Tracking & Analytics

2 Min. reading time App-Funktionalitäten

Tracking & Analytics in a mobile app means that user behavior is measured and analyzed—for example, which pages they visit, which buttons they tap, or how often they open the app. The goal is to better understand user behavior, improve the app, optimize marketing, and continuously enhance the user experience. Data protection and transparency play an important role in this process.

🔧 Technical Explanation

    • Forwards data to other tools (e.g., Amplitude, Mixpanel, Google Analytics)
  4. Mixpanel / Amplitude
    • In-depth user analysis
    • Funnels, retention, A/B testing
    • Behavior-based targeting (e.g., push notifications only to active users)
