iAppalooza: What Apps Couldn't You Live Without?

Over the coming weeks we're going to be going app-crazy, looking at some of our favourite apps from Apple's behemoth App Store. But with over 250,000 apps available across 20 different categories, chances are we've missed a few. So help us find them!

We want to know: what are your favourite apps on the App Store? We're looking for apps across a variety of categories, so not just games and entertainment. And we all know everybody loves Angry Birds - we want you to help us find the hidden gems, buried away in the darkest nether regions of the app store, rather than the biggest and brightest programs around.

Help us out by telling what apps and why in the comments below.
