I am using an SDK, called Ozeki VoIP SIP SDK. There are sample programs that describe how to develop mobile apps for various mobile OS platforms like iOS, Android, Windows Phone. If you are interested have a look at the followings: http://www.voip-sip-sdk.com/p_449-vo...orms-voip.html
The best way to get your mobile app idea realized is you hire iPhone developers, and the best mode to get this work done is, of course, through offshore outsource development. iPhone apps have fascinated a big user-group. They are those serious users who hardly think about other smart phones.
There are many tools available to create mobile applications. In my knowledge, wordpress is the best platform for creating mobile website. It has lots of plug-ins and themes that make your website fully functioning and attractive.
While searching I found an online tutorial which is very simple to understand and read. You can check out http://www.openwebsitetutorials.com/...obile-website/, where I learned about how to make a mobile website. This tutorial is very helpful for newbies.
If you already have a website, and are just looking for a way to cater to your mobile-device-using visitors - and not spend an arm and a leg - you can simply create a mobile version of your site, which would then be dynamically served via sniffing. To do so easily for free you can try GinWiz.com.
Each platform is unique and exhibits different features, capabilities and behavior. But then, multi-platform apps are truly “in” today, so you as the developer, need to find solutions to develop the best cross-formatted apps, without emptying up all your resources on developing for just a couple of platforms at one time.
Fortunately for you, there are some really great multi-platform developer tools in the market today; using which you can easily achieve your aim. Here is a list of the top 5 dev tools for cross-formatting mobile applications.
I think it depends on what kind of platform you would like to choose. For IPhone app, you need to have some basic knowledge about the Objective C programming language to be use in Xcode IDE and for an android app you need to have better knowledge about the Core JAVA Programming which is created with Eclipse Tool using Android SDK Plugin.
Learn from the google easily.. I hope you could have a better information to create an app. You can prefer the some mobile app development company. I hope they will help you out.
