If you want to develop mobile apps then you'll need several things before you start. This is true of any type of development, however you especially need the following:

- Skills and knowledge – You'll need to know just how to code, and you'll also need to learn about design concepts like UX (User Experience) and Deniz Guney HCI (Human Computer Interaction).

- A computer – Needless to say! Ideally it must be a laptop/netbook that runs Windows or Mac OSX since most computers nowadays run one of these simple operating systems. However, if your skills are good enough then you may be able to produce an app on Linux as well.

- A smartphone – It's not necessary for developing apps, but it will certainly help because you can test them entirely on your device. If you don't have a smartphone then you could always use a friend's or a family group member's device.

- An IDE – A computer software development kit (or IDE - Integrated Development Environment) is necessary to create applications for Android, iOS and Windows Phone platforms. Popular IDEs include Xcode , Eclipse and Visual Studio.

- The developer license – You are able to develop apps without paying anything, but when you wish to publish them on app stores then you'll need to pay the annual fee that is currently $99 for Apple App Store and Google Play Developer Console. Several payment methods can be found, including credit cards, PayPal and wire transfer from your bank account.
