POTSKnow your pattern, not just today's number.
A five-minute stand test you can repeat as often as you like. Watch how your heart rate response changes over time, and bring a doctor-ready report to your next visit.
A closer look at the app.
Why a single reading isn't enough.
Built and maintained by one practicing preventive cardiologist, not a company. The app computes what changed. It never renders a verdict.
A single measurement is a snapshot: how you slept, what you drank, whether you were stressed all move it independently of anything else going on.
The same test, run the same way, more than once, shows what's actually changing and what's just noise.
A doctor-ready report, not a guess you're describing from memory.
No clinic visit needed to start paying attention.
A five-minute protocol on your phone, or continuously on Apple Watch.
Plain-language explanations of the criteria and how to prepare for a doctor visit.
Every test you've ever run, not just the last few.
Share or save a report that covers your whole history.
A gentle nudge to retest every few weeks.
Observational notes on how your readings and symptoms change over time.
