The document discusses a time tracking app called Chronometrium that automatically tracks a user's time. It has a freemium business model where basic analysis is free, while advanced reports and notifications require a paid subscription. The app aims to help users spend more time on important tasks by analyzing their time usage across different categories using data from their Facebook, Foursquare, and other social media profiles. The market size for similar apps like Facebook and Foursquare is mentioned for context. The minimum viable product would involve editing existing activity categories tracked by the app.
