So, I wasn't able to use QuickTime player for my app review due to my poor timing skills, but I managed to create one with iMovie. I took screenshots of the different menu options the app had to offer. I recorded the video of David's tips to show what app users should aim to practice, and also myself playing with the app. I do hope this result works out. Hopefully I can learn how to better manage my time so I can try using QuickTime.
