Yes. An app about poo. There’s no point pretending otherwise, because the screenshot tells its own story. A messy, smeared-all-over-the-screen… pooey story.

But wait, there is a serious message here. The app tells the tale of PooBarr, a bear getting first-hand knowledge of how different foods affect the digestive system.

One day he only eats bread, the next fruits’n’veg, then meat, spicy food, chocolate and greasy food. And every day he has a poo, which kids can spread using their fingers.

(Kids will love this. You know it. We know it.)

And on the seventh day, PooBarr eats “a little bit of everything”, which is the moral of the tale. “Perfect for sharing with your child as a gentle, pressure-free introduction to diet,” as developer Dave Sapien puts it.

Well worth a look, we think. PooBarr the Pooping Bear costs 69p on the App Store, and runs on iPhone, iPad and iPod touch.
