User Properties in Firebase Analytics allow you to define and track specific attributes of your users. These properties can help you understand your user base better and segment your audience for more targeted analysis and marketing efforts.

1. User Properties: Attributes you define to describe segments of your user base, such as age, gender, or user preferences.
2. Predefined User Properties: Firebase provides some predefined properties like age, gender, and interest.
3. Custom User Properties: You can define your own properties to capture specific information relevant to your app.

Firebase Analytics includes some predefined user properties that you can set. These properties are standardized and can be used across different Firebase services.

You can define up to 25 custom user properties per project. These properties can be used to capture specific information about your users that is relevant to your app.

Here is an example of how to set user properties in an Android app using Firebase Analytics:

In an iOS app, you can set user properties like this:

• Mistake: Setting too many custom user properties.

  • Tip: Remember that you can only set up to 25 custom user properties per project. Choose properties that provide the most valuable insights.
