John Gruber wants you to collect your thoughts.

That’s the goal of his new note capturing app called Vesper that he launched today with fellow Mule Radio podcaster Dave Wiskus as well as developer Brent Simmons. Gruber and friends launched their development company today called Q Branch and Vesper for iPhone is their first app… and boy is it flat!

You can drive Vesper for iPhone starting today for $4.99 on the App Store.

Update: Rene Ritchie of iMore has an interview with the team on this week’s Debug podcast.
