How do I get the app?

Collector for ArcGIS is available on the App Store for iPad and iPhone.


If you're looking for the original Collector app available on Android, iOS, and Windows, see Collector Classic.

Why can't I sign in?

There are a couple of common issues that may occur when trying to sign in. Verify that you typed your user name and password correctly. Make sure your account is part of an ArcGIS organization (ArcGIS Online, ArcGIS Enterprise, or Portal for ArcGIS 10.3.1 or 10.4.1). Collector doesn't support using ArcGIS Online public accounts. If you're using ArcGIS Enterprise, verify the URL to your portal instance, for example,

What is the licensing of the app?

Collector for ArcGIS is available to members of ArcGIS organizations. This includes those with a subscription to ArcGIS Online or an account on ArcGIS Enterprise. For more information, see ArcGIS account requirements for Collector and Licensing Terms of Use.

What is Collector Classic and how do I know which Collector app I should use?

Collector Classic is the original Collector app available on Android, iOS, and Windows. The app you are reading about here is an updated Collector app, currently available on iPad and iPhone devices and coming to Android and Windows in later releases.

You can have both Collector apps installed on the same device and transition to the new app as your organization is ready to do so. However, future development work is focused on the new app. You might want to continue using Collector Classic if it meets your project requirements and you are supporting mobile workers across the Android, iOS, and Windows platforms and want to keep your training device agnostic, as the new Collector brings a new user experience.


If you have both Collector and Collector Classic installed on the same device, and you open your map from a link (for example, through an email or Workforce for ArcGIS), there is no way to specify which Collector app is used.

Can my mobile workers open Collector from emails, websites, or apps?

Yes. By using Collector links in your app, website, or email, your users can open Collector. You can specify a particular portal that should be used or map that should open, and even the location the map should center on or a feature to search for. If you'd like to start capturing an asset or observation, specify the layer you'd like to add a feature to, any attributes you'd like to set, the value to assign to each attribute, and if there is an application to return to when the capture is completed. See Open your map from a link.


If you have both Collector and Collector Classic installed on the same device, and you open your map from a link (for example, through an email or Workforce for ArcGIS), there is no way to specify which Collector app is used.

How can I give feedback on the app?

The Collector for ArcGIS team wants to hear from you about the app. If you have feedback or inquiries, send an email to You can also provide feedback within the Collector for ArcGIS GeoNet community page.

Can I install a previous version of the app?

No, reverting to a previous version of the app is not supported. For details, see the Product Life Cycle for Collector for ArcGIS on iOS.

Does using Collector consume credits?

Collector does not consume credits; however, certain functions from ArcGIS Online that can be used in Collector do. For example, in hosted feature layers, adding features consumes Feature Storage credits, and adding photo attachments to features consumes File Storage credits. For details about credit consumption for these and other ArcGIS Online functions, see Credits in the ArcGIS Online View status topic.

Is my GPS receiver compatible with Collector?

Collector supports internal GPS receivers and external GPS receivers that output NMEA sentences. See Choose a receiver for a list of NMEA sentences that Collector can read and a list of GPS receivers that can be used with Collector on supported iOS devices.

What level of accuracy can I expect from a GPS receiver?

The best way to determine the accuracy level to expect from a particular external GPS receiver is to check the website of the receiver's vendor for GPS specs. If you are looking for the accuracy level of an integrated GPS receiver or if you would like to compare accuracy levels of various external GPS receivers, you might find the MTDC GPS Receiver Horizontal Accuracy Reports and Tested Accuracies published by the USDA Forest Service helpful. This organization has been testing GPS receivers of various grades to determine their horizontal accuracy in different canopy cover conditions, and in some cases, different GPS settings. While Esri does not endorse the Forest Service's results, they may be a useful guide to determine which receiver best suits your organization's needs. Esri does not officially recommend any specific receiver for use with Collector.

How do I use my Trimble R1, R2, or R10 Model 2 GPS receiver with Collector?

While most external GPS receivers are connected to your device and configured through their own apps and then work with Collector, the Trimble R1, R2, and R10-2 need to be configured directly within Collector. See Trimble R1, R2, and R10-2 configuration.

Is location tracking supported in Collector?

No, location tracking is not supported the same way it was in Collector Classic. In Collector Classic, tracking first came to ArcGIS as a special layer. This capability had a number of issues, the primary one being its lack of support for collecting tracks while in the background. The Collector Classic tracking capability was replaced by a new location tracking capability that allows sites to capture location data across their organization.

The new location tracking capability supports a variety of security and work management needs. The Tracker for ArcGIS mobile app, available on Android and iOS devices, is optimized for tracking locations in the background, minimizing the impact on device battery life. The mobile app records tracks independent of a data connection and provides mobile users control of when they are and aren't tracked.


The location tracking capability is available on ArcGIS Online and ArcGIS Enterprise 10.7 or later.

Collector supports viewing tracks collected through Tracker so that mobile users can see their tracks while working. Tracker stores the tracks locally on your device, so they are available even while offline. To view tracks in Collector, turn on My Tracks in Layers Layers. The tracks you see are configured through Tracker and honor the settings you make for viewing tracks.


Tracker for ArcGIS must be installed and the same user must be signed in to both Tracker and Collector to view tracks in Collector.

To learn more, see Tracker for ArcGIS.

Can I use basemaps copied (sideloaded) to the device?

Yes, you can copy a map tile package (.tpk or .tpkx) or vector tile package (.vtpk) directly to the device. Copied basemaps are available for use when working online or offline. To use the basemap on the device as the default basemap when downloading a map area, the map must reference it. If working offline, the copied basemap must overlap the extent of the map area and must have the same spatial reference as the default basemap. See Copy a basemap.
