Questions
Does the app measure blood pressure?
No. An iPhone can't measure blood pressure. Measure with your own monitor and log the numbers in the app, or let your monitor's app save them to Apple Health and they'll come in by themselves.
How do readings from my monitor come in automatically?
Turn on writing to Health in your monitor's own app, then connect in Settings > Apple Health in this app. From then on, blood pressure saved to Health shows up in the app by itself.
Why is my level different from what my doctor said?
The app uses the published guideline for your country, which you can change in Settings > Standard. Your doctor sets targets for you personally, so follow your doctor's advice; you can also set the target your doctor gave you in the app.
How do I move my readings to a new iPhone?
They move with your iPhone when you transfer it using iCloud Backup or a computer backup. You can also use Settings > Export and backup > Export backup file, then Restore from backup file on the new iPhone.
My alarm reminder didn't ring
Alarm reminders need iOS 26.1 or later, and the app must be allowed to schedule alarms in Settings > BP Notebook. Without that, reminders come as notifications. Once you've logged that time of day, it stays quiet that day.
How do I cancel a subscription or restore a purchase?
Cancel in Settings > [your name] > Subscriptions. After moving to a new iPhone or reinstalling, tap Restore purchases on the Pro screen.
Is my data uploaded?
No, it stays on your iPhone. See the Privacy Policy.
Still need help?
Write to us and we'll usually reply within a few days. Please include your iPhone model and iOS version; there's no need to send your readings.
