App Idea: About people you know

I have a terrible memory, and as I get older, I know more and more people and I get to see them less and less. When I do see them and get to chat with them briefly, I wish I was better and remembering what they tell me. Maybe they started a new job, or they've been enjoying a new sport, etc. But alas, I forget.

I'd like an app that would tie into Google Contacts and would allow me to easily store notes about people so that when someone comes to mind I can remind myself of the things that I would otherwise forget. It would need to work via the cloud and I'd want to be able to access it via all of my devices: Phone, tablet, PC, etc.

Perhaps it is simple as having easy access to the "Notes" field and dressed up a little in terms of a slick UI.

I suppose the standard "Contacts" app could be used for this, so that's a place to start to see whether the UI is good enough.
