First of all you have to know on what Operating System do you want to go.
Then you have to create some restfull api's that comunicate with your database.
You can use HTML5 included in your android or ios, or create your interface with the api's.
To be honest I had many concerns about jQuery , and I still have. But I use it. So sure http://jquerymobile.com/demos/1.2.1/ is a clean logic for the UI . But the UI is just the end point , the model , the data structure and how controller does it is the main. And UI isn’t the view.
