Kuardio is a free iPhone app for the QardioArm blood pressure monitor. Measure with one tap, keep every reading in Apple Health and take a clear report to your doctor. No account, no tracking.
Simple, private and made to feel at home on iPhone.
Start the cuff from your iPhone and watch the pressure live. Take one reading, or let Kuardio average two or three with a rest in between.
Blood pressure and pulse go straight into Apple Health, with arm, position, medication, mood and notes.
If the cuff stops because your arm moved, Kuardio tells you right away and helps you measure again.
Weekly, monthly and yearly trends, morning and evening averages, and a comparison of your arms.
Create a PDF or CSV report for any period, and follow the 7-day home monitoring schedule with a simple checklist.
Reminders with a "Measure now" button, a Lock Screen widget and Siri Shortcuts.
Qardio has closed and its app is gone, but the cuff on your shelf is a good, clinically validated monitor. Kuardio talks to it directly over Bluetooth. No Qardio account, no internet and no server needed.
Works with QardioArm model A100 and QardioArm 2.
Kuardio collects no data. There is no account, no analytics, no advertising and no tracking. Your readings stay in Apple Health on your devices.
Settings and reminders sync through your own private iCloud. Nothing about your health ever leaves Apple Health unless you share a report yourself.
Clean screens, clear numbers and the controls you already know. Dark mode, large text, VoiceOver and haptics are built in from the start.
Every feature in Kuardio is free, for everyone. Nobody should lose a working blood pressure monitor because a company closed.
If Kuardio helps you, an optional VIP Donor subscription keeps it maintained. Donors get a few cosmetic thank-yous, such as alternate app icons and accent colours. Nothing is locked.
Yes. Every feature is free, with no ads and no paywall. Optional donation subscriptions help cover development and the Apple Developer Program; they don't unlock any features.
QardioArm model A100 and QardioArm 2. Kuardio needs an iPhone with iOS 26 or later. Other Qardio devices (QardioBase, QardioCore) aren't supported.
No. Kuardio is an independent app made by a QardioArm owner after Qardio closed. It isn't affiliated with or endorsed by Qardio, Inc. "QardioArm" is used only to say which cuff Kuardio works with.
Kuardio shows all blood pressure readings in Apple Health, from any app. If the Qardio app saved your readings to Apple Health, they appear in Kuardio's history and trends. Data kept only in Qardio's cloud can't be reached any more.
No. There is no account, no server, no analytics and no tracking. Readings are stored in Apple Health; settings sync through your private iCloud. See the privacy policy.
No. Kuardio is a wellness logging app. The measurement is made by your QardioArm, which was cleared by the FDA and CE-marked as a blood pressure monitor. Kuardio starts the cuff, shows and stores what it reports, and does not diagnose, treat or give medical advice. More on the regulatory page.
Not at the moment. Kuardio is built for iPhone and Apple Health.
