Meet your new heart health companion. POTS Buddy is the Apple Watch app built *with* the POTS and dysautonomia community in mind — not the other way around. Whether you're navigating daily symptom flares, preparing for a doctor's appointment, or just trying to understand what your heart is doing, POTS Buddy is right there on your wrist. **REAL-TIME HEART RATE MONITORING** Your Apple Watch already tracks your heart. POTS Buddy turns that data into something meaningful. See your heart rate, beat-to-beat changes (delta), and trend direction at a glance — color-coded so you always know where you stand without decoding numbers. **POTS STANDING TEST** The guided standing test walks you through a clinically-informed sit-to-stand protocol right from your wrist. Lie down for 5 minutes, then stand for 10 — POTS Buddy records your heart rate at key intervals (1, 3, 5, and 10 minutes) and shows you the delta. Share the results with your cardiologist or keep them for your own records. **SMART ALERTS THAT ACTUALLY MAKE SENSE** Set your own alert thresholds based on your body, not generic defaults. POTS Buddy uses two alert levels — a gentle heads-up for elevated readings, and an urgent alert for extreme spikes — so you're informed without being overwhelmed. Level 1 alerts quietly dismiss themselves after 60 seconds. Level 2 stays until you're ready to acknowledge it. **SYMPTOM LOGGING ON THE GO** Feeling dizzy? Chest fluttery? Log symptoms directly from your wrist in seconds using the Apple Watch Digital Crown. No fumbling with your phone, no interrupting your day. Every log is timestamped and ready when you need it. **CUSTOMIZABLE WATCH FACES** Make it yours. Choose from multiple themes — including a clean Time & Date only face for those moments when you just need a break from the numbers. Because sometimes the most helpful thing is *not* watching your heart rate. **EXPORTABLE CHARTS & REPORTS** See your heart rate trends visualized in beautiful charts, then export everything — graphs, CSVs, and PDF reports — for your care team. Walk into your next appointment with data your doctor can actually use. **PRIVACY THAT ACTUALLY MEANS SOMETHING** We don't want your data. Seriously. Everything POTS Buddy collects stays on your device. No accounts, no cloud sync, no third-party sharing. Your health information is yours — full stop. **DESIGNED FOR REAL LIFE WITH POTS** We know that anxiety about heart rate can *cause* heart rate spikes. POTS Buddy is designed to be reassuring, not alarming. Calm colors, supportive language, and customizable sensitivity mean the app works *for* you — not against you. --- POTS Buddy works with iPhone and Apple Watch (Series 4 or later, watchOS 8+). HealthKit integration keeps your data in sync with Apple Health. *POTS Buddy is a wellness tool, not a medical device. Always consult your healthcare provider for medical advice.* --- **Your heart. Your data. Your choice.**
