Circl Brain Health

Track your brain's recovery — not just your symptoms.

Circl makes brain healing visible. Using a clinician-administered EEG headset and a simple 10-minute test, Circl captures your P300 brainwave signal — one of the most validated biomarkers in neuroscience — and translates it into a Brain Score you can track over time.

Whether you're recovering from a concussion, mTBI, PTSD, or workplace injury, Circl gives your clinician the objective data they need to guide your treatment and know when healing is actually happening.

What Circl measures: Your Brain Score shows where your brain function sits relative to population norms. Your Healing Trajectory tracks how your score changes across every session — making invisible recovery visible for the first time.

Who Circl is for: Circl is used by occupational therapists, concussion clinics, and rehabilitation specialists to support patients recovering from brain-based workplace injuries including mTBI, concussion, PTSD, depression, chronic fatigue, and burnout.

How it works: A clinician administers a 10-minute test using the Circl EEG headset. You wear the headset while completing a simple task on the app. Your brainwaves are recorded, analyzed, and instantly translated into a Brain Score and healing trajectory report — no lab required.

Circl is not a medical device and should not be used to diagnose, treat, or cure any medical condition. Our products and services are intended to support clinician-guided care. Always speak with a qualified healthcare provider about your health and treatment decisions.
