Connect Apple Health
One tap, read-only access. Cardiogram works with the heart-rate data your Apple Watch already records — no wearing anything new, no manual logging.
Cardiogram watches your Apple Health heart rate and automatically detects 30+ bpm rises within 5 minutes — time, baseline, and peak logged for you.
Read-only access — your data never leaves your iCloud
Your watch already records the data. Cardiogram turns it into episodes, patterns, and a report your cardiologist can actually use.
A 30+ bpm rise within 5 minutes is flagged the moment it happens — with how long it was sustained, the number that matters for the POTS criterion. Workouts and recovery are excluded automatically, so your morning walk never counts as an episode.
Hydration, salt, sleep, medications and how you feel — connect the dots between your day and your heart.
Weekly summaries, resting heart-rate trends and episode heatmaps — exported as a clean PDF stating the exact criterion used, ready for your next appointment.
No new hardware, no manual logging. See it working in your first day.
