Though the Blackberry and the Symbian are the current leaders in terms of smartphone sales, the iPhone is undoubtedly king when it comes to applications. In 2008, Apple opened an online site called the App Store. From the beginning the site gave iPhone users the ability to download both free and paid applications.
What exactly are cell phone apps ? Well, really they are nothing more than mini computer programmes that can be downloaded directly to your mobile device. Presently, the most popular applications or apps are mobile games. These games can be downloaded free of charge or for a small fee for most devices.
But getting back to the App Store, less than a year and a half after it opened its virtual doors the company celebrated its one billionth application download. Yes, that’s billion with a "b!" As we mentioned, even though mobile apps are still the most popular and are downloaded primarily by younger users, there are many useful applications that have been brought to the market.
Probably the most popular non gaming applications are called office apps. These applications include programmes that help office workers organise and proofread important files over their phones when they are away from their computers as well as apps that allow them to keep in contact with important clients.
The price of these applications ranges from free all the way up to a few hundred pounds for some of the more advanced apps.
