Watch the muscle stay.
Bild Health tracks fat and lean mass, if your scale can report them. A body-composition smart scale syncs to Apple Health, and your fat-mass and lean-mass trends fill in automatically. Four we'd actually buy, at four budgets.

92% of this week's loss is fat. That's the number a plain scale can't show you.
A plain scale shows one number. It can't tell fat from muscle.
On a GLP-1, the whole game is losing fat without giving up muscle. A DEXA scan measures the fat-and-lean split precisely, but you don't get one every week. A body-composition scale is the daily readout in between, and it feeds the one place you already look.
Fat vs. muscle, every morning
A bathroom scale gives one number. A body-composition scale reads what's underneath it, so you see fat leaving and lean mass holding, not just the total.
Syncs to Apple Health
Every scale here writes to Apple Health over Wi-Fi or Bluetooth. Step on, and the numbers are on your phone before you've dried off.
Your Results, filled in
Bild Health reads those readings and charts your fat-mass and lean-mass trends from day one on the medication, no manual logging.
Scales we'd actually buy.

Bild Health earns a small commission on purchases made through the Amazon links, at no extra cost to you. We only recommend gear we'd use. We started on the Body Smart, which was great, and recently upgraded to the BodyFit. The BodyFit link goes to Withings (no commission) until it's listed on Amazon. Specs and prices are from the vendors' own listings, checked September 2026.
The scale is the sensor. Bild Health is the readout.
