And now for something completely different, Ladies and Gentlemen: an iPhone app that tells you how many calories there are in your chicken and salad sandwich, or your macaroni cheese, or your handful of dried apricots. You snap a picture, send it off to the magical world of Meal Snap, and they respond giving you an approximation of how many calories it contains.

They don’t enlighten us as to exactly how they calculate the calories in your bowl of porridge or roast beef and Yorkshire pudding. It’s all down to magic. And the photo from your iPhone.

Did I ever think that there were so many uses for an iPhone camera. Nope! Will I be using it myself? Not a hope in hell. I’ve never counted a calorie in my life. But I bet I know some people who’ll be falling over themselves to try it out.

£1.79 or $2.99 from the App Store.
