This is a novelty app but one that also helps you learn something new. The concept is very simple. You just leave your iPhone on a hard surface with the app fired up then tap somewhere nearby and watch what happens.

It looks like something you'd find in a hospital, but it's one of those things that is very captivating once you've looked at it once. In fact, we completely lost track of time when we played with this app as we tried out different tap-based compositions - Top of the Peps had nothing on us during this review.
You've got the ability to pause the 'recording' of movement around the iPhone, in addition to looking at a colourful spectrum graph of what occurred in the three seconds prior to requesting that data.

We didn't quite understand what the chart was showing us, but it looked pretty nonetheless and it'll make you look über intelligent to anyone looking over your shoulder.

The app will monitor movement for 10 seconds and report back on the last three seconds of activity. You can then  upload that data in snazzy graph format to the web for all to see. Old friends will probably think you've changed career.

Remember how much fun you had playing Snap! as a child? You may not have known it at the time but you were actually learning and helping your brain to remember things that were the same. Memory Match takes that concept and plonks it onto the iPhone.

In addition to providing adults with a way of keeping their little grey cells alive and kicking, this app also delivers a great way of keeping children busy and, hopefully, quiet.

The app looks really simple but the game is actually quite difficult as each time you press an icon to reveal the character underneath you have to memorise the image and its position, unless you've successfully matched a pair, so that next time you find its partner you know which icon matches it.

Although be warned, when you flip the icons around to reveal the animal characters, it does have an associated tone, which can be annoying so we'd advise turning the sound off using the settings option.

There's a competitive element too as you have to try and get the highest score in the shortest amount of time possible And most people love a challenge.
