# SDK Size

The Chartboost Monetization SDK adds the following to your app. Each number is the difference between a minimal app built with and without the SDK, so it reflects the SDK's marginal cost on top of your app rather than the size of the downloaded package.

<p><em>Measured for version 9.13.0 on 2026-07-17. Download size is bundletool's `get-size total` figure for the release app bundle -- the same computation Google Play uses to compute a device's download size -- comparing a build with vs without the SDK; the value reported is the max of the min/max range bundletool returns across the device configurations it matched. Install size is a build-time proxy: the uncompressed size of a release APK's zip entries, built with R8 and resource shrinking, since no public tool exposes Play's actual on-device install size. The SDK ships no native libraries, so both figures are the same on every CPU architecture. Your app may see a slightly different figure depending on the SDK features and dependencies it already includes.</em></p>



**Download size** is the compressed size added to what users download from the Play Store. **Install size** is the uncompressed size on the device after installation.
