An icon is the cover of your product, which is displayed not only in the store, but also on the home screen of the smartphone of users who have already installed the application. Therefore, it is important that it not only reflects your brand, but also appeals to the audience and stands out from the competition.
In the search results of the App Store, in addition to the icon, title and subtitle, the user sees screenshots or an event. In Google Play, things are different - in response to a request, the store displays only the names and icons of applications. Therefore, when promoting an Android application, you should pay special attention to this graphic element.
