You should start by learning something about mobile development and something about web development. Given the fact that you seem determined to post as few words as possible here, it seems like you want some magic solution that will involve no work, but there is no such solution. It should be obvious that you need to understand at least the basics of the technologies that you want to use but you've provided no indication that that is currently the case. Fix that first. Once you have some actual information to share with us, e.g. what you're actually trying to achieve with this app and how the functionality should be split, then we will have something worth discussing.
