From the founders of Timebird (earlier hunt: http://www.producthunt.com/posts...), Timekit looks like the root back-end that powered their first product. Interesting idea, considering the countless messages (via email, social, SMS) we experience and the associated friction of finding a schedule that works for multiple parties.

So this effectively gives everyone the ability to do what timebird does?

Pros:

none

Cons:

Difficult to cancel subscription
