Have you seen the show Higashi no Eden? Friends of the protagonist created an app that would let them identify everything, people included. Everyone had the ability to identify new things and add to the database. It was a pretty neat tool, but utterly futuristic back in 2009 when the show aired. That was about when smartphones became common.

And it looked a lot like that screenshot from the site.

The concept was kinda dwarfed by the real point of the show, which was a mobile phone with a billion or so and an operator doing tasks for you by using that money. Like shooting rockets or shipping all shut-ins off to Africa or something like that. Good fun.
