I’m new to the Inspire 3 Fitbit. My device tells me that I swam this morning but in fact I was tidying out drawers. Can anyone explain?

if it’s wrong on this the. How do I trust it in other data?

Hello @Suesimms50 and welcome to the Community.  All Fitbits use an accelerometer to analyze motion patterns.  Fitbit's auto-recognition feature looks for motion patterns consistent with several types of activity.  What I like to say is, "The accelerometer sees what it sees."  Other uses posted that they got a swim exercise for folding laundry.  Just delete that exercise.
