I have a withings and I really like it. Their privacy policy made me feel better about allowing my info on the cloud. You can run it offline (it sends weight via Bluetooth to the app but won’t show 7-day trend an scale screen without wifi). I don’t mind that, so I leave it disconnected. I don’t use a home assistant though so I can’t speak to that part.

I have the withings watch also, so I use the app as my catch all health tracker which works well. it’s nice to have everything together. Can’t speak to any others but I’d recommend withings.

I basically did. I stopped using mobile on July 31 since I was using boost and never looked back.

I wrote a case study on the API thing and spent a ton of time researching the different things going down on reddit and off throughout June and July so I used it on PC for that. Haven’t really been back since.
