Questions

Does Calmcuff take my blood pressure?

No, and no phone can on its own. Use an upper-arm cuff (a validated list is at validatebp.org) and log what it shows. Calmcuff keeps it in order.

My Apple Watch sent a hypertension notification. Now what?

A notification isn't a diagnosis. Apple suggests a week of readings with a cuff, shared with your doctor. Calmcuff guides you through that week and builds the report.

Will I lose my readings if I don't pay?

Never. Logging, your full history and CSV export are free forever.

Does Calmcuff tell me what my numbers mean?

It shows reference ranges based on AHA categories, and that's it. Calmcuff doesn't diagnose and never gives medication advice. Talk to your clinician about your numbers.

Where is my data?

On your iPhone, and in Apple Health if you connect it. It's never sent to us, to analytics or to advertisers.
