Anyone who’s ever tired to entertain a small child knows that it’s often hard to get them to sit in one place for any substantial period of time. While the first iPhone had its fair share of distraction value, that ante has been upped by LateNiteSoft’s £3.49 Sketches, which did a pretty successful job of amusing a three-year-old and 18-month-old for a solid 15 minutes - no mean feat.

Sketches is one-part Etch-a-Sketch, one part Comic Life. As its name suggests, the program lets you create your own drawing masterpieces on your iPhone - or, alternatively, while away your hours by drawing handlebar mustaches on your friends’ faces.

When you first launch Sketches, it displays its main screen, a gallery of existing drawings fashioned to look like a corkboard. The first several images make up a brief tutorial that explain how to use Sketches’s various features; tapping any of them will zoom them into a fullscreen view.

While the app is pretty straightforward, the tutorial did clue me into the fact that you have to use the two-finger pinch method to place (and resize) clip art. Once you know that's how it works, it’s simple enough to use.

After you’re done with the tutorial, you can create your own drawing by tapping the Plus (+) button on the main screen; you’ll be given a blank canvas on which you can express your artistic genius. You can draw lines of various colours and thicknesses by tapping the Crayon tool and just drawing with your finger on the screen.
