How long to create an app?

[Gustavo]

So I was wondering how long do it take to create an iPhone app, kind of like Instagram, kik, etc.. How long would it take one person to develop it? Thanks

For an experienced developer, you could get a prototype done in a few weeks. Without having programming knowledge, it would take much longer. You would need to be familiar with Objective-C and Apple's development tools for iOS, or with web development tools and using a system like PhoneGap. The apps themselves are pretty simple- they connect to a backend web service, send it authentication, and ask for pictures. The harder part is doing the backend work of storing the pictures and doing the account authentication, especially doing it in such a way that you could easily scale up to millions of users. Modern cloud systems like Microsoft Azure and Amazon Web Services certainly make this easier, but it still takes a lot of know-how to get it right.
