What is Firebase Analytics?

Firebase Analytics (now called Google Analytics for Firebase) is a free, unlimited analytics solution built into Firebase for mobile and web apps. It automatically logs 25+ predefined events (app_open, session_start, first_open, user_engagement, screen_view) and custom events you define. Key features: (1) User properties — define attributes for user segments (age, location, subscription tier); (2) Funnel analysis — visualize conversion paths through your app; (3) Cohort analysis — track user behavior over time; (4) Audience targeting — use Analytics audiences to target Firebase Remote Config, In-App Messaging, and FCM campaigns; (5) BigQuery integration — export raw event data to BigQuery for custom analysis; (6) Attribution — tracks which marketing campaigns drive installs and conversions; (7) Crash reporting integration — Crashlytics correlates crashes with user cohorts. Analytics data informs product decisions, marketing spend, and feature prioritization.
