  • How are calorie targets calculated?
    Our calorie calculator employs the Mifflin-St. Jeor equation to determine your Total Daily Energy Expenditure (TDEE), which is the total amount of energy, in calories, that your body expends in a day. This includes energy spent on basic bodily functions and any physical activities, such as daily tasks and exercise. Your TDEE varies based on several factors including age, gender, height, weight, genetics, and your level of activity. These elements collectively influence how many calories your body burns each day, enabling us to calculate your personalized calorie targets accurately.

  • Do I need to pair my phone's Bluetooth with the Smart Analyzer to get measurements?
    No, it is not necessary to pair your phone's Bluetooth in the traditional sense. To obtain measurements, simply ensure your phone's Bluetooth is activated. Then, proceed to take your measurement. The app will automatically connect to the Smart Analyzer and display your data. This streamlined process allows for a seamless transfer of information without the need for manual pairing.
  • How can I ensure more accurate measurements?
    For the most precise and consistent readings from your Smart Analyzer, follow these tips: Barefoot Use: Always use the Smart Analyzer barefoot. The device cannot accurately measure body fat percentage through shoes or socks. Dry Feet: Ensure your feet are dry before stepping onto the analyzer to improve conductivity and accuracy. Proper Placement: Position your Smart Analyzer on a hard, flat surface. Soft surfaces, such as carpet or linoleum, can disrupt the accuracy of your readings. Even Weight Distribution: Stand with your weight evenly balanced between both feet to ensure the readings are as accurate as possible. Consistent Timing: Weigh yourself at the same time each day. Weight and body fat percentages naturally fluctuate throughout the day, so consistent timing helps in tracking true trends. Calibration After Moving: If you move or store your Smart Analyzer sideways, it will recalibrate the next time it's used. You may need to weigh yourself up to two times consecutively to allow the analyzer to recalibrate and return to providing accurate measurements. Adhering to these guidelines will help ensure that you get the most accurate readings from your Smart Analyzer.
  • What does it mean when the Analyzer displays "Lo" and doesn't take any measurements?
    The "Lo" message on your Analyzer indicates that the battery level is low, which is why it cannot take any measurements. To resolve this issue, please replace the current batteries with new ones. Once the batteries are replaced with fresh ones, your Analyzer should start working properly again. Ensure you use the recommended battery type for optimal performance.
  • Can pregnant women use the Scale?
    We advise caution for pregnant women when considering the use of this scale. Due to the scale's method of measuring body composition, which includes sending a very low electrical current through the body, it is generally not recommended for pregnant women. This is out of an abundance of caution to ensure both the mother's and the baby's safety. The electrical current, although low, could potentially interfere with the physiological processes of pregnancy. Additionally, individuals with implanted medical devices or metal parts within their body, such as pacemakers, stents, or metallic joint prostheses, should also avoid using this scale. The electrical current can interfere with the functionality of such devices or react with the metal parts, leading to inaccurate readings or posing a health risk. Here are steps to consider if you are pregnant or have metal implants and wish to use the scale: Consult Your Doctor: Before using the scale, it's crucial to consult with your healthcare provider. They can offer personalized advice based on your medical history and current health status. Alternative Methods: For tracking weight during pregnancy, consider using a traditional weight scale without body composition features. These scales do not send electrical currents through the body, making them safe for pregnant women and individuals with metal implants. Understand the Limitations: If given clearance to use the scale, be aware that the body composition measurements (like body fat percentage) might not accurately reflect the unique physiological changes occurring during pregnancy. Safety First: Always prioritize safety and health over tracking body composition metrics, especially during pregnancy or when dealing with specific medical conditions. By following these guidelines and consulting with healthcare professionals, individuals can make informed decisions about using body composition scales safely.
  • Why do I see different readings when I weigh myself?
    Variations in readings from your Smart Scale can occur for several reasons: Calibration: If the scale is not properly calibrated, it may show inconsistent readings. Ensure your scale displays "CAL" (indicating it has calibrated) after being moved or before first use to guarantee accuracy. Surface Placement: The accuracy of your readings can be significantly impacted if the Smart Scale is not placed on a hard, flat surface. Soft or uneven surfaces, such as carpet or linoleum, can cause discrepancies in the measurements. Movement and Storage: Moving the Smart Scale or storing it sideways against a wall can necessitate a recalibration. Always allow the scale to calibrate (look for the "CAL" indicator) after repositioning it before taking a measurement. Consistency in Measurement Timing: Your body weight and composition can fluctuate throughout the day due to various factors, including hydration levels, food intake, and exercise. For the most consistent trend analysis, weigh yourself at the same time each day, preferably under similar conditions (e.g., before breakfast). By addressing these factors, you can ensure more consistent and accurate readings from your Smart Scale, helping you better track your weight and body composition over time.
  • My scale says it's connected, but no data is showing up in the app. Why is that?
