Tellagami is a great mobile app. You can use a photo (or a stock) background. Add voice or type in dialogue. You can send it by text, twitter, email, and embed one in an online class.
You can post a slide, a saying, or learning artifact to reinforce learning. Or you can have students post a picture of something and narrate it for a class assignment. Click here to view how to use tellagami for learning (30 secs): https://tellagami.com/gami/2JJ5NN/
