The app I introduced in class was Magisto. This app allows the user to transform their personal videos and photos by adding filters, audio, and effects. The user has a limited set of options to select from (in terms of filters, audio, and effects), and then they wait while Magisto generates the video.
What I didn’t like about the app was that it does not let you know that you have to pay to share your video until after you’ve invested time creating it. I felt like I completely wasted my time and was not interested in purchasing the “upgrade”.
