The Christmas Card List is an iPhone app developed by David Breed that helps users keep track of their Christmas cards. This app is perfect for those who are tired of forgetting who they sent a card to last year or who sent them one. With The Christmas Card List, users can easily track the cards they have sent and received from previous years.

One of the best features of this app is that it eliminates the need to write addresses on envelopes, which can be a pain and time-consuming. Users can select their addresses, choose the label they want, and print using AirPrint or email it to print later. The app also allows users to sign in using their Google or Facebook account or create an account to sync their information between all their devices. The Christmas Card List is simple and easy to use, making it a must-have app for the holiday season.
