A Youtuber I watch mentioned this site/app in a video the other day, basically it's a social media site for sharing your collections of stuff [movies, games, anime figures, ect.]. Works really easy and doesn't get bogged down in a bunch of useless frills; you just create a "shelf" on your profile, use the app to take a picture of the thing you want to put on the shelf, and then input some basic information about it. My main use for it is to keep track of the Saturn and Xbox games I already own when I'm at a game store or con, but it's also nice to flip through all the junk I own without actually having to dig it out. It's also cool to see what crazy or really rare stuff other people have.
Here's my profile, so you can check out what it's like:
