Narrative Notes with Movenote

What is it?

Movenote is basically a memo maker that you download to your mobile, with an interesting format: video box + photo box on the same page. In other words, the note is orally recorded as video to complement (or be complemented by) a still image.

How would I use it?

Learners can select images as stimuli for speaking tasks and record their responses. The Share feature easily links to social media, and there is even a mailbox for receiving Movenotes from others. It seems a good way for teachers to detail assignments for learners as well. Provided instructions aren't too long, it may prove more effective for learners to hear and replay them on the phone rather than search for the file to read and reread.
I am especially intrigued by its potential for pre- and post-task reflection. Say the students had a reading task, sending a still image for them to video-comment on could generate interest in the topic, and provide good material for in-class discussion. I am curious to hear other ways in which this tool might be used. Ideas?
