POTS & Dysautonomia

A symptom and vitals diary for Postural Orthostatic Tachycardia Syndrome (POTS) and the wider dysautonomia family — orthostatic intolerance (OI), including the post-viral and long-COVID onset many patients report.

Capture what your cardiologist or neurologist asks about:
• Supine and standing heart rate for orthostatic comparison — auto-fills from Apple Watch/Health when you have one, or enter it yourself
• Symptom episodes — dizziness, palpitations, brain fog, fatigue and more — with severity
• Fluid intake with one-tap amounts, and caffeine/alcohol when relevant
• The COMPASS-31 autonomic symptom questionnaire, built in
• Triggers (heat, standing, meals, exertion), optional local temperature/humidity capture, medications, treatments, and notes
• Time-of-day patterns derived automatically from when your symptoms actually happen

Insights charts trend heart-rate deltas, symptom severity, and daily patterns; PDF reports and CSV export bring hard numbers to appointments — including for the EDS and MCAS overlaps common in this community.

Log from your wrist: an Apple Watch companion app is included for quick one-tap entries that sync to your phone.

Your data stays on your device — no account, no sign-up, and your health information is never uploaded to our servers. Export everything anytime as CSV or a PDF report.

This app is a personal tracking journal. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Always consult your clinician about your care.

Heart-rate autofill reads from Apple Health with your permission; if it doesn't appear, the in-app help link in the Heart Rate section walks through the Health/Watch settings to check.
