Which tool could you use to collect and send data from a mobile app to a Google Analytics 4 property?

Using the Firebase SDK is the most appropriate way to collect and send data from a mobile app to a Google Analytics 4 property. Firebase is specifically designed for mobile app development and provides a comprehensive set of tools, including the Firebase SDK, which allows developers to integrate analytics directly into their apps. This integration facilitates tracking user interactions, events, and app performance metrics, which are then sent to GA4 for analysis.

Firebase SDK not only ensures that data is collected in a structured manner, compatible with GA4's event-based data model, but it also supports various mobile platforms such as Android and iOS. This makes it easier for app developers to implement and maintain analytics without requiring extensive knowledge of web tracking techniques.

In contrast, Google Tag Manager is generally used for managing marketing tags for websites and might not be the best fit for mobile apps, particularly for deep integration. Google Ads is primarily an advertising platform and is not designed for data collection from app users. Google Data Studio is a data visualization tool, which does not collect data but rather serves to create reports and dashboards based on the data already collected in GA4.
