This is actually it's intended behavior in edge;

I was also confused by it

I'm used to the whoop app where strain builds throughout the day and never goes down.

Yeah I thought it the same. Confused how strain can be 0 when I’ve done activities and workouts ?

Same, I wonder if we can argue for training load (cumulative time in zones) being swapped for strain since that metric (while different) functions the way whoop users are accustomed to in that it goes up and stays up throughout the day. I think that would need to be a new issue though and this one would have to be closed as a duplicate.

I’ve had 2 workouts today and been pretty up and about as well, as strain has just showed 0 all day ?

That's definitely a bug, it shouldn't be showing 0.6 strain on a workout and then a flat line on the chart. Either the workout should be marked as zero strain or the strain chart should register it.

@markpiggott-ctrl I think they have fixed the strain in the v0.11.3 version; my strain is not dropping back down

Nevermind, its still winds down if you rest

This seems to happen for me the day after a workout. Every time log a workout. The next day is a strain if 0.1 or 0.0
