Is this a real IQ test?

BrainRank is designed for entertainment and self-assessment. Your score is calculated using a statistical model based on the normal distribution (mean=100, SD=15). It is not a clinical diagnostic tool.

How is my score calculated?

Your score is based on accuracy and response speed across five cognitive dimensions: Pattern Recognition, Logic, Sequences, Spatial Intelligence, and Verbal Aptitude. Harder questions are worth more points, and faster correct answers earn a time bonus.

What does BrainRank Premium include?

Premium is available as a monthly or annual subscription and unlocks the full 40-question assessment, a detailed cognitive profile with personalized strengths and weaknesses, per-category percentile breakdowns, and actionable improvement recommendations.

How do I restore my purchase?

Open the paywall screen and tap "Restore Purchase" at the bottom. This will check your App Store account for existing purchases.

Can I retake the quiz?

Yes! You can take the quiz as many times as you like. Questions are randomly selected from a large bank, so each session is different. Your history is saved on the home screen.

Is my data private?

Yes. All quiz results are stored locally on your device. We do not collect any personal data, and no information is sent to our servers. See our Privacy Policy for details.
