One Purchase for iPhone and iPad ( Buy One Get 1 Free)

HI,

I have created an app for Iphone aspect ratio. But it just will not duplicate correctly for iPad due to screen aspect ratio. So I am thinking of creating 2 versions, one for iPhone and 1 for iPad. But can I create a purchase in AppsStore such that buy one version gets the other FREE?

Thanks so much for the assist!
