Frequently Asked Questions

Yes. "Blood Pressure Time" can be used completely free with all basic features. There is no account registration or subscription.

The Health app is a general store for many kinds of health data, and it does include a way to log blood pressure — but it's several taps deep (search → Heart → Blood Pressure → Add), and it doesn't automatically average multiple readings taken in one sitting.

Blood Pressure Time is a dedicated app that makes just that entry step easy. Turn on Health integration and your readings are saved to Apple Health automatically too, so you get the best of both: quick daily entry in the app, and long-term storage or sharing with your doctor through Health. See "Apple Health and Blood Pressure Time: How to Divide the Work" on our Useful Tips page for more.

No. Apple Health simply records each reading as entered — it doesn't automatically average multiple readings taken at one sitting.

Blood Pressure Time averages 2–3 entries automatically, matching the method recommended by hypertension guidelines: take a couple of readings and use their average.

No. This app does not have measurement functionality.

This is an app for manually entering and recording values measured with your home blood pressure monitor.

Even those who used to transcribe to paper blood pressure journals can now simply enter data into the app and automatically calculate and record average values.

You can enter up to 3 measurements per session.

When you enter 2 or more measurements, the app automatically calculates and records the average value.

Using average values helps reduce the impact of accidental errors and temporary variations due to external factors (physical condition, tension, etc.).

Deletion is possible, but data modification is not.

From the all records data screen, select the day you want to delete and swipe left to find the delete button.

This feature is currently not supported.

Blood Pressure Time only handles blood pressure and pulse, so a reading never gets lost among dozens of other health metrics competing for the same screen.

Your data stays on your device — it's never used for advertising or handed to third parties. See our Privacy Policy for details.

Your blood pressure and pulse are stored on your device. If you enable iCloud Sync, they are also stored in your personal iCloud (CloudKit). If you enable Health app integration, they are also stored in the Apple Health app.

We never send data to our servers.

Yes (it integrates). When you turn on the Apple Health app integration in Settings, the app saves your blood pressure and pulse to the Apple Health app and can import past data.

You can change permissions anytime in the iOS permission settings, and turn integration off whenever you like.

Note: Pulse in this app is stored as Resting Heart Rate in the Apple Health app.

Strictly speaking, they are different, but in healthy individuals, pulse rate and heart rate match. However, when arrhythmias occur, there can be differences between heart rate and pulse rate.

Pulse Rate: The number of times arteries beat per minute due to blood flow pumped from the heart
Heart Rate: The number of times the heart itself beats per minute

This app records the "pulse" measured by blood pressure monitors, and when the Apple Health app integration is enabled, it is saved as "Resting Heart Rate".

The current version does not have a direct export feature within this app.

However, you can export your blood pressure data as a PDF using the Apple Health app functionality.

For detailed instructions, please see our Useful Tips page.

When you turn on iCloud Sync, your blood pressure and pulse records are automatically shared across iPhones and iPads signed in to the same Apple Account (Apple ID).

It's useful for people who use multiple devices or want to carry over their records when switching to a new iPhone. You can toggle it on or off from "iCloud Sync" in Settings.

When you turn it off, you'll see a dialog asking whether to "Delete from this device" or "Keep on this device."

Choosing "Keep" leaves all records on the device intact. Data stored in iCloud is not deleted.

iCloud Sync: Automatically syncs app data across multiple devices on the same Apple Account. Records are saved inside the app on all your devices.

Health app integration: Saves blood pressure and pulse to the Apple Health app. You can export data as PDF or share it with other health apps. If you enable Health app integration on multiple devices, you can view data from other devices in the Apple Health app even without iCloud Sync — however, records are not saved inside this app on the other device, and sync is not immediate.

You can use either one on its own, or both at the same time.

Yes. If iCloud Sync is turned on, simply sign in to the same Apple Account on your new iPhone and install the app — your data will restore automatically.

Make sure iCloud Sync is turned on before you switch devices.

If iCloud Sync is on when you sign out of your Apple ID or switch to a different Apple ID, a confirmation alert will appear and then the app data will be deleted.

This behavior is specific to this app and differs from typical iCloud apps. Note that data stored in the Apple Health app will not be deleted.

If you plan to change your Apple ID, we recommend turning off iCloud Sync first, or backing up your data using the "Export as JSON" feature in Settings > iCloud Sync.

When you turn it back on, data saved during the period iCloud Sync was off will also be synced to iCloud, and will appear on your other devices as well.

If there is data you do not want sent to other devices, delete it from the app before turning iCloud Sync back on.

No. "Delete all data (Reset)" in the app only removes the app's own data. Data saved in the Apple Health app is not affected.

To delete Health app data as well, please do so directly from within the Health app.

Tap the ⚙️ icon in the upper right of the app → In the settings screen, select "1 time" for Measurement Count. This will save all measurements individually without averaging, even if you enter multiple readings at the same time.

The Japanese Society of Hypertension recommends the following methods and conditions for home blood pressure measurement:

Measurement Environment

1. Quiet room at appropriate temperature
2. Sit in a chair with back support, feet on the floor, without crossing legs
3. Maintain posture and avoid conversation during measurement
4. Avoid smoking, alcohol consumption, and caffeine intake before measurement
5. Environment where cuff position can be maintained at heart level

Measurement Timing

1. Essential timing and conditions
    a) Morning (within 1 hour of waking, after urination, before morning medication, before breakfast, after sitting quietly for 1-2 minutes)
    b) Evening (before bedtime, after sitting quietly for 1-2 minutes)
2. Additional timing
    a) As instructed: evening, before medication, before bathing, before drinking alcohol, during nighttime sleep, etc.
    b) Other times: when experiencing symptoms, weekend afternoons, etc., as appropriate

Number of Measurements and Handling

• Take 2 measurements per session in principle and use the average value
• If only 1 measurement is taken per session, use that value as the blood pressure reading for that session

Our app aggregates and displays blood pressure and pulse separately for "morning" and "evening".

For this purpose, you can preset what time range constitutes morning/evening for yourself.

For example, if you set morning to 5:00-12:00 and evening to 17:00-2:00, measurement values recorded during those time periods will be categorized as "morning" and "evening" on the report screen.

Yes, it's possible. In this case, use the "date boundary time" setting.

If you set the date boundary time to 3:00, even if you set the evening time range end time to 2:00, it will be correctly aggregated as "evening measurements of the same day".

This allows measurements taken late at night or in the early hours to be treated as "evening data".

The "average," "maximum," and "minimum" values on the report screen are categorized based on your morning and evening time range settings.

For example, measurements recorded at 7:00 are aggregated as "morning," and measurements at 20:00 are aggregated as "evening".

Yes. Say "Record in Blood Pressure Time" to Siri and the entry screen opens right away. You can start logging without hunting for the app icon — even while the cuff is still on your arm.

You can also assign it to the Action Button or Back Tap from the Shortcuts app. See Useful Tips for detailed steps.

Currently, only the iOS (iPhone) version is available.

Please try the following:

• Close the app completely and restart it
• Restart your iPhone
