Evernote is a dream come true for information hoarders like myself. In a snap, I can bring text, screenshots, photos, and files into Evernote, annotate them, and combine them into notes.
To fit different style of working, Evernote provides abundant tool options to choose from. On my phone, I use their iOS app and sharing extension. On my tablet, I use their Android app. On my Mac, I mostly use their native app and sometime their web UI. I also use the Evernote Helper that shows up in the Mac menu bar and the Evernote Web Clipper in the web browser. That covers all of my workflows nicely.
