FAQ for Development of Mobile Application:

I have been producing software for over 3.5+ years and am now pleased to offer contract development services for the iPhone, iPad, iPod Touch and Android.

There is currently an audience of over 100 million iPhone and iPod Touch users.

Many of my clients have asked below questions and I am putting that on my profile so it will help you a lot if this is your first mobile application.

Q: Who is responsible for the interaction with Apple?
I can take full charge of this aspect on your behalf although if you wish to sell the app under your own personal or company name we have to undertake some relevant documentation to cover this. However, I am well versed in these processes and will guide you smoothly through the whole procedure.
Likewise, regarding the Apple App Store requirements for approval, you need have no concerns as we will liaise on your behalf with Apple representatives to ensure the application reaches the App Store in the shortest possible time.

Q: Who owns the idea - and the source code?
Mostly in all the cases you own the source code and copyrights unless you want me look for alternatives or joint ventures.

Q: Are you able to write the scope pertaining to the project?
Of course. Not problem at all with this area. I am experienced, logically, in writing a completely functional scope for your given project. Even more, I can offer you and a technical breakdown if you are interested in this aspect of the app development.
I would normally present this to you in PDF format. However, if you wish to re-brand to your company's profile with a view to presenting to your clients I can easily set you up with an InDesign CS file that will allow you to do this.
