Very regularly zeplife will fail to sync properly with health app on ios. To handle this I have used 2 options
Use AmazeTools for syn
download the data via export and import it to health
a. Find option under settings -> user rights -> export data
b. export data for the timeframe you want
c. download the zip file and open it with password displayed on screen
d. there will be a folder HEARTRATE_AUTO you need to go in and change format of the csv file
I found this to be helpful
sed 's/\(.\{10\}\),/\1 /' HEARTRATE_AUTO_numbers.csv > edited_date_heartrate.csv
This i will then share with iphone and use CSVImport to import the data in health app.
