About this app

See your nervous system actually recover.

Autonomic turns a Bluetooth heart rate strap, or just your finger over your phone's camera, into a full HRV lab in your pocket, then grades every reading against published research thresholds, so you finally 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 and no tracking. Every install starts with 7 days of pro access, then keeps the core free forever.


LIVE 5-MINUTE HRV, DONE RIGHT

• Capture beat-to-beat RR intervals live from a Bluetooth chest strap (like the Polar H10), or with your phone's camera using your finger
• A full screen guided session with a 5:00 ring, live heart rate, and a paced breathing visualizer (4/6 resonance breathing and more)
• 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
• Honest signal quality: artifacts are flagged and corrected, and a noisy reading refuses to fake a score instead of lying to you


EVERY NUMBER GRADED, NO BLACK BOX

• Every number is scored great / good / ok / warning / crash against real thresholds, with no mystery "readiness" black box
• 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


BUILD YOUR PROTOCOL, KEEP YOUR STREAK

• Define your own "clean day": a hydration target, sleep hours, the meds and supplements to take, the triggers to avoid
• Every day is matched against your protocol automatically, so you see at a glance whether you stayed on plan
• Clean days build a streak, with your longest run and a 30 day consistency rate: the discipline that actually drives recovery


TRACK EVERYTHING THAT MOVES THE NEEDLE

• Water, meals and food triggers, medications and supplements, symptoms, activities, sleep, blood pressure and orthostatic stand tests
• Digestion and bowel movements too: the whole picture, not just heart rate
• Make it yours: add your own meds, supplements, activities, symptoms and triggers as custom types


FIND WHAT HELPS OR HURTS

• Analysis across days, weeks and months: spot the salt, sleep, pacing or medication changes that move your numbers
• On-device trigger and symptom trends over time
• Milestones so recovery actually adds up
• Optional: bring your own AI for a deeper written read of your data, or to create a report to share with your doctor


YOUR DATA NEVER LEAVES YOUR PHONE

• 100% offline-first: no account, no cloud, no tracking, no ads
• Everything is stored on device; you own it and can export it anytime
• Reads HRV, resting HR, sleep and blood pressure from Health Connect, and writes back what you log, only when you ask


WHAT'S FREE, WHAT'S PRO

Free forever: journaling (sleep, meds, symptoms, triggers, hydration, meals, activities), manual readings (blood pressure, resting heart rate, episodes), your daily Autonomic Score and outlook, one live HRV capture a day, 14 days of progress charts, and backup and export.

IMPORTANT: Autonomic is a personal journal and education tool, not a medical device. It does not diagnose, treat, or prevent any disease. Always discuss protocol, medication, or supplement changes with your doctor.

* Imported HRV samples from Health Connect now only count sessions that last at least 4 minutes (to improve accuracy of scores shared)
* Improvements to performance and the UI
