Focus Check — ADHD Self-Test

A private, in-browser ADHD self-screening test (18 questions) with saved history, right in your sidebar.

Focus Check is a quick, private ADHD self-screening test that lives right in your Chrome sidebar — no account, no sign-up, no data ever leaving your browser. Struggling to finish tasks, losing track of appointments, feeling restless, or getting distracted mid-conversation? Focus Check walks you through 18 short questions covering the two symptom areas most screening tools look at — inattention, and hyperactivity/impulsivity — and gives you an instant, easy-to-read breakdown of your results. What you get: - A focused, 4–5 minute self-test — one question at a time, no clutter - A clear results screen: overall score, category, and a domain-by-domain breakdown - A saved history so you can track how your answers change over time - A calm, modern glass-style interface designed to feel unintrusive, not clinical Built around your privacy: - Works entirely offline — no servers, no network requests, no analytics, no tracking - Results are saved only on your device using Chrome's local storage - Nothing is ever sent to us or to any third party - Clear all saved results anytime with one tap Important: Focus Check is an informational self-screening tool, not a diagnostic instrument. It's designed to help you decide whether a conversation with a doctor or mental health professional is worth having — it does not replace one. Only a licensed clinician can diagnose ADHD. Whether you're curious, tracking symptoms before an appointment, or just want a fast gut-check, Focus Check gives you a private, no-pressure way to reflect on your attention and focus patterns.
