Autonomic: HRV & POTS Tracker

Now works with Garmin: capture HRV from your Garmin watch, chest strap, Apple Watch, or phone camera. Private by design, nothing ever leaves your phone.

See your nervous system actually recover.

Autonomic turns a chest strap, Apple Watch, Garmin or your finger over the 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 nervous system one day at a time.

Free to use, with no account, no ads or tracking. Every install starts with 14 days of full access, then keeps the core free forever.

-- 5 MINUTE HRV READINGS, DONE RIGHT --

• Capture beat-to-beat RR intervals from a chest strap, Apple Watch, Garmin or your iPhone's camera with your finger • A guided session of paced breathing (4 in/6 out), showing live heart rate, SDNN and your beat-to-beat trace as the reading runs • Minimize a reading and it keeps running while you use the rest of the app • Every metric computed on-device: SDNN, RMSSD, pNN50, mean RR, PNS & SNS index, Baevsky stress index, VLF/LF/HF power, LF/HF, coherence, and more

-- EVERY NUMBER GRADED, NO BLACK BOX --

• Every number scored great / good / ok / warning / crash against real thresholds • One daily Autonomic Score that rolls up HRV, sleep, symptoms, blood pressure and more • A plain language outlook for the day: what your body is ready for, from a full workout to a rest day • An early heads up when your own markers drift: slower heart rate recovery, a higher resting or overnight heart rate, a bigger standing rise

-- POTS TESTING ON YOUR WRIST: THE APPLE WATCH APP --

• A guided lie and stand test on your watch: rest, stand when it taps you, and watch your live delta against baseline • Haptic alerts the moment your heart rate climbs 30+ bpm over baseline • One tap on the watch complication starts a POTS Episode capture: baseline, the climb, and 60 seconds of recovery • A live HR monitor for symptomatic moments, with a rolling average and spike alerts

-- BUILD YOUR PROTOCOL, KEEP YOUR STREAK --

• Define your own "clean day": hydration, sleep hours, the meds to take, the triggers to avoid • Clean days build a streak, with your longest run and a 30 day consistency rate

-- TRACK EVERYTHING THAT MOVES THE NEEDLE --

• Water, meals and food triggers, meds and supplements, symptoms, activities, sleep, blood pressure, stand tests and digestion • Tap a night for its full sleep report: stages, overnight heart rate and breathing, and how it compares with recent nights

-- FIND WHAT HELPS OR HURTS --

• Insights: an on device read of your own data that finds what is linked to what, and how sure it is • Analysis across days, weeks and months, to see what moves your numbers • Bring your own AI for a deeper read, or a report for your doctor

-- YOUR DATA NEVER LEAVES YOUR PHONE --

• 100% offline first: no account, no cloud, no tracking, no ads • Stored on device; you own it and can export it anytime • Reads HRV, resting HR, sleep, workouts and blood pressure from Apple Health, and writes back only what you ask

-- WHAT'S FREE, WHAT'S PRO --

Free forever: unlimited live HRV captures, journaling (sleep, meds, symptoms, triggers, hydration, meals), manual readings, your daily Autonomic Score and outlook, the Apple Watch & Garmin heart rate monitor, 14 days of charts, and full export
