This may be old news to some of you...

Google Keep for the desktop is handy for putting lists, notes and images in. Then you can sync it with the Google Keep app on your cellphone. You can pin important stuff to the top and set reminders that will alert you to whatever is due. On your cellphone you can make a note and email it, send it to Twitter, or add it to Google Docs.

It works with other browsers, but Chrome works the best on the desktop. I'm guessing it works the best on an Android cellphone, but there is an app for iPhone too, that I use.
