Data exchange with the Apple Health app or Google Health Connect

BloodPressureDB supports importing and exporting Blutdruckdaten and weight to the Health App / Health Connect, which makes it much easier to share data between the two apps. However, this feature is only available on devices that support Apple Health or Google Health Connect.

To import or export Blutdruckdaten from or to the Apple Health App or Health Connect App, please open "Import/Export" in the BloodPressureDB app and choose either "Import data from Health" or "Export data to Health." Before the import or export runs, the data sets are compared and you will see how many items will be read from Apple Health / Google Health Connect or written to the Apple Health app / Health Connect.

Pulse values are only considered together with blood pressure readings. That means a pulse value is only accepted and imported into BloodPressureDB if blood pressure and pulse were recorded at the same time in the Health App / Google Health Connect. Individual pulse readings without an associated blood pressure will be ignored, because using a fitness tracker or an Apple Watch otherwise produces far too many pulse measurements. This would create an enormous number of pulse entries in the list and make it harder to find the blood pressure readings.

Blood glucose values or other parameters cannot yet be imported from Apple Health or Health Connect into the BloodPressureDB app, nor exported from BloodPressureDB to the Apple Health app / Google Health Connect.

Important: The feature needs permission to read data from Health and to write data to Health. This permission is required for the systolic and diastolic blood pressure, and also for the heart rate (pulse).

Note about automatic import and export:
We cannot change values directly in Health. If you change values in BloodPressureDB that were previously exported to Health, those entries will be deleted in Health and then written again. We cannot delete entries in Health that were created by another app. That means if you import values from another app and then change them in BloodPressureDB, both versions may appear in Health. If you delete an entry from BloodPressureDB directly in the Health App von Apple or Health Connect, it will not be deleted in the BloodPressureDB app, because deleted values are not exported.

Note about runtime:

Because Apple Health or Google Health Connect store blood pressure and heart rate separately, we request both values. If you use an Apple Watch or another device to record heart rate, you may have a very large number of records, which increases the time needed for import/export. For automatic import/export we therefore only check the period since the app was last used. On first use, a period of 3 days is checked.
