We aim to respond within 24-48 hours, weekdays.
After completing the brief onboarding (name, age, etc.), tap "Start the test" on the final onboarding screen. The test is 27 questions, 15 minutes, across four domains: Pattern recognition, Numerical reasoning, Verbal ability, and Memory. Your answers are recorded automatically — there's no "submit" button.
About 15 minutes. The timer is shown in the top right of each question. You can't pause once you start, so set aside an uninterrupted block.
Yes. Once you subscribe, you can retake the full 27-question test every 14 days to track your score over time. The retest button appears on the Home tab when the cooldown ends.
Both plans unlock the full app. Cancel anytime in Settings — your access continues until the end of the current billing period.

Try these in order:
Training data (streaks, session history) is stored on your device and resets when you delete and reinstall the app. Your subscription, however, is tied to your Apple ID and restores automatically via "Restore purchases."
If preserving your streak across reinstalls becomes critical, let us know — we're considering a cloud-sync option for future versions.
Our test uses validated psychometric item types — Raven-style matrix reasoning, digit span, spatial sequence, verbal analogies — the same families used in clinical IQ assessment (WAIS, Stanford-Binet, ICAR). Your score is calibrated against the standard normal distribution (mean 100, σ 15) using a difficulty-weighted model.
That said, the score is an estimate, not a clinical diagnosis. We're an entertainment + brain training app, not a licensed psychometric service. If you need a clinical IQ assessment for medical or educational purposes, see a licensed psychologist.
We don't make that claim. What daily training does is help you get faster and more accurate at the specific types of cognitive tasks used in the test. Whether that transfers to general intelligence is a debated question in cognitive science. Take the retests, watch your trend over time, and judge for yourself.

Short version: email + onboarding answers + test responses + subscription state. Stored on your device or with our subscription provider (RevenueCat). We don't sell data, don't show ads, don't use third-party trackers.
