From the app icon size to the screenshots, images play an important role in marketing an app. Using the correct dimensions for app screenshots seems as though it would be a straightforward task, but there can be some confusion over the correct app store icon size and formats.
The App Store and Play Store have different technical requirements that must be met. Having the right size screenshots ensures that none of your images come out distorted, adding to your app’s quality. As well, ensuring you follow these requirements can help your app get accepted faster.
