I love (yes, love! 😄) my Renpho body fat smart scale from Amazon. It has an app where it shows many stats like BMI, body fat, muscle mass, protein, body water. It syncs with Noom and Apple Health, as well as other health apps. When my weight ticks up a little, it’s nice to see that it is often due to an increase in muscle. I first got it when I did keto about 4 years ago, so I can compare my progress with Noom as the data and graphs are still in the app. https://www.amazon.com/RENPHO-Bluetooth-Bathroom-Composition-Smartphone/dp/B01N1UX8RW/ref=sr_1_5?crid=3NJF77KEZJOK2&dchild=1&keywords=renpho+scale&qid=1626899128&sprefix=Renpho%2Caps%2C239&sr=8-5
I have this scale
I haven't tested the accuracy of the body fat part, but I have a DEXA scan next month and was planning to compare then.
I got a RENPHO and I love it. The reviews raved and it wasn’t too expensive.

I have this scale and it’s great so far, syncs up to my Apple health and MFP automatically and gives some interesting trend graphs and figures. Also doesn’t break the bank cost wise.
I've been pretty pleased with this one: https://smile.amazon.com/gp/product/B01N1UX8RW
It's not too expensive but it will sync with a phone app via blue tooth to record your weight (and supposedly that app will sync with Fitbit, though I've not tried that).
That said I think your scale is just a dud.
I’ve been using this one since 2018, it works seamlessly with MacroFactor. I think any scale that will sync with Apple or Google’s health apps should work though.
