For anyone who is organized-obsessed, Google Keep is the app for you. I like to think of them as "virtual" sticky notes. Create checklists, insert images or organize links. There are so many things you can do with notes. And--you can color-code them!

Beginner:

• Create a note and share it with someone else.
• Create checkboxes.

Intermediate:

• Insert feedback from Google Keep into Google Docs.
