Garmins are smart fitness watches, not smart watches.
I have a forerunner 255 and it’s amazing for hiking and running which is what I do most times. I can also take calls and see notifications which is all I need and the battery life is amazing.
But just a curiosity question if you don’t mind. You said that your app is heavily inspired by Infinity which is already open source, so why not just fork that and modify it to work with Lemmy?
That’s just straight up bad IT to do something like that.
