A. 1. Ensure that you are using the scale on a flat, hard surface for accurate readings. 2. Check if the scale is calibrated correctly; refer to the manufacturer's instructions for calibration. 3. Weigh yourself at the same time each day for consistency, preferably in the morning before eating or drinking. 4. If possible, compare the readings with another scale to determine if the issue is with the app or the scale itself.

B. 1. If the readings are consistently inaccurate, consider resetting the scale to factory settings if it has that option. 2. Check for any firmware updates for the scale that may improve accuracy.
