Autonomic: HRV & POTS Tracker

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.
