How I Use It
I used this app as an alternative to a power point. My students are beginners with microsoft office and are excited to learn power point. We used Prezi instead and it was much more open ended and required more vision and creativity from the student as to what the end product was ultimately going to look like.
I would use it again although, it was discouraging that students had to set up an account, publish their work publicly (if not subscribing $), and use a desktop rather than an ipad to be able to use all of the features of the app. Also, you cannot simply go to the website from the ipad because the device recognized the app and kicks you out of the website to the app automatically, which has the limited features.
