I need an app for Android and IOS (with sources and binaries) with the following functionality - Initial setup (2 parameters: Username and email). If the user doesn't have a registered user show a link to the registration page) After entering the username and email the app sends a message to validate both against a built in URL in the app. The answer will 0=ok , 1=error. If everithing is ok the app goes to the main functionality - An initial screen giving the option to read a QR code. - After reading the QR code the app gets an unique code (i.e key), that is signed with a md5. - The app validates the md5 rebuilding a new md5 on key+secret phrase. - Secret phrase is built in the app - If all is ok (QR code md5 and rebuilt md5 are equal) it shows the next screen - In this screen we have 3 options - One button that says I like it : when is touched the app sent a message to a server (the url is built in the app) with Key, Username, and the operation code = 1. The answer should be 0=ok, 1=err and a variable named SL with an integer number inside. The app should show the number in a space of the screen reserverd for this. - Other button that says I want it : same idea but the operation code = 2 - Other button that says I like/want it : same idea but the operation code = 3 Finally you have an option to read again a QR code and start again. All outgoing and incomming messages are signed with md5 and the secret phrase in order to avoid fake messages. Sources and binaries are required.
