The world's biggest social network brings a great experience to the iPhone and andriod, but nonetheless still enables you to access your contacts, feeds and other important information. This sense of focus makes it in many ways superior to using Facebook in a desktop browser.

2. Pulse

RSS has a reputation for being a rather dry technology, feeding you dull lists of headlines. Pulse flips RSS on its head, providing streams of feeds that grab your eye with photographs. It's perhaps not for the hardcore RSS crowd, but if you follow a small number of feeds, it's a great choice.

3. Dropbox

Plenty of apps exist for transferring content between your computer and your device, but Dropbox is free and easier to use than most of its contemporaries. Dump files you want to sync in a folder on your computer and Dropbox for your device will enable you to access them, download them for offline viewing, and, in many cases, view them.

4. Skype

FaceTime is a great alternative to standard voice calls, but it's no good if you're trying to contact someone without a Mac or compatible iOS device. Therefore, Skype remains an essential download. The interface is simple and usable, enabling anyone with a Skype account to make free calls to other Skype users and cheap calls to anywhere in the world. If you're on Pay and Go, this is particularly handy, but the app also enables iPod touch users to utilise their devices for calls.














5. Twitter

The official Twitter app might lack some of the features found in the likes ofTweetbot, but it does provide a sleek and simple means of using the service. It also directly mirrors the latest navigational scheme on the Twitter website.

6. Evernote

Clients to access the popular Evernote service for storing notes and ideas online are available for so many platforms that we half expect a ZX Spectrum app to be announced tomorrow. On the iPhone, Evernote is efficient and usable, enabling you to rapidly scan your notes and also create new ones.

7. Adobe Photoshop Express

If you're looking for Photoshop-style power, Photoshop Express won't impress. However, if you're after a quick, free, highly usable tool for making edits to your iPhone photos, Adobe's app is ideal. Use it for cropping, straightening, exposure adjustments, colour effects, sharpening and more.

8. Shazam

Shazam is an app that feels like magic when you first use it. It's deceptively simple—hold your iPhone near to a music source, and wait while the app listens and tells you what track is playing. But the sheer technology behind this simplicity is mind-boggling, and while Shazam doesn't always guess right, it's worth a download.

9. Flipboard

It would be a hard ask to expect the Flipboard experience on the iPhone and iPod touch to match that of the iPad version, but it nonetheless has a good go, transforming your favourite feeds and news sources into a tiny, beautiful digital magazine.

10. Sums

Although we're fond of PCalc, mentioned elsewhere in this selection of apps, there's something really lovely about Sums. The visual design feels sleek and modern, with a handy tape-style path of totals displayed; even better, operations are performed via gestures. This is a bit weird at first, but it soon becomes second-nature.
