iOS and Android App Preview Videos
Preview videos are the first contact between users and your app. They are short demo videos meant to demonstrate the features, functionality and user experience for your apps and if done correctly they are meant to increase downloads.
With an absence of demos and free trials on the App Store , it has been very difficult to explain the true value of your application to prospective customers. If your app was difficult to explain in text or to show off with some screenshots, you were out of luck
Usually there are two directions for app previews: showcase app features in order to win interest through diversity OR transmit the key purpose of the app in order to create a new market or new interest for the app
