If you've just bought yourself a new iPad, you're going to want to start downloading the best apps straight away.
It's the Apps that really set iOS apart from other platforms - there are far more apps available for the iPad than any other tablet. So which which ones are worth your cash? And which are the best free apps?
Luckily for you we've tested thousands of the best iPad apps so that you don't have to.
So read on for our best-in-class apps for each major category, followed by some more specific lists of the best free and paid for apps and games.

Apple's iWork apps have been praised for their look and feel, but many actually prefer Quickoffice Pro HD. It dispenses with Pages', Numbers' and Keynote's visual clutter to present a clean, professional interface, while beating Apple to the cut by already fully integrating cloud synchronisation courtesy of Google Docs.
Even if astronomy's not your thing, you can't fail to be impressed by Star Walk. Point it at the sky, and using the iPad's digital compass you'll see a virtual starscape on your screen. It gets even better when you start move around - you'll see that the view pans with you, highlighting what constellations you should be able to make out.
While iOS is packed with useful features, itdoesn't offer native support for many popular video formats, and this is where the AVPlayerHD app comes into play.

Rather than having ahefty one-off price, the new Jamie's Recipes is free, but contains only a 10-recipe sample pack - you have to buy more packs as In-App Purchases of around £1.49. We're loving the attention to detail - for example, ingredients can be added to a shopping list, which you can email to yourself or a loved one to pick up on the way home.
GarageBand turns your iPad into a collection of Touch Instruments and a full-featured recording studio — so you can make music anywhere you go.

Navfree turns your iPad into a fill-blown satnav device, offering turn-by-turn directions, voice and on-screen instructions, offline map use and address search and live search via Google and Microsoft Bing, among many other features. And it's completely free.
While some hold up Pulse as the best way to access RSS feeds - stripped-down, automatically refreshed website content that you usually subscribe to for free - it's a little too lightweight for us. It's fine if you only have a dozen or so feeds coming in, but if you follow a lot more than that, Reeder is the app for you.
If there's an iOS app that comes close to offering the kind of editing facilities that are available in a Mac OS X or Windows application, then it's this one, Filterstorm. For starters, it can import and process images in raw format. Add to that a host of editing tools, such as curves manipulation, colour correction, noise reduction, sharpening and vignetting, and you can see already that there's plenty here for photographers to get excited about - and it doesn't stop there.
You can create multiple notebooks, and stack and arrange them on a shelf. Each notebook has a default paper style - lined, squared, and more - but you can mix paper types in one book; yay! Better still, you can import your own templates. There's no handwriting recognition, and the option to type as well as hand-write would be nice, but even so: superb.
Find out how much vitamin C is in a bowl of ice cream. Learn what European country has the fourth largest population of children. Compute solutions to difficult trig and calculus problems.

It may sound like stating the obvious, but this is clearly designed for the iPad from the ground up. It does more than just take advantage of the big screen and gesture recognition: other iPad features including the cameras and location services have been thoughtfully integrated as well.
There's only one way to watch Sky Sports on your iOS device, and that's using the brand new Sky Go app. It replaces the much-maligned Mobile TV app, which had the cheek to demand you pay money for it, even if you were already paying a monthly fee for Sky TV and Sky Player. Providing you're a Sky Sports subscriber, you have access to all 4 Sky Sports channels, as well as ESPN, Sky One and more.
If, like us, you were amazed by the desktop version of Google Earth when you first used it, you'll love the iOS version. The iPad's Multi-Touch interface is the perfect way to navigate the planet, allowing you to fluidly roll from one place to the next, pinching and swiping your way from one amazing place to the next.
