Sensor Tower’s platform offers multiple data-slicing options based on time, country, device, and more, but it can also dig even deeper to uncover surprising insights. Custom Fields allow your team to filter millions of data points down to specific cohorts of apps in ways specific to your needs.

Like Global Fields, custom fields are comprised of one or more tags such as True and False.

Apps can be tagged using several methods, including by CSV import and through Sensor Tower's Advanced Search. This article covers how to tag apps from within views available in App Intelligence, Store Intelligence and Usage Intelligence. Batch tagging is not available in Unified views. 

Imagine you are considering introducing a Season Pass as a monetization strategy to your Arcade game. You might wish to isolate the most successful Arcade games that have already done so and tag them as such so that you can easily view, track and analyze this niche throughout multiple Sensor Tower products.

Choose a cohort to tag

1. From any area of the platform that you see the Analyze option, determine which apps you would like to put into a cohort.

   Batch-tagging is not available in Unified views. You can, however, easily tag all sub-apps of your selected apps (including both App Store and Google Play Store versions) with this process.

2. Check the Analyze checkbox beside each app you wish to tag.

Add a custom tag

1. Above the column headers, select the Add Tags dropdown menu.
   
   

   On the left you will see a list of custom fields that are available to you. These will be those you have already created and those made by others who have made them visible to your organization.

2. If you wish to tag this cohort with a pre-existing custom tag, simply select the desired custom field from the list.
   

   If you have many custom fields, the Search Field bar can help locate the one you want.

3. Choose the selected custom field's tag you wish to use from the right pane.
4. Click Apply Tag.

Create a new custom field

1. If you wish to create a new custom field, you can use the New Field functionality in the right half of the Add Tags dropdown. If this is not visible, click New Field at the bottom of the list of fields on the left.
   
2. Enter the Name of your new custom field. 
   

   Some users like to use their initials or similar to keep track of who created a given field and make their own fields easier to find.

3. Enter your desired tags separated by commas. These will be the tag options available to you when you select your custom field dropdown. You must enter at least one tag.
4. If you would like other users in your organization to be able to use this field, check the Visible to organization checkbox. This is helpful for teams who wish to track cohorts of apps together.
5. Click Create.
   
6. Your new custom field will appear in the right side of the  Add Tags pane.
7. If you wish to add new tags to your custom field at this stage, simply enter the tag name in the New Tag field and hit Enter. If you want to edit or remove any tag, select the edit icon beside the custom field's name. You can also delete the entire custom field from this pane.
8. Select the tag you wish to assign to your selected cohort of apps.
9. If you wish to include sub-apps of your selected apps, check the Tag all unified sub-apps checkbox.
   

   This is an important step if you want to include versions of the app from both the Apple and Google Play store, as well as any region-specific sub-apps that may be associated with your cohort.

10. Click Apply Tag.
11. Refresh the page to see your new field appear in the Custom Fields section of the available filters! You may need to click Display All Fields to see this.
