30 Boxes is a minimalist calendaring IOS application[1] created by 83 Degrees.

[2] Originating as a web application in March 2006, 30 Boxes was founded by Webshots cofounder Narendra Rocherolle.

[2] Barry Collins of The Sunday Times appreciated the website's plain-language event adding feature, but did not appreciate that he was unable to see more than one month of events at a time.

Collins was also unhappy that the website was not capable of warning him when he had two events scheduled at the same time.

[4] They described 30 Boxes like “buying a new car with manual transmission and lots of extras—you don't just want to drive it, you want to fool around with it to see what it can do”.
