How many questions should an onboarding personalization quiz ask?
Across 119 quiz apps, the average is 3.9 captured question screens with a p90 of 10 and a long tail to 65.[1] Don't anchor on the median of 1 — it reflects apps with only one or two captured quiz screens, not one-question quizzes.[1] For a real personalization quiz, plan for roughly 4 to 10 questions and validate depth against your vertical.
Quiz apps average 3.9 question screens (p90 of 10, max 65) — Lazyweb Research, July 2026.
The distribution
Across 119 quiz apps, captured question screens per app average 3.9, with p90 at 10 and a maximum of 65.[1]
The median is 1 only because 62 apps have a single captured quiz screen. The methodology explicitly warns against headlining that median — use the average, the p90, and the leaderboard to characterize real depth.[1]
How to apply it
If you want light personalization, 2 to 4 questions matches the modal cluster (33 apps).[1] If you want a full quiz-to-plan flow, the depth players sit at 10+ (13 apps).[1] Going past ~10 questions puts you in the top decile — justify every screen, because each one is a drop-off opportunity.
Map each question to a downstream personalization it drives. If a question doesn't change the plan, feed, or paywall, cut it.
Caveats
These are captured question screens from LLM vision descriptions (~94% coverage), not a guaranteed count of every question a user answers.[1] Apps with a single captured screen may run longer quizzes that weren't fully captured, so the low end is a floor. Use the average (3.9) and p90 (10) as your planning band, not the median.
