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.**

Chronic pain is hard to describe in an eleven-minute appointment. Vaely is a pain and symptom tracker that keeps the record for you and turns it into a report your doctor can read. LOG IN SECONDS, EVEN ON A FLARE DAY Say it or tap it. "Everything hurts, took two ibuprofen, barely slept." One sentence becomes a journal entry. On days when a sentence is too much, quick-log tiles and "same as yesterday" take one tap. On iPhones with Apple Intelligence, Vaely picks out the symptom, severity, medication and mood from what you said and shows them to you before anything is saved. On every other iPhone your words are saved as you said them, and you set the severity yourself. A REPORT YOUR DOCTOR CAN USE Choose a date range and Vaely builds a Doctor Report PDF: a summary first, then charts, medication changes and your own words. Bring it to the appointment, or share it with a caregiver. SEE WHAT CHANGED Severity over time, how often you logged, and a summary of each week: which symptoms and medications kept coming up. With Apple Intelligence, Vaely also points out patterns in your own entries. Observations only. Never predictions, never diagnoses. ON YOUR WRIST The Apple Watch app logs a symptom with the Digital Crown, or takes a dictated entry. With your iPhone in reach, you review it on your wrist before it is saved. TRACK WHAT YOU ACTUALLY HAVE Chronic pain, fibromyalgia, migraine, endometriosis, PCOS, rheumatoid arthritis, lupus, Crohn's disease, diabetes and ADHD are built in. Add any other condition by name: POTS, EDS, long COVID, IBS, ME/CFS, MS. Pro lets you define your own measures too. MEDICATION REMINDERS AND WIDGETS Reminders for the medications you take, and Home Screen widgets that show today at a glance. PRIVATE BY DESIGN No account and no Vaely server. Your journal is stored on your iPhone, and the App Store privacy label reads "Data Not Collected." Speech is turned into text on your device when on-device recognition is available, and by Apple's speech recognition otherwise; Vaely never stores the audio. Backups are encrypted with a key that stays on your device. PRICING THAT RESPECTS YOU Logging by voice and text is free, with no limit, and three Doctor Reports a year are free. Vaely Pro adds unlimited Doctor Reports, custom tracking and detailed Siri logging for $4.99/month or $39.99/year. On disability or a fixed income? $29.99/year, no verification, no questions. Vaely is a personal wellness journal, not a medical device. It does not diagnose, predict or treat, and it is not a substitute for your clinician. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your device Settings.
