About this app

See your nervous system actually recover.

Autonomic turns a Bluetooth chest strap, a Garmin watch, 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 14 days of full access, then keeps the core free forever.


-- 5 MINUTE HRV READING, DONE RIGHT --

• Capture beat-to-beat RR intervals live from a Bluetooth chest strap, Garmin, or with your phone's camera using your finger
• A guided session of paced breathing, 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
• Honest signal quality: artifacts are flagged and corrected, and a noisy reading refuses to fake a score


-- EVERY NUMBER GRADED, NO BLACK BOX --

• Every number is 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


-- 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
• 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, medications and supplements, symptoms, activities, sleep, blood pressure and orthostatic stand tests
• Digestion and bowel movements too: the whole picture, not just heart rate
• Tap a night for its full sleep report: stages, overnight heart rate and breathing, and how it compares with your recent nights
• Add your own meds, supplements, activities, symptoms and triggers


-- FIND WHAT HELPS OR HURTS --

• Insights: an on device read of your own data that finds what is genuinely linked to what, ranks it, and shows the days behind every claim
• Analysis across days, weeks and months, to see what moves your numbers
• Milestones so recovery actually adds up
• Optional: 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
• Everything is stored on device; you own it and can export it anytime
• Reads HRV, resting HR, sleep, workouts and blood pressure from Health Connect, and writes back what you log, only when you ask


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

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