Autonomic: HRV & POTS Tracker

About this app

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.

Terms of Use: https://autonomic.care/terms-of-service/ Privacy Policy: https://autonomic.care/privacy-policy/ 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.

Insights (NEW) - A real analysis of your own log, not a set of AI prompts. It finds what changed and what is linked to what across everything you track, rates its confidence in every finding, and leaves out anything it isn't sure of. It all runs on your device. Sleep reports (NEW) - Tap your sleep card to open the whole night: your heart rate and breathing through the night, when each stage happened, and how your schedule and hours compare with your recent nights. Improvements on your Journal - Your Journal now points out real improvements as they happen. Every metric explains itself - Tap the "?" on any card for what a number is in plain terms, and what it means for you.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
