health integration by michaelthatsit · Pull Request #54 · coredevices/mobileapp
this is pretty early. all it does is pull the health data from the watch, and push the averages to it.
I'm thinking it's probably best to add this and do any UI changes in a separate PR: In...

btw this is a TON of engineering work. Probably would have taken a lot of human time to get working:
- github.com/coredevices/... is back on qemu 2.5, first step was porting all drivers to qemu 10
- then it had to get STM32 running in Emscripten's TCI (Tiny Code Interpreter) which never been done

You'll (soon) be able to purchase an Index 01 sizing kit as well.

If you 3D printed an Index 01 sizer more than 3 weeks ago - you will need to reprint the ring sizer.
Long story short - the ‘individual ring’ STLs were dimensionally accurate in software to the exact dimensions of Index 01 but would shrink when printed on FDM. so ....
