Introduction and relative newcomer to QS tracking

Hello all…
Great website here. I recently downloaded the QS iOS app and decided to create a table of certain data items. When viewing the CSV file in Excel, I noticed dates going as far back as 2015. I purchased my iPhone 7 earlier this year. Are these dates from previous iPhone backups?

Thanks so much.

Yes, if your new phone has data on it from your previous phones, then this is likely the source of your HealthKit data. HealthKit was released in 2014, so perhaps the 2015 start date reflects your beginning to use a phone with HealthKit running in 2015.

Makes perfect sense…thank you!
