To begin with, the very main thing that you need to do is know clearly what kind of app you want. Do you have a lot of content to be used or do you just want a simple, easy-to-use kind of an app? After you are clear on this you will learn about the speed and cost that it will be developed at. Based on the idea the layout for all the functions can be designed. You will either need to hire a programmer that knows his/her way around the app functionalities or give in your sufficient time to understand what each click can do and the number of clicks that are there even in the simplest of apps.
