App Size Analyzer

Analyze and optimize mobile app size

The App Size Analyzer quantifies a mobile application package's storage footprint (e.g., Android APK/AAB or iOS IPA). It meticulously breaks down the total app size into core components: native code, managed code, assets (images, audio, video), third-party libraries, and resources. This granular analysis precisely reveals which elements contribute most significantly to the overall application size. Mobile developers and release engineers use this tool to identify opportunities for reducing the app's download and installed size. By pinpointing oversized assets, redundant code, or large third-party libraries, developers can implement targeted optimizations. This leads to faster downloads, lower data consumption, and a smaller device storage footprint, enhancing user experience and acquisition. The analysis output is a detailed report, often visualized as a hierarchical breakdown. To interpret, users focus on components with the largest size contributions. For example, if image assets show a high percentage, compression or format changes are indicated. A large "libraries" section suggests reviewing dependencies for unused code or smaller alternatives. The goal is to prioritize and execute optimization efforts based on each component's impact.

How it works

The result is derived through the following steps:

  1. otherSize = inputs.apkSize - inputs.codeSize - inputs.assetsSize - inputs.librariesSize
  2. codePercent = (inputs.codeSize / inputs.apkSize) * 100
  3. assetsPercent = (inputs.assetsSize / inputs.apkSize) * 100
  4. libPercent = (inputs.librariesSize / inputs.apkSize) * 100
  5. rating = inputs.apkSize < 20 ? 'Excellent' : inputs.apkSize < 50 ? 'Good' : inputs.apkSize < 100 ? 'Average' : 'Large'
  6. recommendations = []
