We would’ve likely implemented it already, but Google is in the process of killing Google Fit API and replacing it with Health Connect. Health Connect, as of now, is kinda terrible. So we’re waiting for Google to fix their APIs.
I’ve tried my best as indie developer to hurry them :D Last week I was at Gamescom and managed to meet with a director from Google, and asked to connect me with Health Connect team so I can tell them what’s broken and maybe have some insight on when stuff is about to get fixed.
When it comes to Apple, there’s no problem with this. But we want to release wearable support to both platform simultaneously.
