Why Analytics Now - You're Flying Blind Without It

You already deployed app + payments + security. Analytics converts assumptions into measurable product decisions.

PostHog (already installed)

Event tracking across Android/iOS actions.
Screen flow to detect drop-off points.
Funnels: install -> onboarding -> payment conversion.
Feature flags for controlled rollouts.
A/B testing for UI and onboarding experiments.

Firebase Analytics (add this week)

Installs and acquisition sources.
Screen views and user journeys.
Engagement and retention cohorts.
Demographics: country, device, OS.
Goals/conversions: sign-up and purchases.

PostHog = behavior inside your app. Firebase Analytics = acquisition + usage at scale. Together they give complete visibility.
