Not medical advice
Northsignal is for general education about ADHD and focus health. It does not diagnose, treat, or prescribe, and it is not a telehealth provider or affiliated with one. Talk to a licensed clinician about evaluation and treatment. Full disclaimer
Free tools. Honest limits.
Screeners, quizzes, and prep checklists built on the same rule as everything here: education only, sources shown, limits stated. Every tool tells you what it can — and can't — do.
ASRS v1.1 Self-Screener
The six-question adult ADHD screener developed with the World Health Organization — presented with plain-language scoring, an honest results screen, and a printable summary to bring to a clinician. A screener suggests whether evaluation is worth pursuing; it never diagnoses.
All tools
Built in the open, one at a time. Tools marked "coming soon" are in the workshop — newsletter subscribers hear first.
Signal or Noise? — the quiz
Ten real claims about ADHD from our library. You guess Signal, Weak signal, or Noise — we reveal the verdict and the research behind it. Learn the library the fun way, then share your score.
Appointment Prep Builder
Answer a few questions about your situation and get a personalized, printable one-pager for your evaluation: your examples, your history notes, your questions for the clinician. Walk in prepared.
Weekly Pattern Log
A simple structured log — when focus, restlessness, or impulsivity caused problems, and in which settings. Not a score, not a diagnosis: organized notes that make a clinical conversation sharper.
Focus Timer
A timer built for time blindness: visible elapsing time, gentle start prompts, and honest session stats. No streaks, no guilt mechanics — just structure you can see.
