I have written an iphone prototype of an app but would like to convert this to an html 5 version that will work on Android and Iphone.
The web app will have a login page that will check against a database, it will pull data from a database and show a multi-level menu to the user (like iphone list), and the user can select items like a shoppint cart. When they checkout they will be able to store credit card details and pay via a payment gateway. the Order will be sent to the database via a webservice. All integration with the website is using SOAP currently.
Also need a map page that will put pins down for retrieved locations found on the database. This will be based on the users location.
The items retrieved from the database will also have discounts attached such as 2 for the price of 1, 10% off on tuesdays and the app will need to manage this when an item is selected (i.e if they choose a product that is 2 for 1 then the shopping basket would have two items (one that is free).
Finally, the retrieved items will also have optional add-ons which can be selected when the user chooses an item.
