Five Powerful Google Keep Features You're Not Using. I recently introduced you to the great, free Google App, Keep, which is a great note and list making app. Organized people have been making lists for a long time. In the old days, we wrote them down. Then, after we adopted computers and personal digital assistants, we started making lists on those devices. Nowadays, we use our smartphones; and, Google's Keep is simple, easy to use, and propagates everything across all of our devices. Here are some functions you aren't using that expand Keep's utility. My favorite? Take a photo of anything, and save the image text. You now have a digital copy of the text for use elsewhere. "OK Google". "Take A Note". "Remind me to use Google Keep more".
