Even with a basic fitbit user-account you can make use of the REST-API of fitbit for free. It would be nice to automatically synchronize the data from a fitbit-account to this health app. This would be possible on-demand (GET/POST) requests, but also by subscription. However for the subscription, you need to set up some web-hook-url. And I don't know nextclouds app-environment as much as I could say if it's possible for one app to provide such a url...
So finally, I am not sure if it's technically easier to fetch health/tracker data manually or by getting notified via subscription. But that would be your design decision. In any way, I would love to have the possibility to collect my tracker-data in my nextcloud-health-app.
