Boil an egg with your iPhone

This egg timer iPhone app was created by Crispin Porter + Bogusky Europe for Swedish sandwich spread Kalles Kaviar.

The idea behind the app is to assist users in boiling the perfect egg. It even puts together a playlist, that when finished, means your egg is ready.

It's clearly a hit with caviar/egg lovers as the app has already had more than 50,000 downloads and is the third most downloaded in the free app section in the Swedish iTunes AppStore.
