    I need an app to scan the ingredients on a food label and check them against a list of allergens or unwanted items. This app must be able to take a photo of the food label and then convert it to text for cross referencing the list. The app will need to interface with a database of ingredients with descriptions of the item. This database would be located on the phone, but would need the ability to update remotely from a web location. I also need the users to create a user ID/Password to log into the app. I would also need the developer to populate the initial database and provide an interface to load in new items from my side.

    Personalised products shopping applicationObjective: to create a HTML 5 mobile app to personalise and buy books, toys and gifts.Customers will browse through a mobile / tablet product catalogue and select products to personalise. Products may have several lines of personalisation, ie. several personalised fields. The app should allow for preview of the product. URLs with a &quot;Blank&quot; pdfs will generated once the app build has begun. Customers should be presented with cross sell products once they have added the item to the basket. In addition, the app should save the personalised data as a profile so that customers can use the same name and details on multiple products. Multiple profiles should be allowed.  Customers will need to be able to upload a photo for the preview. Ideally they will be given the option to crop the photo during the upload process - or the app will detect the frame of the face and set the crop automatically. Ideally customers will be able to have a smooth coupon redemption journey. For example, after clicking on the BOGOF banner they will select and personalise each product, moving smoothly from one product to the next. The product data should then be transferred to a Magento (Enterprise 1.9) mobile shopping cart via API to complete the transaction. I am happy to consider other alternatives for processing checkout and payment as long as the customer experience is not compromised. As long as the functional objectives are met the site could be on a platform such as Wordpress with the appropriate plug ins.I would ideally like to see prototype examples of each component prior to engagement as proof of concept. The attached document shows draft wireframes.Final delivery required including testing and revisions within two weeks.
