About

Upright

Upright turns the chaos of POTS and dysautonomia into a pattern you can see, and hand to your doctor. POTS is invisible and exhausting: dizziness, brain fog, racing heart and fatigue that come and go with no obvious cause. Upright tracks the things that actually move the needle, in one simple daily loop. STANDING HEART RATE TEST Record your NASA lean test: resting heart rate lying down and peak heart rate standing. Upright flags the rise of 30 bpm or more used to define POTS and charts your trend. Add blood pressure readings to the same test: lying, then each standing measurement. SALT, FLUIDS & ELECTROLYTES One-tap logging toward your daily sodium and fluid targets, with progress rings. SYMPTOMS & TRIGGERS Log episodes, severity and triggers such as heat, standing, meals and your menstrual cycle. On a bad day, ask Siri to log a symptom in Upright without opening the app. MEDICATION REMINDERS Add midodrine, fludrocortisone, salt tablets or beta blockers with their dose times. Upright reminds you when each dose is due and tracks your adherence. HISTORY & TRENDS Browse every day you logged and see how your symptoms line up with low-salt days. DOCTOR-READY REPORT Standing heart rate trends, symptom frequency, medication adherence and salt and fluid compliance: the evidence that changes an appointment. YOUR DATA NEVER LEAVES YOUR PHONE No account, no cloud, fully offline. For everyone managing POTS, dysautonomia, MCAS, EDS, long COVID and chronic illness. UPRIGHT PRO PDF and CSV doctor reports, heart rate from Apple Health for your stand test, full trigger correlations and unlimited history. Start with a 7-day free trial on the annual plan. Invite a friend and you both get 30 days of Pro free. MEDICAL DISCLAIMER Upright is not a medical device and does not diagnose, treat or prevent any condition. Always consult your doctor or a qualified healthcare professional before changing your salt, fluid or medication routine. If you faint and are injured, have chest pain or feel seriously unwell, seek emergency care.
