html5 offline application on multiple platform

Question

I want to develop a offline web app which will work on multiple platform(PC,Android). This is a basically a product display web app so that each product will have image,video,details of product etc. For development of this web app HTML5 is the choice. I will copy web app files to each device so that I could run it offline. But here I need a back-end so that I could delete outdated product and add new products(which will have details,image,video). Is there anyway so that I could add/delete product from one device and copy these files to all other devices.

I have come across HTML Appcache, using this i can build normal php site and using manifest i can store it in browser appcache for offline viewing. But this requires internet connection in each device and access the web app through browser.

I would like to know if there is any other way I could do this without keeping files in web server.

I think something like PhoneGap is probably what you're looking for (Apache Cordova)

Also be aware that app store policies may end up dooming your app if it doesn't look and feel native. Expect Apple to be very strict about this.
