Dennis understands the importance of using an analytics solution for his app, but he doesn't know which one to use. Which solution is Google's best-in-class app analytics solution?

Google Analytics for Firebase is Google's current, best-in-class app analytics solution. It provides robust, free, and unlimited reporting for app usage and user engagement, integrating seamlessly with other Firebase features and Google Ads. Codeless tracking with Google Play offers some basic insights but lacks the depth and customization of Firebase. App attribution partners focus primarily on tracking ad campaign effectiveness and user acquisition, not comprehensive app analytics. Google Analytics for Mobile is an outdated solution; its functionality has been largely superseded and integrated into Google Analytics for Firebase.
