Reading long articles on the web can be a pain, but Pocket makes it easy to save and read content in its slick minimalist UI. This app has been great since it was redesigned (it used to be ReadItLater), and the most recent update makes things even better with the ability to share and tag content as you're saving it.
Now when you save a page to Pocket on Android, there will be a Quick Save popup at the bottom with a direct link to the app, a tag button, and a share button. If you want to add tags or share the link, that stuff comes up in a floating window rather than the full app just taking over the screen.
The update also included some improvements to video playback, but the Quick Save Actions are the main selling point. Although, Pocket isn't really selling anything – the app is free.
