Smart scales
Wi-Fi and Bluetooth bathroom scales that log weight and body composition trends, compared on accuracy claims, app ecosystem and subscription cost.
Every scale here estimates body fat and the other composition numbers with a small electrical current through your feet, not a lab test, so treat them as a trend line rather than a diagnosis. The real differences are in sync method, how many people one scale can track, and whether the software behind it wants a subscription.

Common questions
How much should a good smart scale cost?
The ones we track run from about twenty-five dollars to just over two hundred. Budget Bluetooth scales in the twenty-five to thirty-five dollar range track largely the same core metrics as scales costing five to eight times as much; the extra money at the top mostly buys Wi-Fi sync, a wider ecosystem, or a brand's own app polish, not more accurate body fat readings.
Are smart scale body fat readings accurate?
They are estimates from bioelectrical impedance, not a clinical measurement. They are reasonably good at tracking your own trend over weeks if you weigh in consistently, but the single-day number can swing with hydration, food, and time of day, and none of these devices are a substitute for a medical body composition test.
Do I need Wi-Fi or is Bluetooth enough?
Bluetooth is enough for one person who keeps their phone nearby and opens the app after weighing in. Wi-Fi matters more for a household, since it uploads a reading automatically without anyone needing their phone present, which avoids missed or unsynced weigh-ins.
Will a smart scale work with my other fitness apps?
Check before buying rather than assuming. Some scales sync only to their own brand's app, some also push data to Apple Health, Google Fit or Fitbit, and a few are built specifically to slot into a bigger ecosystem, like a fitness watch brand's own app.
