The C19-YRS app can be configured by clinical teams as part of a clinical service, by Universities for research, or used independently through our public-facing applications. Our clinical version of the app is intended for patients registered at a clinical service which has invited them to download the app to manage their condition remotely, complete assessments, and access support resources to improve their health and wellbeing, according to the individual service’s purpose. The app may also be used for research studies who register participants onto the app to take part in projects. If you are using the app as part of a service or project, a member of staff will provide users with their login details or instructions on how to sign up for the app. Please contact a member of staff at your service or project team for support if you get stuck.

Answers for the questions you live with. How much can today take? Is this dip my cycle or a setback? What actually helps? 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 account, no ads, no tracking. 14 days of full access on install, then the journal and live HRV stay free forever. NEW: CYCLE IMPACT TRACKING • See how your cycle moves your HRV, heart rate, symptoms and daily score • Your score, baseline and warnings now account for your cycle, so a dip before your period is not read as a setback • Know your cycle day and phase, and when your next period is likely • Log your period in a tap, or import your history from Apple Health YOUR DAILY PACING BUDGET • Think spoons, but measured: a budget in minutes of effort, fitted to your own history, not a points score • It counts the whole day: workouts, steps, time upright, and minutes above your own exertion line • Standing still counts too, 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 • Optional alerts when you run ahead of pace, near or go over budget, 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 your Journal, widgets, Apple Watch, and in your doctor report LIVE 5-MINUTE HRV, DONE RIGHT • Beat-to-beat RR 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 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 • An early heads-up when your own markers drift: slower heart rate recovery, 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 • One tap captures a POTS episode: baseline, the climb, and 60 seconds of recovery TRACK EVERYTHING, FIND WHAT HELPS • 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 • Insights finds what helps or hurts in your log, on-device, 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, blood pressure and periods from Apple Health, and writes back only what you ask WHAT'S FREE, WHAT'S PRO Free forever: unlimited live HRV captures, cycle tracking, POTS stand tests and episodes, journaling, 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, cycle impact charts, Insights, POTS results and AI doctor reports. It 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.
