Cardiomate: Blood Pressure

Blood pressure tracker built for the morning routine. Log systolic, diastolic, and pulse in about 30 seconds. See where you land on the AHA category scale — Normal, Elevated, Stage 1, Stage 2, Crisis.

One reading. Every morning. Clear trends, not single numbers.

Cardiomate is a calm hypertension log. The morning number matters. The pattern matters more. Watch your weekly band tighten — or not — and bring a clean chart to your doctor. Free to use, no ads, no subscription, no account, no data sold.

THE LOOP
1. Log your morning blood pressure.

WHAT YOU GET
• Hero reading card with systolic, diastolic, pulse.
• Dual-line trend chart with systolic + diastolic bands.
• Two-way sync with the Apple Health app. Reading and writing are separate switches — turn on either one, or both. Works with any cuff or watch whose app writes to the Apple Health app, including Withings, OMRON, Beurer and A&D, and it picks up the pulse too, which the Health app stores separately from the pressure pair.
• Measurement details — arm, position, before or after medication.
• Clinical averages — mean arterial pressure, pulse pressure, morning next to evening.
• History list, every entry tagged with its AHA category.
• How to measure — step-by-step guide from the American Heart Association.
• Daily tip. Short. Earned.
• Optional morning + evening reminders.

ABOUT THE NUMBERS
Categories follow the American Heart Association (AHA) guideline ranges. Cardiomate is not a medical device and does not replace a blood pressure monitor or a clinician. Use it to log readings from your cuff and to show your doctor a clearer picture than a single number.

PRIVACY
Your readings stay on your device. They are never uploaded and never sold. No sign-up. Anonymous usage and crash statistics help us fix what breaks — your readings are never part of them.
