Extremely clean design, great usability and performance. Clearly this is the work of an incredibly talented technology team.

This is a nice app for attendees of TED 2012. I like being able to check in to the different locales at TED 2012.I also like having the Conference schedule interactively explorable in the app.It has a few "version 1.0" rough edges that I expect will smooth out as it's tuned and tweaked.Overall, very good.

Use it all the time, great app to have. Congrats!
