Know how much today can take. Autonomic sets a daily pacing budget for long covid, ME/CFS, POTS and dysautonomia from your own morning readings and history, and turns a chest strap, Apple Watch, Garmin or your phone's camera into a full HRV lab graded against published thresholds. No armband to buy, no account, no ads, no tracking. 14 days of full access on install, then the journal and live HRV stay free forever. YOUR DAILY PACING BUDGET • Think spoons, but measured: a budget for today in minutes of effort, fitted to your own history, not a points score • It counts the whole day, not just what you log: workouts, steps, time upright, and minutes above your own exertion line • Standing still counts too, read from your own stand test, because upright time costs most with POTS • Legs up and breathwork buy minutes back • A pace marker shows where an even day would be by now, so you can ease off before the day runs out • Optional alerts when you run ahead of pace, nearly spend your budget, go over, or your heart rate stays high • PEM arrives late, so every estimate is checked against the next two days, and you see how often it held • On a day that reads as a downturn, no number is published at all • On your Journal, widgets, Apple Watch, and in the report you take to your doctor LIVE 5-MINUTE HRV, DONE RIGHT • Beat-to-beat RR intervals from a chest strap, Apple Watch, Garmin, or your finger on the camera • A guided 5:00 session with paced breathing, live heart rate, SDNN and your beat-to-beat trace • Computed on-device: SDNN, RMSSD, pNN50, PNS & SNS index, stress index, LF/HF, coherence and more • Artifacts are corrected, and a noisy reading refuses to fake a score EVERY NUMBER GRADED, NO BLACK BOX • Every number scored great / good / ok / warning / crash against real thresholds • One daily Autonomic Score across HRV, sleep, symptoms, blood pressure and more • A plain-language outlook, 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 • A guided lie-and-stand test on your Apple Watch or a chest strap, with your live delta against baseline • One tap captures a POTS episode: baseline, the climb, and 60 seconds of recovery TRACK EVERYTHING, KEEP YOUR STREAK • Water, meals and triggers, meds and supplements, symptoms, activities, sleep, blood pressure and digestion • Your own "clean day" streak, with your longest run and 30 day consistency • A sleep report for every night: stages, overnight heart rate and breathing FIND WHAT HELPS OR HURTS • Insights reads your log on-device to find what is linked to what, and how sure it is YOUR DATA NEVER LEAVES YOUR PHONE • Offline-first: no account, no cloud, no ads. Export everything anytime • Reads HRV, heart rate, steps, 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, POTS stand tests and episodes, journaling, manual readings, your daily score and outlook, the Apple Watch HR monitor, 14 days of charts and full export. Autonomic Pro adds the pacing budget and pacing alerts, week / month / year progress, full history, Insights, POTS results and AI doctor reports. Every install starts with 14 days of full access, then one more free week of pacing. Pro is $7.99/month or $49.99/year, billed to your Apple ID and renewing automatically until cancelled. Cancel anytime in your App Store settings. Terms of Use: https://autonomic.care/terms-of-service/ Privacy Policy: https://autonomic.care/privacy-policy/ IMPORTANT: Autonomic is a personal journal and education tool, not a medical device. It does not diagnose or treat any disease, and the pacing budget is an estimate from your own data, not an activity prescription. Always discuss protocol or medication changes with your doctor.

Verdict
The clearest difference is update cadence: Autonomic at every 4 days against SaltStack's every 3 weeks. Autonomic also leads on iOS requirement (15.1 vs 18.6). On price, ads, in-app purchases and device support there is nothing between them.
