Digital bathroom scale, 400 lb capacity

When tracking weight alone stops giving you enough context, this digital bathroom scale adds body-composition readings and app-based history in one setup. It measures weight and reports 13 metrics, including BMI, body fat, body water, and BMR, then syncs data to the FITDAYS app when your phone and scale are connected. That makes it easier to spot longer-term changes than relying on a number you jot down occasionally. The tradeoff is that composition readings come from bio-impedance, so this is best approached as a way to follow trends, not as a clinical assessment.

Key specifications

The scale has a listed maximum capacity of 400 lb and uses four sensors and four electrodes to take readings. Along with weight, the 13 body-composition measures include subcutaneous fat, protein, body age, and BMI. The listing does not give dimensions, so whether it fits a particular storage spot cannot be judged without that measurement.

The FITDAYS app is available for iOS and Android. It stores historical data and displays charts across days, weeks, months, or years, giving you a way to look beyond a single weigh-in. The app can also sync with Apple Health, Health Connect, and Samsung Health. That connected history is the main difference from a basic bathroom scale: instead of recording weight manually, you can keep several measurements together on your phone. The scale also has step-on operation and low-power and overload indicators.

Who it’s for

It suits you if you want a simple routine for checking weight and watching app-based trends over time, especially if several people in your household want to use one scale. The listing says it supports 24 users, so separate profiles can help keep personal readings organized. For example, you could weigh in before getting ready, then check the app’s weekly chart later rather than trying to remember whether a day-to-day change is meaningful.

Not the best choice if you only need a straightforward weight reading and have no interest in app tracking, a basic scale would avoid the extra setup. The body-composition figures also shouldn’t be treated as medical measurements. Bio-impedance provides additional estimates, but the listing doesn’t establish how closely those figures match a clinical assessment.

Included in the package

Three AAA batteries are included, so the scale is supplied with batteries for getting started. The FITDAYS app is available as a free download, but phone syncing requires the scale and phone to connect successfully. If you prefer not to use an app, the product’s connected tracking features won’t add much to your routine.

Questions before you buy

Can it track more than weight? Yes. It reports 13 body-composition metrics, including BMI, body fat, body water, and BMR, and can save readings in the app.

Can several people share it? The listing states that the app supports 24 users. It does not describe how profile setup works, so expect to use the app to manage shared tracking.

Which health apps can it sync with? FITDAYS can sync with Apple Health, Health Connect, and Samsung Health, according to the product details. Successful syncing depends on connecting the phone and scale.

Final verdict

This Posture scale makes the most sense for buyers who want more than a weight display and will actually use app charts to follow changes over time. Its 400 lb capacity, included batteries, and support for multiple users cover practical basics, while the 13 metrics add context for fitness tracking. Choose a simpler scale if you want weight only, or a clinical measurement route if you need results for medical decisions. The app connection is central to the value here, so it’s a better fit for someone comfortable keeping health-related tracking on a phone.
