Autonomic: HRV & POTS Tracker

New: workout heart-rate zone reports. Track HRV, blood pressure, sleep and stand tests, medically scored and fully private. Built for POTS, dysautonomia and long COVID.

See your nervous system actually recover.

Autonomic turns a heart rate chest strap, your Apple Watch, or even your finger over your camera into a full HRV lab in your pocket, then grades every reading against published research thresholds, so you know whether today was a good day or a warning sign.

Built for the long haul: long covid and post viral recovery, POTS and dysautonomia, ME/CFS, and anyone rebuilding their autonomic nervous system one day at a time.

Free to use, with no account, no ads or tracking. The journal is free forever. Features marked (Pro) below require Autonomic Pro, an optional auto-renewing subscription.

IMPORTANT: Autonomic is a personal wellness journal and education tool, not a medical device, and it provides no medical services: it does not diagnose, treat, or prevent any disease. No external hardware is required; compatible chest straps are general-purpose consumer fitness accessories using the standard Bluetooth heart-rate profile, not medical devices, and require no regulatory clearance for use in any region. Always discuss protocol or medication changes with your doctor.
