I require a simple app that would interact with a wesbite/database being built. The User makes (or recieives) requests on the GUI(I have designed the steps). This would then be submitted to the website/database to look for a match for the request. The webiste would then trigger a message to the app with a reference code. When a match is found for the request the app would be sent another message. Therefore an automated multiple way response by between the app and website is required. GPS coordinates functionality would be required.
