Two taps per reading
Big numbers, ±1 buttons and your last reading pre-filled. Time, arm and position fill themselves. Or just say “128 over 82, pulse 71”.

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.
Calmcuff is a logging and organizing tool, not a medical device. It does not diagnose and never gives medication advice. If you feel chest pain, shortness of breath, weakness or trouble speaking, call 911.
Bring your week of readings, done right.
Free to log, forever. The doctor report is 7 days free.
