# Offline Estimator Playground

[Offline maps](https://docs.mapbox.com/help/dive-deeper/mobile-offline/) are a feature of the Mapbox Maps SDKs for iOS and Android that allow for full map rendering without an internet connection. Offline maps are defined using **offline regions**, which specify the area and zoom levels of map data to be stored on the device for offline use.

Storing map data offline consumes both network traffic and device storage, so it's important to understand how offline regions work and how much data is required to cover a given area.

This playground helps you understand the relationship between offline regions and the required **tile packs** needed to cover the specified area and zoom levels. By providing a GeoJSON geometry and selecting a zoom range, you can see how many tile packs are necessary to store the map data for that offline region.
