Steps count incorrect on Apple 9 watch

My step count on my watch(Facer) is not the same as my activity step count.

Facer data updates every 15 mins or so. It may recalculate every 1/4 hour.

It’s still incorrect.
Steps are out by 20 steps
The data is not pulling through correctly and I’ve only had this app for 2 days
Will this fixed ?
I have refreshed for an hour

Have you allowed all permissions and have all the right kits for it? Some say they require the Health kit etc
