About this app

How old do you think your mind really is?
"Mental Age Test" reveals your mental age as one big number after just 3 minutes of questions and mini-games.

■ Your mental age, analyzed 6 ways
Playfulness, Calm, Kindness, Patience, Outlook and Young Brain.
Your mental age is analyzed from these six angles.
"Playfulness: 9. Patience: 52." You see exactly where you're young and where you're grown-up,
and you'll find yourself nodding: "Yep, that part of me is still a kid."

■ Not just questions: how you play counts too
Pop bubbles, tap the circle that lights up, hold off pressing a button for 10 seconds, guess 10 seconds without a clock.
Mini-games that read your mind come between the questions.
Can't wait and press too soon? That's part of your mental age too.

■ A title that sums you up at a glance
"A Player in Grown-Up Clothes"
"Master of Doing It Tomorrow"
"Second Time Around"
"The Mischievous Elder"
You get a title, a portrait of what you're like, and "So true" moments that make you laugh.

■ Find out why you got that age
"Start crying too" made you 5. Holding off Don’t Press for 6.3 seconds made you 41.
Your answers and scores show the moments that made you younger and the moments that made you older.
Strengths, a gentle heads-up, a word from your inner self and compatible mental ages: there's a lot to read.

■ Play inspired by real research
Patience, reading feelings from faces, sensing time.
The mini-games are inspired by research on age and the mind, and your result tells you about the study behind it.

■ Even more fun next to your real age
Enter your real age to see the gap (it's optional).
"20 years older than I am!" or "Wait, I'm 9?" Either way, it's a fun result.

■ Fill up your Type collection every time you play
The questions change every time. Play again and you might get a different age.
A graph tracks how your age moves, and every type you meet joins your collection.
On the home screen, Today’s “Huh!” brings you a new fun fact about age and the mind every day.

■ Compare with friends
Share your result as an image ready for Stories or X.
"How old was your mind?" is the perfect conversation starter.

■ Perfect for you if you...
・Want to know how old your mind really is
・Get told you're "so mature" or "such a kid"
・Want to compare results with friends, family or your partner
・Love personality quizzes and fun tests
・Want something fun for a 3-minute break

■ Play with peace of mind
No name or birthday needed. No sign-up: open the app and start right away.
Your real age is optional, and if you enter it, it stays on your device.
Available in English, Spanish, Portuguese, French, German and more.

※ This test is for entertainment. It's inspired by research, but it is not a medical or psychological test and does not measure intelligence, personality or health.
