Save a map to your device ahead of time, work fully offline while you're out of cell range, and the app syncs your changes automatically the next time you're back online. Offline support is available in the Field App on both iOS and Android. Make sure you're on the latest version of the app from the [App Store](https://apps.apple.com/us/app/felt-maps-field-surveys-gis/id6754033379) or [Google Play store](https://play.google.com/store/apps/details?id=com.felt.mobile). {% hint style="info" %} Working with offline areas requires a paid editing seat: an **Editor or Contributor** license on legacy plans, or a **Full Access** seat on current plans. {% endhint %} ## Download an offline area 1. Open the map you want to take into the field. 2. Open the **Felt menu**, choose **Offline areas**, then **Download offline area**. 3. Drag the rectangle on the map to choose the area you want to download, then start the download. 4. You'll see the download progress, and the status changes to **Downloaded** when it's ready. The app downloads the map's data layers and the standard Felt basemaps for the area you selected, so you can view and switch basemaps offline. You can download more than one offline area. The app home is also browsable offline, so your downloaded maps are available even without a connection. ## What you can do offline Once a map is saved, you can keep working on it without a connection. What you can do follows the same [seat and map permissions](/field-app/getting-started.md#contribute) as when you're online: anyone can view, members with a Full Access seat can comment, and members with Contribute or Edit permission can also collect and edit data. Offline you can: * Add new features to layers * Edit feature attributes * Attach photos to features * Add annotations * Add comments * View, pan, and zoom the map, including zooming in beyond the saved detail level * Tap features to view and query their attributes * Browse, sort, and search the data table ## How syncing works Any changes you make offline are saved on your device and queued to upload. Your edits are durable: they survive closing or force-quitting the app, so nothing is lost if you put your phone away before reconnecting. When your device comes back online, the app syncs automatically: * Your queued changes upload to the map for everyone to see. * The map pulls in changes other people made while you were offline. A syncing indicator shows while your changes are still uploading. Wait until syncing finishes before closing the map to make sure everything, including photos, has been sent. ## Things to keep in mind * **An offline map is a point-in-time snapshot.** Layers or features added to the map after you saved it won't appear offline until you save the map again. * **Custom basemaps aren't available offline.** The standard Felt basemaps are included so you can still switch between them in the field. * **Some functionality is disabled while offline.** Certain styling and editing tasks aren't available without a connection, such as styling layers and uploading data. ## Troubleshooting * **Changes haven't synced.** Reconnect to the internet and open the map. Watch the syncing indicator and keep the app open until it finishes. If you run into anything else, reach out to . --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://help.felt.com/field-app/offline-support.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
