Hey thanks for the feedback. The secret? I'm not sure? You had issues with the speed or getting the data and updating the view?

What I did is adding a loading indicator and fetching data onChange, so if I change e.g. bow heart rates are calculated it starts to fetch instantly after the change not only on the view with the bars.

And I'm currently just fetching 30 days. I think this will be interesting if I try to extend it.

Onboarding flow, Home screen widget is on my list. Thanks.

The filtering would also be interesting. Haven't though about hat because I usually myself do always the same workouts

My speed issue was in getting the data (although I think it is fixed now).

The other big performance problem I've had is the simulator hanging when I try to use Swift Charts.

My primary interest was in monitoring my total zone 2 time for cardio workouts where I spend at least 30 consecutive minutes in zone 2. However I've reduced the scope for now while I get the minimum viable app up and running.
