Is there a free ADHD attention test online?

No free online test can tell you whether you have ADHD; a diagnosis comes from a professional who looks at your history, symptoms across settings and other possible causes. The CDC (updated 2026) puts it plainly: there is no single test to diagnose ADHD. What a free attention test can do is show how you perform on a few tasks, so you have something concrete to watch or talk about.

We make Attention Age, a five-minute attention test for iPhone, and we built it to say what it isn't on the first screen. Updated November 2026.

A mini story: the 2 a.m. search

A 34-year-old project manager misses a third deadline in a month and, late one night, types "free ADHD test online" into his phone. He finds a twelve-question quiz that tells him he's "highly likely" ADHD and offers a paid report. He doesn't buy it. Instead he reads how diagnosis really works: a professional asks about symptoms that started in childhood and show up at home as well as at work, and rules out look-alikes like poor sleep or medication side effects.

So he does two things. He writes down specific examples, school ones included, and books a GP appointment. And he takes a five-minute attention test once a week for a month, same time, same chair, because he wants to see whether his worst weeks line up with his worst sleep. They do, partly. The test didn't answer his question; it made his notes better.

An attention score is a note for the appointment, not the appointment.

ADHD test questions people ask

Is there a free ADHD test online that is accurate?

No online test can diagnose ADHD. The CDC (updated 2026) says there is no single test to diagnose ADHD, and Mayo Clinic (2023) says no single test can confirm it. Online questionnaires and attention games can help you notice patterns to bring to a professional.

Who can diagnose ADHD in adults?

A primary care provider or a mental health professional such as a psychologist or psychiatrist, according to the CDC (updated 2026) and NIMH (2024). They usually gather your history, may use rating scales, and check for other causes.

Is Attention Age an ADHD test?

No. Attention Age is an entertainment and self-practice app. Its Attention Index reflects how you did on three tasks on your phone. It is not compared with any population and is not a medical, clinical or diagnostic test.

Can a computer test be part of an ADHD assessment?

Sometimes, as one tool. The NHS (reviewed 2025) notes a specialist assessment for children and young people may include a computer-based test, alongside talking about symptoms and daily life. It is never the whole assessment.

Why do adults need to remember childhood for an ADHD diagnosis?

Because symptoms have to start early. NIMH (2024) explains that diagnosing ADHD in adulthood is complicated by the need to show symptoms before age 12, so it relies heavily on past reports of behavior.

What can a free attention test actually tell me?

How you performed on specific tasks, on that day, on that device. Repeated under the same conditions, it can show your own trend. It cannot tell you why your attention is the way it is.

This is general information, not medical advice. Talk to your clinician.

Honest limits of Attention Age

One design decision we made: we left out every comparison with other people: no norms, no percentiles, no "you scored better than 70%". A number compared with strangers invites self-diagnosis; a number compared with your last Sunday doesn't.

Start on your iPhone with a baseline

Not a diagnosis. Five minutes, three tasks, a number to watch and bring along. Start on your iPhone.
