This is not a diagnostic or medical tool. It's a structured way to reflect on your own patterns. Only a qualified health professional can assess or diagnose ADHD.

A self-check for the curious

24 short questions about how often things happen to you, plus five about context. Answer for the last six months, as you are on a typical day. To keep things running smoothly, there are 100 self-checks available each day.

  • Private by design. Your answers are sent once to be scored, then thrown away. They are never stored, logged or tied to you, there are no account needed, and your PDF is made on your device.
  • Built on the official criteria. The first 18 questions map one-to-one onto the 18 DSM-5 symptoms of ADHD, rewritten in plain adult language. Six more cover the executive-function and emotional patterns described by Dr. Thomas Brown.
  • You get a dashboard and a PDF. See how your answers line up, which channels stand out, practical ideas, and a report you can bring to a doctor.
