Installed App Size

The App Size metric is the size of the app after it is installed on the mobile device.

Impact on user experience

Apps with large install size require more space on a user’s device to complete the installation. Users avoid installing apps that are too large especially on cellular networks. Bigger apps have low conversion rates, slower downloads, higher uninstalls, and lower update rates.

Threshold guidelines

It is recommended to keep the installed app size below 100 MB. As per a Statista 2022 survey, top Play Store apps are within 55-75 MB size.

Recommendations

The following are recommendations to improve the installed app size:

• Remove unused resources: Use the lint tool to identify and remove resources in your res/ folder that your code doesn’t reference.
• Use specific screen densities: You don’t need to export your rasterized assets to each density, just export them to specific densities.
• Use compressed image formats and vector graphics: Optimize for resources using compressed PNG and JPEG files and vector graphics wherever possible. Vector graphics take up less space compared to rasterized images.
• Use Proguard: This tool shrinks, optimizes, and obfuscates Java code, reducing the overall size of your app.
