UpTo today announced it has launched a new social application focused on the "future tense," allowing users to see what their friends are up to ahead of time and share what they will be up to directly from their existing calendar. UpTo is one of only 40 start-ups chosen to launch at this week's prestigious LAUNCH Festival in San Francisco.

Unlike Facebook and Foursquare, which allow people to share the recent past and present, UpTo delivers both social and utility value by focusing on the future. UpTo deeply integrates with the user's existing calendar to allow them to share and comment on meetings, appointments and events with a network of friends. With UpTo, users control exactly which events get shared and with whom.
