I saw this app a while ago, forgot to write it down of course. In its title it includes "things" or "stuff" or "the book of stuff", I actually can't really remember, it's about ordinary things you see every day, their story, how they changed through history maybe, how they were invented like the paperclip and so on... I exactly remember that the paperclip was mentioned either in the description or in someone's comment about the app, and I believe it has an old timer car on its icon. Does anyone know?
