Jamie Oliver, never far from the cutting edge of tech, has launched an app for the iPhone and iPod touch.

"20 Minute Meals" offers "50 delicious new recipes, gorgeous step-by-step photography throughout and 21 exclusive Jamie Oliver videos with cooking tips, hints and techniques".

There's "world-firsts", including voice-prompts from the Oliver, an interactive shopping list sorted by supermarket aisle, and the ability to suggest a random recipe with a quick shake of the phone.

"These days people are so busy and always on-the-go but they're rarely without their phones", said Jamie.

"When I set to work on this iPhone app, I wanted to make sure I gave people everything they would need to help them create great tasting, homemade meals in around 20 minutes – that’s less time than it would take to order and receive a delivered meal and yours will taste better".

20 Minute Meals is available now on the iTunes App Store worldwide for £4.99, $7.99 or 5.99 euros.
