The answer to both trends is Google Analytics 4, which combines the world of WEB and APP. Thanks to this, you can measure and analyze user interactions in a mobile application and on the company's website within one tool . And all this thanks to improved recipient identification. Universal Analytics was based on the device identifier (cookie), while GA4 uses two more sources of data acquisition:

Google Signals – automatically collected data from users who have enabled online advertising personalization ;
User ID – unique user identifiers provided by marketers.
This data synergy is an important step towards multi-level analysis that was not available in previous versions of Google Analytics.
