# 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.

SDK size figures for this platform are not available yet.

**Download size** is the estimated compressed size added to the App Store download. **Install size** is the uncompressed increase to the installed `.app` bundle. Figures are from a Swift app; an Objective-C app is within a few kilobytes.
