Why is my body weight not accurate?

Q: Why is my body weight not accurate?

A: If you think you are getting a inaccurate weight measurement, please try below steps to fix the problem inaccurate issues:
1. Place the scale on a hard and flat surface. Softer floors such as carpet can cause inaccuracies.
2. Step on the scale with one foot until the LED screen lights up. Then step off and wait for the LED screen to display “CAL”. When "0.00" is displayed, the scale is calibrated and you could step on it for measurement.
3. During the measurement, try to keep your weight centered directly above and over the scale as much as possible.
4. Try waiting for the scale to auto-shutoff (about 10 seconds) and you should be able to view accurate results via app.

Thus, if you weigh yourself multiple times during the day, you will see some differences. To minimize the fluctuations, weigh yourself the same time each day (such as the morning)

50kgs: ± 0.3kg
100kgs ± 0.4kg
150kgs ± 0.5kg
110lbs: ± 0.66lb
