Bluetooth scales that work

Liftsmith talks to scales that share their reading the standard Bluetooth way: the Weight Scale service, and the Body Composition service for body fat. Lots of scales use a closed protocol that only their maker's app understands instead, and those never show up in the list when you tap the button.

It works in the Android and iPhone apps, and in the web app in Chrome on a computer or Android phone. Close the scale's own app first, because a scale connects to one app at a time.

These scales send their reading over the standard weight service as soon as you step on, with nothing to set up on the scale. We haven't tried each one ourselves yet, so if yours gives you trouble, tell us.

These scales use the standard services too, but they only send a reading once an app has registered you as one of the scale's users. Liftsmith doesn't do that step yet, so for now use the scale's own app and the health store, below.

Most smart scales' own apps can save your weigh-ins to Health Connect on Android or Apple Health on iPhone, and Liftsmith reads weight and body fat from there for free, no lab needed. That includes:

• Renpho (most models)
• Eufy
• Xiaomi
• Wyze
• Garmin
• Fitbit
• Hume Health (Body Pod)
• Withings

To set it up:

1. In the scale's own app, turn on syncing to Health Connect or Apple Health, and allow weight and body fat.
2. In Liftsmith, open Settings › Connected apps › Health Connect (or Apple Health) and allow weight and body fat there too.
3. Weigh in as usual. Liftsmith picks up the reading when it opens, or tap Sync now on the same screen.

Liftsmith keeps one reading a day, so syncing again never adds a duplicate. More in help and questions.

Try it: if it appears when you tap Weigh in on my scale, it speaks the standard. Either way, let us know the brand and model and whether it worked, and we'll add it here.
