We've put together a selection of the best apps exclusive to Apple handsets.
Sync your calendar
CalenGoo syncs with your Google Calendar and even has a similar look. Other neat features include the ability to invite people to events, plus an integrated task list.
Browse in style
Re-creating a desktop browser on the iPhone's screen, Atomic Web Browser has tabs, ad blocking, multitouch gestures, a passcode lock, Facebook/Twitter integration, and more.
Price: Free basic version, 59p premium version
Manage your reading
Through Instapaper you can save web articles you browsed on your iPhone for later reading, using a browser bookmarklet. The Instapaper website reformats your saved articles (sans Flash ads and clutter) for quick reading on the desktop.
The WolframAlpha app is the ultimate tool for know-it-alls. Ask questions in sentence form, and the semantic search engine returns the answer. Though it can already answer just about any question you ask, the creators are constantly updating it with new information, making it an ideal companion for pub trivia night.
Discover healthful recipes
In the Whole Foods app you can find creative recipes using what you have on hand, and see them in an easy-to-read interface.
Cook with a pro
The How to Cook Everything app, based on Mark Bittman's book of the same name, gives you access to 2000 recipes, as well as to no-nonsense cooking advice, how-to illustrations, ingredient information, built-in timers, and organised shopping lists.
Utilities and timesavers
Watch your calories
For keeping track of your caloric intake, Quikka Calorie Pro is a handy tool. The app tells you exactly what you're eating during the day, and it gives you a chance to enter your food intake on the go, so that you don't forget to do so later.
Add a phone line
SecondLine brings a second line to your phone (with a special number). Calls on that line connect as free or cheap VoIP calls over a Wi-Fi or 3G data connection, but they can move to a mobile network (which costs you plan minutes) when such connections are unavailable.
Never forget passwords
To maintain your usernames and passwords on your iPhone in one place, try 1Password. The mobile app syncs with the desktop version, as well. If you wish, you can use it to store other personal information, too, such as your National Insurance number and credit card numbers.
Price: £5.99 basic version, £8.99 premium version
Locate Wi-Fi anywhere
A must-have for travelers, Wi-Fi Finder is a directory of paid and free Wi-Fi hotspots in over 280,000 locations in 140 countries. You can filter results by provider or by location (restaurant, café, and so on).
Find your way
The TomTom app turns your phone into a GPS navigation device with turn-by-turn directions. Maps and routes are stored in your phone's memory, so updating maps and changing routes happens quickly and without requiring a wireless network connection.
