Autonomic: Measure, Analyze, Monitor, Act

Austin Spaeth The app
Recovery

Everything about autonomic recovery comes down to one loop: measure what's happening, analyze the trend, monitor for warnings, and act. Autonomic is the app built to close that loop: private, offline, and scored against medical thresholds.

TLDRAutonomic is a private, offline iPhone app for tracking autonomic recovery. It closes the loop that every other article on this site points to: it MEASURES your HRV, heart rate, blood pressure and orthostatic readings, ANALYZES them by scoring each against medical thresholds and charting a rolling baseline, MONITORS trends and flags early warnings, and helps you ACT: pacing, finding triggers, and building doctor-ready summaries. No account, no cloud, no data leaving your phone.

Everything comes down to one loop

Read the rest of this site and a single shape keeps appearing. The autonomic nervous system guide says dysautonomia is invisible but measurable. The HRV guide says track the trend, not the day. The recovery guide says turn that trend into decisions. Underneath all of it is one loop:

Measurelog readingsAnalyzescore + trendMonitorwatch baselineActpace + decide
The recovery loop. Autonomic is built to close it: every feature maps to one of these four steps.

Every good intention about recovery breaks somewhere in this loop. You measure inconsistently, so the trend is garbage. You have readings but no way to know if a number is good. You can’t see the baseline through the noise, so you panic or give up. Autonomic exists to keep the loop intact: here’s how each step works.

Measure: capture readings that are actually comparable

A trend is only as good as the readings under it, and the enemy is inconsistency. Autonomic makes consistent capture easy:

  • Log HRV, resting heart rate, blood pressure, oxygen saturation, sleep and more, from whatever devices you already own.
  • Run a guided orthostatic stand test with the timing structure built in, so every test is comparable to the last.
  • Capture live HRV readings directly, and keep symptoms, triggers, meals and activities in the same journal as the numbers.
No new hardware required. A ring, a chest strap, a BP cuff, a pulse oximeter, or two fingers and a clock. Autonomic scores whatever you record. It meets you where you already are.

Analyze: every reading scored against medical thresholds

This is what sets Autonomic apart from a fitness tracker. A raw number is meaningless if you don’t know whether it’s good. So Autonomic scores each reading against medical thresholds (the same framework a clinician’s zones are built on) and tints it by zone, from great to concerning.

Then it does the thing that matters most for recovery: it charts a rolling baseline so you see the trend under the daily noise, exactly as described in the recovery guide. One rough morning never derails you, because the app is always showing you the line, not the dot.

What you logHow Autonomic analyzes it
HRVScored by zone, charted against your rolling baseline
Resting heart rateTracked for the upward creep that signals load
Blood pressureScored against thresholds, sex- and profile-aware
Stand testRise and recovery scored against POTS thresholds
Symptoms & triggersKept beside the numbers so patterns surface

Monitor: see the warning before the crash

Recovery is protected by catching trouble early. Autonomic surfaces an Autonomic Outlook (a daily read on how your system is doing) and keeps your baselines visible, so a sliding trend becomes an early signal to pace back before a crash rather than after. Monitoring is what turns your data from a diary into a guardrail.

Act: turn the trend into decisions

Data is only worth it if it changes what you do. Autonomic helps you:

  • Pace by using your trends as guardrails on your energy envelope.
  • Find your triggers by keeping context next to the numbers, so “why was that a bad week?” becomes answerable.
  • Build a doctor-ready summary: turning months of data into a five-minute doctor conversation your clinician can act on, with optional AI help to structure it.

Private by architecture, not by policy

Your health data is the most sensitive data you have, and it belongs to you. Autonomic is offline-first: everything lives on your device. No account, no cloud sync, no data leaving your phone unless you deliberately export it. Privacy here isn’t a checkbox in settings; it’s how the app is built.

Close the loop. Autonomic scores your HRV, heart rate, blood pressure and stand tests against medical thresholds, charts the trend, and keeps it all private on your iPhone. Get Autonomic →

The bottom line

Autonomic recovery is a loop (measure, analyze, monitor, act) and most people lose it at one of the four steps. Autonomic is the app built to keep it whole: consistent measurement, medical-threshold scoring, trend baselines that cut through the noise, early-warning monitoring, and the context you need to act. Private, offline, and made specifically for people recovering from POTS, dysautonomia and long COVID, so you can finally see your nervous system recover.

Not medical advice. Autonomic is a tracking and journaling tool to help you understand your own data and communicate with your clinician. It does not diagnose, treat, or replace professional medical care.

Frequently asked questions

What does the Autonomic app do?+

Autonomic is a private, offline journal for tracking autonomic recovery. You log readings like HRV, heart rate, blood pressure and orthostatic stand tests, and it scores each one against medical thresholds, charts your trends with a rolling baseline, and keeps your symptoms and triggers alongside the numbers, so you can see whether your nervous system is recovering and what's moving it.

Is my health data private?+

Yes. Autonomic is offline-first and stores everything on your device; there's no account, no cloud sync, and your data never leaves your phone unless you choose to export it. Privacy isn't a setting; it's the architecture.

Do I need special hardware to use Autonomic?+

No. You can log readings from whatever you already have: a chest strap or ring for HRV, a blood-pressure cuff, a pulse oximeter, or even two fingers and a clock for a stand test. Autonomic scores whatever you record; it works with your existing devices rather than requiring new ones.

How is Autonomic different from a fitness tracker?+

Fitness trackers are built for healthy people chasing performance, and they compare you to population averages. Autonomic is built for people recovering from POTS, dysautonomia and long COVID: it scores readings against medical thresholds relevant to recovery, focuses on your personal baseline and trend rather than generic 'normal,' and keeps symptoms and triggers in the same place as the numbers.

Does Autonomic use AI?+

Autonomic can help you turn your tracked data into a structured, doctor-ready summary and get a deeper read on your trends, without sending your health data anywhere it shouldn't go. The AI helps you interpret and communicate your own data; it doesn't diagnose or treat.
