Introducing Field App: Felt's mobile app built for seamless data collection workflows on iOS and Android.
Field App brings Felt's modern mapping experience to your mobile device. Whether you're collecting data in the field, monitoring live operations, or reviewing dashboards between meetings, Field App connects you to your maps with real-time syncing across devices. Bringing an intuitive interface to field data collection workflows enables seamless collaboration between Felt's mobile and web platforms, which transforms how organizations bridge fieldwork and desktop workflows.
The app includes:
Full viewer experience: access to all your maps and dashboards on mobile
Built-in GIS tooling: measurements, spatial filters, table view, and search
Structured data collection: use Felt layers and surveys to standardize how your team collects field data on the ground
Geotagged photos: use location tracking to attach photos directly to features or location-based comments
Offline support (coming soon): work without connectivity and sync when reconnected
The mobile app is optimized for field work: you can view maps and collect data on mobile. To create and design maps, switch to Felt's web app on a tablet or desktop.
You need a Felt account to sign into the Field App. Create an account on desktop first, or ask your Felt admin to invite you to the account.
You'll immediately be prompted to log in. Our mobile app log in supports password and Google authentication. When using Google SSO/authentication, first enter your email address and tap "Next." Google SSO will be detected automatically.
If your team uses a non-Google SSO provider for member logins, contact [email protected] and we will assist you further.
Open a map
After signing in you'll be automatically directed to your Felt Workspace. You'll see the Felt home view showing you Recents, Felt maps you've recently viewed, by default. Tap on any of the maps to view the full map view.
Clicking on the menu (top-right) lets you navigate around the Workspace to switch into projects, maps, and manage Workspace settings.
The Field App supports deep linking for map links, which means when the Field App is installed, opening a map link on mobile will automatically open the map in the Field App. When your email address is invited to a map in the Share menu, you will receive an email with a link to view the map. Tapping on the link in the email will automatically open the map in the Field App.
Contribute
Your ability to comment or collect data depends on your permissions to the map being viewed. Viewers can open and comment on maps with the Field App. Editors can comment, draw annotations, edit features, and add new features. For more detailed information on permissions, see our FAQ.
Comment
Leaving a comment on the map is helpful for adding ad-hoc field observations and collaborating with teammates in real-time to resolve issues and coordinate plans. Data gathered with comments includes free text and photos, and you can tag teammates to notify them via email immediately.
Tap the plus button on the bottom-right and select Comment from the menu panel. (Viewers will see a comment button instead)
Pan around the map to position your comment. You can use location tracking to snap the crosshairs to your current location. Tap on the location icon on the bottom right of your screen.
Type in your comment in the bottom panel.
Viewers can tag teammates () and tag features (+ ...). Editors on enterprise plans can also add photos ().
Tap the pink submit arrow button to add comment to map
Tagging features
Comments automatically detect if you are near existing features, and you can tag specific features to associate the comment with that feature. When your comment is near multiple features, tap on the + Point at option from the comment panel to select which feature to tag in the comment.
When only one feature is nearby, the comment panel will mention the specific feature:
You can also tag features directly from the feature popup panel. Click on the ...menu in the popup panel to add a comment.
Managing comments
In the Field App you can manage comments on each map.
Click on the ... at the top-right of the map view to view the comment panel and all comments in list form. Double-tap on a comment from the panel to zoom directly to it.
From the comment panel you can:
Show/hide comments on the map
View resolved comments
Zoom to comment (double tap)
From this comment view panel, tapping on ... next to each comment allows you to:
Resolve comments
Copy a map link to specific comments
Copy comment ID (for API)
Delete comments
Manage individual comments by tapping on the ... menu next to the specific comment from the map view:
Use data collection workflows when you need to build and maintain a structured dataset, manage assets on the ground, collect records that will persist long-term, and to run reporting from field observations. Online edits on mobile are immediately reflected for other viewers looking at the map.
You must have editor permissions to create new features or edit data layers on the map.
Tap the plus button on the bottom-right.
Tap on the layer you want to add features to from the panel (ADD DATA section)
A crosshair will appear on the map where the point (or first point) will be placed. You can use location tracking to snap the crosshairs to your current location. Tap on the location icon on the bottom right of your screen.
Pan across the map and tap Add Point to place a vertex. For lines and polygons, the point will add a vertex to the shape and each tap will extend your shape from the last vertex
Continue panning to place additional points, tapping Add Point to place more vertices
Tap Done (or double-tap Add Point ) to exit edit mode
While drawing you can undo / redo your edits by tapping on the arrows (bottom-left)
Supported data types
Points
Lines
Polygons
Edit existing features
To edit existing features, tap on the feature and then tap on the pencil icon from the popup panel. You'll first be shown the attribute table to edit the feature's attributes, but tapping Edit geometry allows you to adjust the shape of the feature.
Tap any existing vertex to select and edit it, or move the entire shape by dragging it around the map. For lines and polygons, pink-filled circles, called "hint vertices" will appear between vertices as you zoom in around a shape. Tapping them will add new points to the layer between the existing vertices.
Hint vertices (pink-filled circles) are a quick and easy way to add complexity and detailed edges to the geometry of existing features.
Deleting features

Location tracking
The Field App can connect to your device's GPS setting to contribute to the map based on your precise location, which updates in real time. You can add points (and soon trace paths) based on your location. You can access this setting by tapping the location icon on the bottom-right of the screen. The first time you enable this you will see your device ask for permission to use your location.
When location tracking is enabled the icon will be a solid blue and your location will appear on the screen as a blue dot.
While collecting data you can use location tracking to snap the vertex to your current location. While drawing on the map, tap the location icon to snap the crosshairs to your location. You will see location accuracy indicator in blue at the top of your screen. Tapping on the accuracy indicator will show you more details on GPS accuracy.
Frequently asked questions
What plans have access to the Field App?
The app is accessible to all plans. Everyone with a Felt account can download and use the Field App to view maps.
Enterprise customers have access to premium features in the app, including:
Mobile data collection
Adding photos
Data editing
Offline maps
Contributor license
What's the difference between viewing a map on my mobile browser versus the Field App?
Both experiences are optimized for mobile, but the Field App offers the best mobile experience of Felt maps. We generally recommend downloading the app for Felt maps on mobile.
For Enterprise customers, Felt offers enhanced functionality for desktop and mobile:
Photo capture for comments
Surveys and data collection
Offline support (Field App only)
How does sharing work on mobile?
Anyone viewing maps in the Field App needs to have a Felt account, so they should be invited to the map or to your Felt workspace.
Public sharing (access for anonymous viewers via map link) allows viewers to open the map on desktop or mobile browsers.
Can I create new maps in the Field App?
No, the mobile app is optimized for field work and data collection. To create and design maps, you'll need to use Felt's web app on a tablet or desktop.
What are the key differences between the desktop and mobile experience for Felt admin and editors?
There are a few key differences to outline:
The desktop interface has pink Edit /Done buttons at the top of the screen to toggle into edit mode, while the mobile experience does not have this toggle.
A toolbar is visible at the top of the screen while editing on desktop, but the mobile toolbar sits within the pink plus button at the bottom right of the screen for editors.
The legend sits on the left-hand side of the screen, while the legend on mobile sits in the bottom panel of the view.
Currently custom extensions only run on desktop maps, not yet on the mobile experience.
The desktop editing experience requires internet connectivity, while mobile supports offline viewing and editing mode.
Legend interactions, and workspace navigation experiences are very similar across all platforms.
How can I use the legend on mobile?
The legend is fully interactive on mobile, and so are layer components. For more information see Bottom panel
Can I work offline in the Field App?
Offline support is coming soon! When available, you'll be able to download maps before heading into the field, continue working without connectivity, and sync automatically when you reconnect.
When should I use comments vs data collection?
Use data collection when you need the information to persist as a feature, collect data in a consistent format across your team, manage assets, and creating datasets that need to be analyzed in spatial reports. Data collection creates layers in Felt.
Use comments when you need to communicate quickly, flag something temporarily, or share observations that don't need to be part of your permanent dataset
How do permissions work with the Field app?
Viewers can:
Navigate the Workspace projects, folders, and maps on mobile
View maps
Search on maps
Change basemap
Interact with the legend
Utilize table view
Add, edit, and delete comments
Add comments to features
Use measure and spatial filter extensions (enterprise only)
Starting in January 2026, Felt will offer a new "Contributor" license to Enterprise customers. Contributors will be able to edit and collect data in the field, but they won't have full Felt Editor access to be able to create maps or manage projects. To learn more, contact sales.
How do I draw a circle with the Field App?
Felt supports drawing circles for annotations, measure, and spatial filter extensions. Tap the map to set a center point, then drag your finger across the screen to set the radius and adjust as needed.
Are custom extensions available on mobile?
Felt's spatial filter and measure extensions are available, and you can search the map in the top-right.
The search extension and running custom extensions on mobile is coming soon.
Does Felt support deep linking?
Yes, when the Field App is installed, tapping on a map link from on mobile (from an email, slack message, etc) will automatically open the map in Field App.
