It's a great app I picked up a couple years ago.

Anytime you're online, no matter what you're doing, if you see a story or picture, or comment, or video, or anything else that interests you and you'd like to look at it later or keep it for any reason, you just click the share icon that's on pretty much everything, and it keeps it all in one place organized by folders you label yourself.

Mine are like "helpful", "movies", "things I want to buy", "tech stories", etc. Just whatever articles or videos or links you're interested in or want to keep for whatever reason.

Another thing I like about it is that it strips out ads and popups so you can just see what you want to read or watch.

The basic version is free and is really all you'll probably need.
