BUILT INTO EVERY GOODSPEED APP
PostHog Analytics + Feature Flags
PostHog is initialized null-safe at boot (no crash when the key is absent in dev), with auto screen tracking, user identification on sign-in, and a useFlag hook that polls every 60 seconds for server-controlled feature flags with deterministic rollout bucketing.

WHY IT MATTERS
Most mobile app projects spend weeks plumbing the same infrastructure before writing a single line of product code. PostHog Analytics + Feature Flags is one of those cross-cutting concerns that every app eventually needs but almost none get right the first time. Permissions are handled incorrectly, tokens expire silently, or the feature breaks after an OS update nobody tested against.
Goodspeed solves this by shipping posthog analytics + feature flags as a production-grade, tested implementation inside every generated app. The code follows the patterns in the GAS template - the same 246-feature catalog that powers every app we build. Controlled by `features.analytics.enabled` in gas.config.ts. You own the code from day one, can read every line, and can hire any React Native developer to extend it. The build pipeline verifies the feature compiles and routes resolve before the app lands in your repository, so you are not the one catching the integration error at 2 am before launch.
HOW IT IS WIRED
Real code from the GAS template
The excerpt below is lifted verbatim from gas.config.ts in the gas-template repository. This is the code your generated app gets, not pseudocode, not a description of intent.
// Enable this feature in gas.config.ts
export const gasConfig = {
features: {
// Set the relevant flag to true to enable
},
};Source: goodspeed-apps/gas-template → gas.config.ts
HONEST LIMITS
When PostHog Analytics + Feature Flags is the wrong choice
Apps in markets with strict data-residency laws (EU health, government) may need a self-hosted PostHog instance rather than the managed cloud.

Evaluate your use case
Check whether posthog analytics + feature flags aligns with your target audience, platform constraints, and regulatory environment before enabling it.
Audit the config
The `features.analytics.enabled` flag controls this feature. Set it to false in gas.config.ts to disable the feature entirely with no residual code paths.
Seek alternatives
If the built-in implementation does not fit, the generated codebase is standard React Native + Expo code. Any library in the Expo ecosystem can replace the default.
