'Idee' mobile app
Idee is an app (currently Android only) which is in development. The goal of the app is to allow people to control how other people see their own identity information, and to ensure that the details that they have in their contacts app is correct and up to date. When a user signs up, they are prompted to create their own 'identities' (e.g. personal, work, family).
Then, whenever they make or receive a call, they receive a notification where they are asked if they would like to share their contact details with the person that they spoke to, and if so which profile. It has the potential to change the way that people connect, and to make our address books more accurate (an issue which still isn't solved by anyone despite advances in social networks and a decade of trying!).
This is currently being built as a small experiment to test the concept during early 2015. The Axure prototype can be viewed here.
