Twilio Development` is a Ruby application built with Sinatra and Datamapper on Heroku that uses the Twilio API to send SMS alerts for new content, such as the premiere of Arrested Development Season 4 on Netflix. To detect when the season goes live, it uses a scraper written in Nokogiri. The application allows users to subscribe to receive notifications via SMS by texting `ANN` to a specific number, which was created by developer Jonathan Gottfried, also known as "BananaAlerts".
