TOP 10 FREE USEFUL APPS FOR IPHONE

There are now hundreds of  apps available for your iPhone 5S, iPhone 5C, iPod touch and iPad, and, surprisingly, all of the best are free.

The following list showcases our pick of the top 10 best free iPhone apps, and includes iPhone applications for social networking, travel, news, photography, productivity and more.

Most of these apps are also suitable for the iPod touch.

1. PhotoSynth

We did a bit of a double-take on seeing Microsoft's name attached to this, not least given the lack of a price-tag. But PhotoSynth is a really great panorama app; it's user-friendly and fun to use, especially when watching your panoramas take shape while you capture them. (The iOS Camera app also has a panorama mode, but PhotoSynth's more flexible and works with older devices.)

2. RunKeeper

The prospect of Nike+ but better and for free might sound unlikely, but that's what RunKeeper provides. Previously split into 'pro' and 'free' versions, the developer now generously includes all the features in one free app.

That means you can spend no money, yet use your iPhone's GPS capabilities to track your jogging and cycling routes, and examine mapping and details of your pace and calories burned. Activities can be shared online, and treadmill runs and other exercise details can be entered manually.

3. National Rail Enquiries

For anyone commuting by train, National Rail Enquiries is a handy app to have installed. There's journey planning, timetables and a location-aware 'next train home' option, along with progress tracking, so you can see when a train's likely to show up. It's not as usable nor as pretty as UK Train Times, but it is broadly similar - and five quid cheaper.

4. TonePad

Virtual pianos and guitars are all very well, but purely digital musical toys are more suited to Apple handhelds. TonePad is the best of them, using a grid-based interface that enables you to turn notes on and off and compose pleasing and harmonious loops; your creations can be edited, saved and uploaded to share with other users.

5. Wikipanion

The Wikipedia website works fine on iPhones, but a dedicated app is a better bet. Wikipanion is a freebie which gives you quick access to article sections, in-article search, viewing options, bookmarking, and the ability to tweet about whatever odd fact you've just unearthed. Also, wonderfully, there are no ads.

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. Around Me

Around Me figures out where you are and lists local stuff - banks, bars, petrol stations and, er, Apple Retail Stores. The app's reliance on Google Maps info means there are gaps, but it's nonetheless handy to have installed when in unfamiliar surroundings, and the 'augmented reality' landscape mode is amusing, if flaky.

8. XE Currency

XE Currency is a fine example of an app that does what it needs to, without fuss. You configure a list of currencies, and it shows current conversion rates. Double-tap a currency to set its base rate or to define values for custom conversions.

9. Zoopla Property Search

There are loads of property search apps on the App Store, but Zoopla is the best of them. Its listings are comprehensive and there's also local market data, including sale prices and estimates on market value. Naturally, the app is also location-aware, meaning it can rapidly find properties nearby or close to a user-defined post code.

10. Skyscanner

Skyscanner's a great website, which enables you to punch in airports and find out the cheapest way of getting from A to B. The Skyscanner app is the same, but it's on your device and with a spiffy AI. Well worth a download, even if only to check flights for an upcoming holiday.
