The advantage when you Hire cross platform developer company like Hyperlink InfoSystem is that you can create one app then use cross platform technologies so that the same app can be deployed on different mobile device platforms. This is good from a business perspective because you are essentially using the same skeleton of the app but fleshing it out for use on the different platforms. This is also good news for cross platform developers because more businesses will want their special services as word gets around of their successful cross platform projects.
When you consider cross platform applications, you can actually choose which mobile device platforms you want to amend your app for. For example, you might have a Windows Mobile app but want to deploy it on Blackberry. Or maybe you have an iOS application but would like to change it for use on Android devices. Because of the new cross platform technologies you have the freedom to be selective or all-encompassing as you see fit. But a word of caution: it is important that you retain the end result source code as property of your company when you resort to cross platforming. You will have to make your app development team sign a 100% non-disclosure of project information including the source code. This means that they are legally barred from claiming ownership over the cross platform apps after the project ends. This is fair because you already paid them for their services so they have to turn over the entire rights to the project to you as the buyer.
There are actually many app development companies like Hyperlink InfoSystem that want to dive into the cross platform arena as well. Their past experience in app development may still be important in cross platforming too so do ask them about their current skills in app development. Some of these app developers could be in your own country while others could be from halfway around the world. This could make it a bit challenging to Hire cross platform developer because you have a wealth of choice. However, you can make it easier by searching through headhunter sites or posting ads on such sites. The advantage with hiring a developer from your own country is that it is easier to go meet with them in real time. At the same time though cross platform developers from other countries could give a more competitive pricing and project schedule. So you have to know what you are looking for before you search.
