The iPhone and Android Application in our first release will be for user registration (or login) and then receiving push messages (or the Android equivalent), presenting them to the user and, if applicable, getting responses. The 1st version will be in English and a specified color scheme, but the app should be build on a platform that allows easy conversion to other languages and skins. Most of the intelligence of the app will be performed at the server, but the app should record transactions when off-line. Further the app will record the features and actions of the user and feed those events up to a server for analysis and subsequent use to optimize the application. We have complete specifications for the app which will be provided upon completion of the NDA. Experience with CalDAV will also be helpful for this app.
