sticker book with savable images. YES you have to pay for additional sections... but lets get real: its $.99 per section, currently $2 total for a ton of content. You can afford it - few if any $2 toys will generate as much enjoyment and learning.
