Simple can be useful.
With Croak.it you can record a thirty second message, and no more.
Your “croak” is saved and you get a unique url address that you can share. There is no need to register. Croak.it is also available as a mobile app (iOS & Android).
Could this be a way of reminding children of a homework challenge? How about another challenge: can you explain the science idea, or project, in 30 seconds?
