Codify

Though it's named a bit unfortunately, this Codify app is a rather useful application to have in your arsenal. It aims to be the definitive way to share contact information. It's not aiming to replace your Contacts but, rather, be the point of information exchange to keep them all up to date. I signed up the other night and have been enjoying the notion that if I updated my info within the app it would update with everyone else who has the application - no more alerts that a phone number has changed or an email was retired. I'm sure there are other apps that also do this but this one is slick and easy to use. Definitely recommending.
