Reel App provides a nice service for sharing your PPT, PDF, and image files with the world. A lot of other services do the same. What Reel App adds to it is the option to get feedback from your audience on each slide or image in your shared file.

Here’s how Reel App works. Upload your file to have Reel App provide  you with an unique url for sharing of your file. Send your audience to that url to view your presentation. Your audience can view your presentation on their laptops, mobile phones, or tablets. As you go through each slide, your audience can give it a “thumbs up” or a “thumbs down” to provide you with instant feedback. After everyone has gone through the presentation you will get summary page containing the overall feedback.

Applications for Education
Reel App could be a good way for students to get feedback on presentations that they give in your classroom or that they give online. Teachers could use Reel App to perform quick checks of understanding on each slide in a deck. Have students use the “thumbs up” if they think they understand the topic of the slide and have them use the “thumbs down” if they aren’t sure that they understand the topic.

Reel App is produced by the same folks who created Bounce, a collaborative screen capture tool that I reviewed last year.
