Experiments
Onboarding-scoped feature flag exposures from
experiment.exposed events with
surface = 'onboarding'. Each
section is a single experiment with its per-variant funnel —
exposed → started → completed — and a two-proportion z-test
on the completion-rate diff vs the next-best variant.
No experiment.exposed events
with surface = 'onboarding'
in the last 90 days.
When a feature flag tagged with the onboarding surface is evaluated by the iOS app, a row appears here.
Notes
-
"Started" means the user, after exposure, emitted any
onboarding.step_viewedoronboarding.choice_selected. For most exposures this is ≈100% — exposures are usually fired on first paint of an onboarding screen, so the screen view follows immediately. A low started rate is a tell that the flag is being evaluated outside an onboarding session (e.g., a refresh in Settings). - Significance is a two-proportion z-test (|z| ≥ 1.96 → p < 0.05). This is the bar in-app today; switching to a Bayesian credible interval is a Phase 5+ call.

Only experiments with
surface = 'onboarding'appear here. Cross-surface experiments live in PostHog Insights — this page intentionally narrows.
