This app aims to provide a solution to the "movie store amnesia" problem.

Users maintain a list of movies they want to see. When they need to refer to it (presumably when they are about to rent a movie), they send a simple message to the service ("list") and receive a text with their list of movies.

The application also allows users to add items to the list by sending a text message ("add" moviename). There will also probably be a web interface through which users can remove movies from their list (move them to a "watched" or "liked"/"disliked" list).

The list could be potentially more interesting by also providing the users with recommendations (from Amazon.com or netflix?), based on movies that are (or were) on their list in the past.
