Best ADHD Test Apps (2026)
Quick answer: The best ADHD test apps in 2026 are ADHD Online (best for formal assessment), the ASRS screener (best free screening), Inflow (best for CBT-based support), Numo (best for daily strategies), and Helel (best for a personality-aware screening plus a live-video companion). Screeners indicate possibility only — a diagnosis requires a licensed clinician.
How we evaluated ADHD test apps
An important distinction up front: a screening tool is not a diagnosis. Only a qualified clinician can diagnose ADHD. We rated each app on whether it's honest about that, plus quality of the screening instrument (validated tools like the ASRS), next-step guidance, free access, and ongoing support after the result. We favor apps that point you toward professional evaluation rather than promising answers they can't give. Updated for 2026.

The picks in detail
ADHD Online — best for formal assessment
ADHD Online connects you to licensed clinicians for a structured, diagnostic-grade evaluation (availability varies by region). This is the right route if you want an actual diagnosis, not just a screen. Paid. Best for people ready for a formal assessment.
ASRS screener — best free screening
The Adult ADHD Self-Report Scale, developed with the World Health Organization, is a short validated screener widely used as a first step. Many free apps and sites host it. Best for a quick, credible indication of whether to seek professional evaluation.
Inflow — best CBT-based support
Inflow offers a structured, CBT-informed program for managing ADHD traits day to day — focus, procrastination, emotional regulation. Free trial, then subscription. Best for people who already suspect or know they have ADHD and want ongoing tools.
Numo — best for daily strategies
Numo blends bite-size strategies, habit tools, and a supportive community in a gamified format that suits ADHD attention patterns. Free with paid extras. Best for lightweight daily support.
Helel — best personality-aware screening plus companion
Helel includes an ADHD screening component within a broader clinically grounded personality assessment (Big Five/OCEAN, HEXACO, NEO PI-R style measures, around 300 data points). It's explicit that screening indicates possibility, not diagnosis. What's distinctive is what follows: you approve your profile and gain a live-video AI companion that adapts to your traits — helpful for talking through focus struggles, body-doubling on tasks, or simply feeling understood. Free test; free to start. Best for people who want a personality-aware screen plus ongoing support. Helel is not medical care and does not diagnose ADHD.
How to choose
- You want a real diagnosis: ADHD Online or your GP — start there.
- You want a quick free screen: the ASRS.
- You want daily coping skills: Inflow or Numo.
- You want screening plus a supportive companion: Helel.
Understanding your broader trait profile adds context; low conscientiousness, for example, can overlap with attention challenges — see our conscientiousness explainer and our answers hub. For focus-related support, see our AI companion for focus guide.
A supportive note: screeners are a starting point, never a diagnosis. If ADHD is affecting your work, relationships, or wellbeing, please seek a professional evaluation. Helel supports understanding and connection but does not replace medical care.
Try it free: Take Helel's free clinical assessment — including an ADHD screening component — and meet a live-video AI companion that adapts to your personality and helps you talk through focus and follow-through. Start at /assessment.
Frequently asked questions
Can an app diagnose ADHD?
No. Apps and online screeners like the ASRS can only indicate whether ADHD is possible. A formal diagnosis requires evaluation by a qualified clinician who reviews your history, symptoms, and functioning.
What is the most reliable free ADHD screener?
The ASRS (Adult ADHD Self-Report Scale), developed with the World Health Organization, is a widely used and validated free screening tool. Treat a positive result as a prompt to seek professional evaluation, not as a diagnosis.
Does Helel diagnose ADHD?
No. Helel includes an ADHD screening component within its personality assessment and is explicit that this indicates possibility, not diagnosis. It offers supportive companionship, not medical care.
