Impact on user experience

Large app sizes negatively impact the user experience in several ways:

  • Lower installation rates: Users are less likely to install large applications because they take longer to download, which can lead to frustration.
  • Increased uninstallation rates: Users may uninstall large apps to free up storage space.
  • Lower update rates: Users may avoid updating large apps due to the time and bandwidth required.

Threshold guidelines

It is recommended to keep the installed app size below 100 MB. If the app exceeds the threshold, it is highlighted in red.
