> Basicaly a gamified editor that makes it easy and fun to fill in opening hours and [other] important metadata while on the go. Frankly its almost addictive. :)

When I read your description, I thought that maybe it was an app that prompted you to take a picture of the operating hours sign at a store when you visit, then sends the picture to a queue for someone to do the actual entry. The actual app is entirely different, but my idea might allow even more casual users, like me, to contribute. I don't have time to play an AR game like that, but I could easily snap a few pictures or answer some simple questions when I'm on the go.
