convert/compile html5 into android/iphone/windows apps

I have a complete working version of html5 app and I want to convert into native mobile application in iOS/android/windows app with added features. the present app is fully working with interactivity, multimedia and assessment functions. Looking for additional features like touch/pinch/drag etc. I have already built app using phonegap but the results were not appealing. so I want someone to look into the interactivity and make a complete application. It is urgent and want help till google play or itunes sharing.
