Do iPhone and Apple Watch steps sync at any time or in any app?

Hello.

I've been bothered by this for a while and I see others have posted similar question is, but could find no solution and some of the links posted to help are broken.

On my watch I have my watch face with 'Steps & Distance' os one of the Complications. I am trying to keep track of my steps for health reasons but notice that rarely does my watch match the health app. I understand they may work slightly differently (usually no GPS for Phone), but I I thought at some point the two numbers would sync. Does anyone know if this is supposed to occur? My phone is on my person about 95% of the time I am active except in the evening when if may rest on my chair side table.

For example, last night at 22:01 my watch registered 13,124 steps. My iPhone registered 11,264. This AM the watch of course has gone back done to zero, while my health app records 11,315 steps for the previous day. Eighteen hundred steps is a big discrepancy.

Anybody have any new insight? (iOS 14.5.1)

Thanks!
