# Device Memory API

## Overview

Device Memory API returns how much RAM the device has in gigabytes, rounded down to the nearest power of two.

This allows us to make runtime decisions about what resources to serve based on the returned device memory value, for example, serve a 'lite' version of the app to the users on low-memory devices.
