iPhone is highly used handheld device in the market. Its selling touches new high in the market of handheld devices. Due to its broad customer base you can get larger numbers of iPhone app users and this leads to unprecedented growth of iPhone app development and this is evident in Apple app store with high surge of applications for iPhone.

You too can get good fortune from your app development if you are a developer. If you are not a developer and want to earn substantial amount from Apple store just registering as a developer and giving your development work to a reputed outsourcing company which would develop an iPhone application behalf of you and even help you in the marketing of it.

Your iPhone application development should be with eye candy design so people will be attracted at your app at first sight and would like to use it again and again. Another thing is usability. If your app is not good at navigation then none would like to re-use it so make your apps’ navigation user-friendly and tempted your users to use it frequently as possible since the navigation in mobile devices are not like desktop experience. It is touch and tap phenomena performed by fingers and thumb, this again be precautious for the size of your apps’ icons.
Same is true for iPhone application; it should be function in a limited screen. Moreover, there is accelerometer which leads to changes in application layout with each flip. So your application should be such a way that it functions in both modes, portrait and landscape. Apart from these considerations you should be careful about GPS, etc. because web apps cannot have access of such functionality only native apps have access of such APIs. Screen size of iPhone is smaller in compare to other computing devices like iPad and laptop therefore you should be careful about the content. Images should be compact enough so they fit in the screen and text should be minimal so your users have to read as little as possible and able to get clear picture.
