The Twestival App was developed pro-bono by the Future Workshops team, in partnership with The Noble Union design agency. The App was developed to support the fundraising goals of the official Twestival charity, Concern.

The App enables Twestival participants to "Tweet" - keep track of local and global Twitter streams, "Meet" - mutually Follow other Twitter users by bumping iPhones together and "Give" - keep track of each events fundraising totals. The App is fun and intuitive, encouraging exploration of the global event.
