Remember those cardboard books with big animal pictures you read with your baby? The ones you use to tempt your toddler to imitate the sound of a lion? Or a cat? Or a cow?

GRoink is exactly that for your iPhone, iPod Touch or iPad. Captivating images, spot-on sound and attention-grabbing animation as you flip through animal pictures and tap the screen to hear the lion roar...

Download GRoink for free from the App store. If you like it, you can download all images for .99$ only.
