Readings appear twice

The app tries not to store a reading twice. A reading that comes from Health Connect is recognised by its Health Connect record, or by exactly the same date and time. A file import skips readings with the same date and time. When a copy still appears, one of the cases below is the reason. Health Connect is available in the Google Play version of the app.

To remove a copy, delete it in History, as described in Change or delete a reading. Deleting is not synced: a copy that is also in Health Connect stays there until you delete it there too, with Sync data with Health Connect and then View records.

You typed in a reading that your monitor's app also saved

The monitor's app saves the reading with the exact time of the measurement. The reading you type in has the time you set, which is usually a minute or more apart. The app cannot tell that they are the same reading.

If your monitor's app saves readings in Health Connect, let them arrive by themselves and do not type them in as well. Delete the copy you typed in.

You changed the date or time of a synced reading

The app writes the changed reading to Health Connect as a new record. Health Connect keeps the old record with the old time, so other apps see both. If you switch sync off and on again later, the old record also comes back into this app.

Delete the record with the old time in Health Connect, with View records.

You imported a CSV file on a phone where Health Connect already had the readings

A CSV file keeps the time of each reading to the second, while Health Connect keeps the exact moment. So the app does not match them: the readings from Health Connect appear next to the imported ones, and the imported ones are written to Health Connect again.

To move readings to a phone that uses Health Connect sync, use the Google Drive backup instead: it keeps the exact times. If it has already happened, delete one copy of each reading, in the app and in Health Connect.

You imported a file while a filter was on

When you import a file and tap No, the app skips the readings it already has, but it compares the file only with the readings the current filter shows. Readings hidden by the filter are imported a second time.

Before importing, open Filters in History and tap Clear. If copies are already there and the file has all your readings, you can start again: import the same file and tap Yes. The app then deletes all readings of the profile first and imports the file. Readings that are not in the file are lost.

Still seeing copies

Write to the developer. Say which app your monitor uses, whether Health Connect sync is on, and attach a screenshot of the two readings in History.
