It seems that Activity values (like steps) has never been updated.

I put some debug output by console.log and it seems that tickHandler in acrivity.js has been called in every "tick" but get*() functions from activityData has only called at the first time and never been called again. from index.js, only the same value returned any time following line called.

txt.text = data[Object.keys(data)[index]].pretty;

I compared value in index.js like:

console.log("Steps: " + data[Object.keys(data)[index]].pretty + " vs " + today.adjusted.steps);

and it shows different value (today.adjusted.steps updated while previous one never).

It does not check if HRM or activity permissions are granted.

Would be great to see what is a good way to handle permissions not being granted and fail gracefully

Hello! I loved this watch face when I had my ionic and sense watches. Now that I've moved over to pixel watches, I'd love and would pay for a WearOs version of this!!
