Autonomic turns your daily HRV, blood pressure, sleep and orthostatic readings into clear, medically-scored signals, so anyone recovering from POTS, dysautonomia or post-viral illness can finally see what helps and what hurts.
Free to download, with 14 days of Pro. After that Pro is $7.99/mo, or stay on the free journal forever.
The loop
You log a few readings. Autonomic does the grading, the trends, and the “what changed”, quietly, on your device.
Capture live HRV, and log BP, orthostatic tests, sleep, meds, triggers and symptoms from a number of Bluetooth devices and Apple Health.
Each reading is broken down into its key metrics, graded against medical thresholds, and rolled into one 0–100 Autonomic Outlook with a confidence level.
Milestones to keep you motivated. Sparklines, zone bands, heat maps and more reveal the patterns moving your recovery up or down.
Get structured prompts packed with your data to share with your AI provider (ChatGPT, Claude, etc) or doctor, so you can find what's working and what's not.
Capture
A guided log built around real autonomic data, not a generic habit tracker. Add a reading and Autonomic knows exactly which fields and thresholds apply.
Scoring
No more guessing whether a reading is “good.” Each metric lands in a clinical zone, from great to crash, and combines into a single daily Outlook with a confidence score that reflects how much you logged.
Tap the score and Autonomic breaks down exactly what helped, what hurt, and how to firm up tomorrow’s number.
Analyze
Switch from a single day to the long view. Zone-banded sparklines show each point in its medical context, with an average baseline so you always know if today beat your own norm.
The moment the room tilts, the data’s already there. Run the stand test, catch an episode as it happens, or just keep an eye on your heart rate — no phone, no waiting, nothing to miss.
iPhone + Apple Watch. On Android the same stand test and episode capture run in the app itself, using a Bluetooth chest strap or your phone’s camera.
Lie down and rest quietly. We’ll tell you when to stand.

Wellness screening only. HR-based, does not measure blood pressure, and is not a diagnosis. Discuss with your doctor.
First we’ll capture your heart rate before the transition.

Autonomic assembles your data into a rich, structured prompt, then hands it to the model you already trust. Trends, triggers, and a clear “here’s what to tell your doctor,” generated locally and copied in one tap.

Identify what is working and what is not.
Pick a report, copy the prompt, and paste it into ChatGPT or Claude to see the kind of read-out Autonomic gives you. It runs on realistic sample data, so you get a real feel for the reports before you ever log a thing.
Momentum
Recovery is slow and easy to miss. Autonomic tracks clean-day streaks and earns you milestones the moment your data crosses a real threshold, so progress beyond the daily number stays visible.
Privacy by architecture
No account. No cloud. No tracking. Autonomic stores everything in local storage on your device, computes every score and report offline, and gives you a one-tap JSON export you fully control. It can even back up automatically to your own iCloud, so your data stays with you, not us. Privacy isn’t a setting here, it’s how the app is built.
Depth, on tap
The surface stays calm. Underneath sits the instrumentation serious recovery needs.
Coherence %, LF/HF/VLF power bar, RMSSD, pNN50 and baroreflex peak.
Side-by-side stand-test stats and extreme-event flags.
Systolic and diastolic visualized against healthy ranges.
How last night’s sleep bends today’s autonomic score.
Pricing
Log everything, score every day, read your HRV as often as you like, keep your data, pay nothing. Pro is for when you want to go deeper: your whole history, Insights, POTS testing and AI reports.

Autonomic vs Welltory
The same clinical grade HRV from your Apple Watch or a chest strap, without the tracking, the lock in, or the $119.99 a year bill. And a journal that stays free.
WelltorySame readings. Your data, your AI, fully exportable, for less than half the price, on top of a journal that costs nothing at all.
Questions
The app is free to download and your journal is free forever, with no account and no ads. Autonomic Pro is $7.99/month or $49.99/year and unlocks the deep-analysis tools. Every install opens with 14 days of Pro, no card, so you can try all of it first. Your data is always private: stored on your device, never sold, never sent to a server.
Free covers the daily journal, your manual readings, your daily Autonomic Outlook, unlimited live HRV capture with no daily cap, the Apple Watch heart-rate monitor, backups and export, plus 14 days of charts. Pro adds your full history, Insights, POTS testing and episode tracking, and AI insight and doctor reports. There’s a full breakdown in the pricing table, and the same table lives inside the app.
Completely. It’s a fully offline app on both iOS and Android. Scoring, trends and reports are computed locally, so it works anywhere, no signal required.
POTS, dysautonomia, long COVID and post-viral or post-illness recovery, anywhere daily HRV, heart-rate and orthostatic patterns matter.
Yes. Autonomic is available now on both iPhone (App Store) and Android (Google Play), at the same price, with the same private, offline design. One honest difference: the Apple Watch companion app is iPhone-only. On Android the stand test, episode capture and HRV readings all run in the app itself, using a Bluetooth chest strap or your phone’s camera, and it reads your sleep and workouts from Health Connect the way the iPhone build reads Apple Health.
No. Autonomic can measure your HRV with nothing but your phone: rest a fingertip on the rear camera for three minutes and it reads your pulse directly. You can also type readings in by hand from any source. That said, a Polar H10 chest strap, an Apple Watch or a blood pressure cuff make it far more powerful, the more data you feed it, the better you understand how your body is doing.
Autonomic builds a structured analysis prompt from your data over a date range. You copy it into Claude, Gemini or ChatGPT, the text is generated on-device, nothing is sent automatically.
No. Autonomic is a personal tracking and reflection tool. It helps you organize data and conversations, but it doesn’t diagnose or treat. Always work with your clinician.
The story behind Autonomic
For more than four years, I’ve been living with long COVID. It started with blood pressure that spiked out of nowhere, a heart that raced the moment I stood up, brain fog that swallowed whole days, and a long list of symptoms that never quite fit together. I saw specialist after specialist in cardiology, neurology and beyond, and kept leaving with the same thing: no real answers.
So I started tracking it myself: HRV, blood pressure, heart rate, sleep, what I ate, the days I crashed. Slowly, patterns surfaced. I found small things that made life more livable, and I got a little better. I’m not healed, and I won’t pretend otherwise. But over the two years I’ve used my own early version of Autonomic, I’ve been able to see what genuinely helps and reach a far better place than I’d been in for a long time.
I’m not a doctor. I’m not an expert. I’m just someone on this road, in South Carolina, raising six kids, figuring out my own recovery one reading at a time. Autonomic is the tool I built to make sense of it. If it helps you spot your own patterns, find your own answers, and feel a little more in control of your journey too, then it’s done exactly what I hoped.
