I use Google Fit to track my health data extensively since the end of 2023. In the meantime, Google released Health Connect, which is a platform to store health data from different providers instead of them using the Google Fit API. In 2024, I got a new Phone (P9P), but my historical Google Fit data is not showing up on my new phone’s Google Fit app. Now I found a workaround.

The workaround is to install Google Fit in a work profile. I use Shelter to manage my work profile. I installed Google Fit in the work profile and then set up my Google account and can see my historical data. I think this has to do with Health Connect. Somehow, Google Fit is not able to write historical data to Health Connect, but the data is in the cloud storage dedicated for Google Fit. The work profile does not have access to Health Connect, so Google Fit fetches the data from the original source, but the new data is also there. When I look at the data in Health Connect, I can see that the historical data is not there. It’s not optimal, because now I have two instances of Google Fit and had to sign in to my Google account on the work profile. But at least I can see my historical data again.

The root cause of the problem is that Google Fit is not able to write historical data to Health Connect. If anyone has a solution to this, please let me know.

Also, I think Google Fit does a bad job at displaying time series data because you can only select to view weekly, monthly, three-monthly, or yearly data, which is paginated according to the selected time period. I would like to view the data in a continuous time series together with a regression line and markings for significant events.
