Tweaking and AB Testing Your App on the Fly
summary
Shows how to use Firebase Remote Config (with Remote Config defaults + fetch + activate) and Firebase Analytics (set experiment as a user property) to change app constants live, run A/B tests by random percentile or country, and measure conversions. Demo replaces button text, font and color from the console, records experiment group, and reports a measured lift (example 88% vs 54%). Notes practical limits: 12‑hour cache unless overridden, client/server throttles, publish and analytics delays, and strategies for safe rollouts.
