Google Keep is the app that I probably use more than any other on my Pixel 5. It’s an app that does everything I need to save notes, clip bookmarks, and set reminders for myself. It also has a lot of little “hidden” features that I use from time-to-time. For example, you can use to add voice notes to pictures. 

To add a voice comment to a picture in Google Keep you simply open the app and tap the camera icon in the “take a note” field. Then after taking your picture (or importing from your camera roll) tap the “+” icon in the lower-left corner to add a note. You can choose to type a note or your can tap the microphone icon to record a note. Then just start speaking. The audio file will automatically be attached to the note containing your image.

Applications for Education
Sometimes a voice note more accurately conveys what a student wants to remember about than a text note does.  Adding voice notes to pictures in Google Keep could provide students with a relatively easy way to make notes for themselves about a diagram or math problem that you’ve shared with them.
