A(rDx)HD
A(rDx)HD
AI-powered ADHD screening through interactive cognitive games. Discover your attention patterns in 15 to 30 minutes from your phone, with no waitlists and no judgment.
Traditional ADHD evaluation can take 6 months to 8 years and cost up to $14,000. We make first-line attention screening accessible to everyone.
Four interactive games measure reaction time, sustained attention, working memory, response inhibition, and visuomotor tracking: thousands of behavioral datapoints, not just self-reported feelings.
Tap to flip ↻Orchard Munch clocks your reaction time in milliseconds. That's fast enough to catch responses your conscious brain hasn't even registered yet.

English, Spanish, French, Arabic, Farsi, Hindi, Urdu, and Chinese, making cognitive health accessible across communities and cultures.
Tap to flip ↻ADHD looks different across cultures. Some languages don't even have a direct translation for "hyperactivity." We built this with that in mind.
Tap to flip back ↺A(rDx)HD is currently a research-stage screening platform. Our long-term mission is to make it a fully validated, regulator-cleared diagnostic tool. Here's where we are right now:
Three years of R&D, presented at international psychiatry conferences, with input from 50+ clinicians.
400+ early user testing sessions in progress; refining the cognitive games and AI interpretation layer.
Planned validation studies against the DSM-5 criteria, ASRS v1.1, Vanderbilt and Conners scales.
Pursuing FDA Software-as-a-Medical-Device (SaMD) classification and equivalent clearances internationally.
Each game targets a distinct attention function. Complete all four to unlock your full cognitive profile.
Dodge asteroids and track debris. Measures sustained attention, reaction time, and target tracking.
Tap to flip ↻Every dodge, every miss, and the split-second before you react all get logged. That data builds your sustained-attention score.
Tap to flip back ↺Follow a firefly as it lights a growing trail across the night sky, then retrace the glowing spots in order. Measures working memory and sequence recall.
Tap to flip ↻The trail grows by one spot every round, so it quietly pushes past the limits of your short-term memory span, which is exactly what we are measuring.
Tap to flip back ↺Control a paddle to break bricks. Measures spatial attention, motor coordination, and visual tracking.
Tap to flip ↻Your paddle position gets sampled continuously, not just on hits. That's what picks up subtle motor-tracking drift.
Tap to flip back ↺Feed a hungry critter only the fruit it wants, and hold back when the wrong fruit or junk pops up. Measures response inhibition and sustained attention.
Tap to flip ↻Every tap, held response, and split-second reaction is logged. Missed target fruit and taps on the wrong items build your inhibition and attention score.

Logging in is required to take the assessment and receive personalized feedback.
Your account is required so we can save your gameplay data, generate longitudinal insights, and let you delete your data on request. We never sell your information.
Before you take the assessment, please read and accept the following. You can withdraw consent at any time from your account settings.
Take a moment to check in with yourself before we start.
For the most accurate results, play all 4 games in one sitting and try not to pause or quit once you begin. Each game also asks you a few quick check-in questions. Coming back on different days to build a steady streak is what sharpens your ADHD tracking over time.
Move your avatar to dodge incoming asteroids and stay alive as long as possible.
Follow a firefly as it lights a growing trail across the night sky, then retrace the glowing spots in order. Measures working memory and sequence recall.
Break bricks with a bouncing ball while managing speed, position, and timing.
Feed a hungry critter only the fruit it wants, and hold back when the wrong fruit or junk pops up. Measures response inhibition and sustained attention.
Move left and right to dodge the falling asteroids. The run comes in three waves, and each wave sends more asteroids your way. We measure your reaction time, accuracy, and consistency.
How it ends: a 30-second timer, shown top-left. Getting hit never ends the run, it just counts against your accuracy, so keep dodging until time runs out.
A firefly drifts across the night sky, lighting up spots one by one to trace a trail. When it finishes, retrace the same spots in the exact same order from memory. Each round adds one more spot, so the trail you have to hold in mind keeps growing. We measure your working-memory span and recall accuracy.
How it ends: after 8 rounds. A wrong answer does not stop the game, the trail just keeps growing to the end.
Control the paddle and break all the bricks with the bouncing ball. We measure paddle accuracy, tracking precision, and how well you anticipate the ball's path.
How it ends: clear every brick, or when your 3 lives run out. Your lives and remaining bricks are shown top-left.
A hungry critter roams a 5 by 5 orchard. Its favorite fruit is shown up top. Fruit keeps popping up all over the grid and each one only stays for a few seconds.
How it ends: after about 40 seconds. Grab as much of the favorite fruit as you can while leaving the junk alone.
Based on your gameplay across four cognitive domains. This is an informational screening, not a diagnosis.
Every score works the same way as the games: out of 10, where higher means a stronger result. Each one combines how you played with the quick check-in answers you gave after each game. Higher scores point to areas of strength, while lower scores are simply areas you may want to explore further with a qualified professional.
Your data stays private, is never sold to advertisers, and you can delete it at any time from your account settings.
Make this space yours, and keep an eye on how your results shift over time.
Make the whole site easier on your eyes and brain. Changes apply everywhere, instantly, and are remembered.
Manage your password, add a private hint, or change your email.

Every time you finish all four games, we save a snapshot so you can watch your attention patterns shift, session to session.
Education, strategies, and trusted support for managing ADHD.
ADHD (Attention Deficit Hyperactivity Disorder) is a neurodevelopmental condition that affects how the brain manages attention, impulses, and executive function. It can show up as inattentive, hyperactive-impulsive, or combined presentations.
Inattentive (difficulty sustaining focus, easily distracted), Hyperactive-Impulsive (restless, acts without thinking), and Combined (both sets of symptoms). Symptoms often look different across ages and genders.
Time-blocking, the Pomodoro technique, body-doubling, externalizing memory via lists and reminders, reducing decision fatigue, and building movement into your day. All backed by real research.
If you've consistently noticed patterns of inattention, impulsivity, or hyperactivity that interfere with school, work, or relationships, a formal evaluation by a psychiatrist, psychologist, or neurologist is the next step.
Structure, clear and consistent expectations, positive reinforcement, and working with the child's school on accommodations are foundational. Avoid framing focus difficulties as moral failings.
A(rDx)HD is developed in partnership with Jahanikia NeuroLab. The games are designed around established cognitive paradigms (continuous performance tasks, sequence memory, visuomotor tracking) that correlate with attention function.
A calm, snappy block puzzle. Drop shapes onto the grid, fill full rows or columns to clear them, and climb through levels that get trickier as you go. Your progress saves automatically, so you can pick up right where you left off.
The game ends only when none of your three shapes can fit anywhere. Your best score and highest level are always saved.
An AI-driven gamified ADHD screening platform built to make first-line cognitive assessment accessible to everyone.
Traditional ADHD diagnosis is slow, expensive, and hard to access. We want to change that.
We're building a future where screening reflects how people actually think and function. Earlier, more accessible, and free from subjective judgment. We combine neuroscience, interactive design, and careful AI to cut misdiagnosis and open up access to reliable screening across communities and cultures.

A(rDx)HD is a research-stage cognitive screening platform. As of the date above, it has not been cleared, approved, or registered as a medical device by the United States Food and Drug Administration (FDA), the European Medicines Agency (EMA), Health Canada, the UK's MHRA, or any other regulatory authority.
We are actively working toward becoming a validated diagnostic tool. Our roadmap includes formal clinical validation studies against established instruments (DSM-5 criteria, ASRS v1.1, Vanderbilt Scales, Conners Scales), peer-reviewed publication of results, and submission for Software-as-a-Medical-Device (SaMD) classification. Until that work is complete, the Service should not be relied upon as if it were validated diagnostic software.
Results from the Service are educational and informational. They reflect how your cognitive game performance compares to patterns observed in research data. They can be a useful starting point for a conversation with a clinician, but they are not, and should not be interpreted as:
If you have concerns about your attention, focus, mental health, or daily functioning, please consult a qualified healthcare professional: a psychiatrist, psychologist, neurologist, or primary care physician.
If you are experiencing a mental health emergency or thoughts of self-harm, please contact your local emergency services or a crisis line immediately. In the United States, you can dial or text 988 for the Suicide & Crisis Lifeline. In the United Kingdom, dial 116 123 for Samaritans. Other regions have equivalent services.
Please use this platform thoughtfully. Do not share your results in ways that could mislead others into thinking they are a diagnosis. Do not use the platform to make consequential decisions about yourself or others (academic, employment, legal, or clinical) without independent professional confirmation.
For questions about this disclaimer: ardxhd@gmail.com, attn: Compliance, Jahanikia NeuroLab LLC.
Each game is built on a research-validated cognitive paradigm with decades of published evidence. We did not invent these tasks; we re-built them as games that work on a phone.
A(rDx)HD is developed in partnership with Jahanikia NeuroLab, an independent neuroscience research lab, and Neuro Health Alliance, a youth-led mental health nonprofit operating in over 120 chapters across 9 countries.
We are running pilot screening sessions with hundreds of users to refine the AI interpretation layer. Planned next steps include formal validation studies against established instruments (DSM-5 criteria, ASRS v1.1, Vanderbilt Scales, Conners Scales), peer-reviewed publication of results, and submission for Software-as-a-Medical-Device (SaMD) classification with the FDA and equivalent international regulators.
A(rDx)HD has been presented at international psychiatry conferences and received input from over 50 clinicians during development. A formal publication describing the methodology is in preparation.
