> I have a Renpho scale, the way it works for me is that when I step on the scale it turns it on and connects to my device via bluetooth which wakes the app. The weight is captured and synced in the background to both the Renpho cloud service as well as the local Health Connect.

I bought a Wifi scale specifically so I don't have to have my phone with bluetooth on, nearby. Does the BT-connection open the app itself, or just initiate a sync in a background service? I was under the impression that it is impossible to access Google Health Connect in the background – I get access-errors in my log when I start my own app from the IDE while the screen is off.

> [...] they get a lot of write storage to health connect for free from the API

Is this really an issue that is solved by using Google Health Connect?

You are right, I edited my original post accordingly.

Our has that option, but as multiple people in the house used the scale, having a phone on hand (which we do anyway) streamlines the process versus having to identify the user weighing.. user preference really.

Background service as best as I can tell. I rarely, if ever, open the app in foreground and the weight is captured.
