How do I sync my WW Bluetooth Body Analysis Scale to the WW app?

First, ensure that Bluetooth is enabled in your mobile device settings. Then unbox your scale and follow these steps: Flip the scale over and remove the tape covering the battery. Place the scale on the floor. Scan the QR code on the scale’s box using your smartphone’s camera. Click the link, which will redirect you to the WeightWatchers sign-in page. Sign in and select OK/Allow when the pop-up asks if you want to allow WeightWatchers to use your mobile’s Bluetooth. Once the device has been connected, you will be prompted to tap the scale to wake it up. Then wait for 0.0 to appear on the scale. Step on the scale and within a few seconds, your weight and body measurements will be transmitted to the WW app. Stay on the scale until the Confirm & Track button pops up. Tap to track. Alternatively, once you’ve removed the tape covering the battery, you can open your WW app, tap the Menu (the three horizontal lines on the upper left), then navigate to Settings. Tap Connected Devices and select your scale. Continue to follow the prompts to connect your scale.

What is the most accurate way to measure my body weight with a WW Bluetooth Body Analysis Scale?

The scale is incredibly precise, so there’s no need to stress over your technique. That said, we’ve got a few basic pointers: Place the scale on a hard surface since soft flooring like carpet can be uneven. Wear minimal or no clothing and no shoes. Step on the center of the scale. Stand still and don’t lean on or touch anything while your weight is being measured.

How do I most accurately measure my body fat, water content, muscle mass, and bone mass with the WW Bluetooth Body Analysis Scale?

Step onto the scale barefoot. If you’re wearing shoes, the scale won’t be able to provide an accurate measurement. Align your bare feet with the metal strips (electrodes) on either side of the scale. If you get an error reading, check to make sure your feet are fully aligned with the metal strips. If they are and you are still getting an error reading, try rubbing a little lotion on the soles of your feet, as dry skin can interfere with the measurement.

When using my WW Bluetooth Body Analysis Scale, I keep getting a body metric error reading message. How can I fix this?

We’re sorry to hear that. There are three possible reasons you may be getting that error message: You are wearing shoes or socks. Shoes and socks prevent the scale from properly functioning. Make sure you step onto the scale with your bare feet. Your feet are not covering the sensors. There are sensors on the scale—metal strips on either side of the device—that calculate your body measurement data. Make sure both your bare feet are covering them. You are not standing on scale long enough. Since the scale calculates several body measurements, it may take longer to get a reading than your typical body-weight scale. Make sure you stand on the scale until you see your weight confirmation pop-up in the WeightWatchers app

What are the benefits of weighing myself more than once a week?

There are five main benefits: More information. The more days you track your weight, the more data you collect to help you understand the typical patterns of your weight-loss progress. Better understanding of weight changes. Tracking your weight more often can help you recognize the difference between normal (but insignificant), day-to-day weight fluctuations versus meaningful weight changes over time. Reduced pressure on any day or number. Tracking your weight more often can make the experience feel less daunting, and make the scale feel less intimidating—because it starts to become a normal part of your regular routine. Minimized mental effort. Tracking your weight is a simple, specific, repeatable behavior—and that means it is ripe for habit development. With enough repetition, stepping on the scale in the morning right after you wake up can become a habitual part of your morning routine that you won't need to think about. More weight-loss or maintenance success. The research is clear that people who track their weight more often lose more weight. More frequent weight tracking is also associated with less weight regain for people who are maintaining weight loss. 1-4 (1) Burke LE, Wang J, Sevick MA.

How do I interpret or use the data from weighing myself daily?

Focus on the big picture When your goal is to lose or maintain weight, it’s best to review and learn from the trends you see over time rather than draw conclusions from what the scale says on any one day. That’s because body weight can fluctuate from hour to hour and from day to day due to a variety of factors, such as: How much sodium (salt) you have eaten - How large or small your most recent meals were - How hydrated you are — which can be influenced by exercise, illness, and fluid intake - Hormone levels and menstrual cycles Given how many factors can impact your weight during the day, there is no “normal” range of weight fluctuation; it can vary significantly by several pounds or more. This is one reason it’s important to weigh yourself only once per day and at the same time and in the same situation. We recommend doing it right after you wake up, after using the bathroom, without clothes on, and before having anything to eat or drink. Remember slow and steady is sustainable A healthy rate of weight loss is 1 to 2 pounds a week. But this is an average; it’s important to know that weight loss does not occur in a straight line. Small weight gains and losses, as well as plateaus, are common along the way as your body adjusts to your new eating, activity, and other self-care habits. Also know that different scales often give slightly different results. For example, the scale at your doctor’s office or WeightWatchers Workshop may show one weight, while your scale at home shows another. If you use different scales in different circumstances, we recommend tracking your weight trends based on one scale only.

We use industry-standard security practices to protect the data we receive from your WW Bluetooth Body Analysis Scale. We use that data to complete your weight dashboard and help you gain a more complete picture of your health and your weight-loss journey.

No, you do not need a smart device to weigh yourself or see your weight or any other data measurements displayed on the scale. However, if you want the scale to transfer your data to the WW app and track your weight automatically, you do need one. This is because a Bluetooth connection—available only via smart devices—is required to sync the device with the app.

No, you do not need Wi-Fi to use the scale nor to have it transmit data to the WW app and track your weight automatically. The scale uses a Bluetooth connection to communicate with your smart device, not Wi-Fi.

Using your scale

If you have already connected your scale to the WW app, make sure your phone is located near your scale and that the WW app is open. Tap on the center of the scale to wake it from sleep, then step on the scale and your weight should automatically display in a pop-up. Tap Confirm & Track to record your weight.

If you have not synced your scale to the WW app, do so first. After unboxing your scale and removing the tape on the back, open your WW app, tap Menu (the three horizontal lines on the upper left of the home screen), Settings, then Connected Devices. Tap the WW scale icon and follow the prompts to connect your scale.

The scale is incredibly precise, so there’s no need to stress over your technique. That said, we’ve got a few basic pointers:

Place the scale on a hard surface since soft flooring like carpet can be uneven.
Wear minimal or no clothing and no shoes.
Step on the center of the scale.
Stand still and don’t lean on or touch anything while your weight is being measured.

Step onto the scale barefoot. If you’re wearing shoes, the scale won’t be able to provide an accurate measurement.
Align your bare feet with the metal strips (electrodes) on either side of the scale.
If you get an error reading, check to make sure your feet are fully aligned with the metal strips. If they are and you are still getting an error reading, try rubbing a little lotion on the soles of your feet, as dry skin can interfere with the measurement.

Yes, all WeightWatchers members can use the same scale to sync their weight and body measurements. To ensure correct tracking, make sure the scale is connected to each member’s WW app, that each member has their own smart device near the scale while weighing themselves, and that each one taps Confirm & Track on the weight confirmation pop-up.

That’s totally up to you, but you may want to consider upgrading to the WW Bluetooth Body Analysis Scale because it syncs with the WW app to automatically track your weight. That can make tracking your weight feel more seamless, which can help it become a habit. That’s important since frequently and consistently weighing yourself can help you lose more weight and keep it off.^1-3 Whether you stay with the scale you currently have or upgrade, make sure you stick with that one scale each time you weigh yourself; different models may give slightly different results.

The WW Body Analysis scale is rated for those who weigh up to 400 pounds. We also do not recommend it for those who have an electrical implant, such as a pacemaker, or if you are pregnant. If you are above the maximum weight, or if you have an implanted electrical device or are pregnant, please reach out to customer support using 24/7 Live Coaching in the WW app (find it in the Menu—the three horizontal lines on the upper left) and we will gladly send an alternate model that will work for you.

We are working toward populating the graphs with your body analysis metrics. You can expect to see the graphs with your metrics before the end of February.

Troubleshooting

We’re sorry to hear that. Please reach out using 24/7 Live Coaching in the WW app (find it in the Menu—the three horizontal lines on the upper left) and we’ll happily work to help resolve any issues.

Step off the scale and check your WW app. You should see an error pop-up there too. Tap X to dismiss it, and wait a few seconds before you tap the scale to wake it up. Once the display reads 0.0, the scale is ready for you to try again.

We’re sorry to hear that. There are three possible reasons you may be getting that error message:

You are wearing shoes or socks. Shoes and socks prevent the scale from properly functioning. Make sure you step onto the scale with your bare feet.
Your feet are not covering the sensors. There are sensors on the scale—metal strips on either side of the device—that calculate your body measurement data. Make sure both your bare feet are covering them.

Weight-tracking 101

We recommend weighing yourself somewhere between once a week and once a day, as research shows that weighing yourself in this range has significant benefits on a weight-loss and maintenance journey. (In other words, more frequent weight tracking leads to more weight-loss success.^1-4)

That said, there is no exact “right” frequency; as with everything on your WeightWatchers journey, it’s important to do what works for you so you can keep it up. If you aren’t sure how often to step on the scale, think about what seems doable for you. Three days a week? Two days? One day? Start there to establish a routine over the course of a few weeks. Then try to add one more day per week. After you’ve tried that for a while, decide how to move forward: Stay with that frequency, add another day, or cut back a day.

Do not weigh yourself more than once a day. Any changes you see in your weight throughout the day are due to variables that aren’t that meaningful for long-term weight loss or maintenance.

No matter how many days a week you decide to track your weight, approach it with consistency: Do it on the same day(s), at the same time, and in the same situation every time—such as right after your more shower.

One reason is that it helps cultivate awareness. When you step on the scale, you’re present and can see the impact your behavior changes around food, activity, sleep, and mindset are having on your progress. It’s a moment to reflect on what’s working and what’s not.

Remember, the weight-loss journey can be full of ups, downs, and plateaus. This helps put weight into perspective: Even if the number isn't what you want, you stay focused on the journey ahead. That’s why we recommend that members who want to lose or maintain weight should develop a habit to weigh themselves regularly.

There are five main benefits:

More information. The more days you track your weight, the more data you collect to help you understand the typical patterns of your weight-loss progress.
Better understanding of weight changes. Tracking your weight more often can help you recognize the difference between normal (but insignificant), day-to-day weight fluctuations versus meaningful weight changes over time.

We recommend doing it right after you wake up, after using the bathroom, without clothes on, and before having anything to eat or drink.
Remember slow and steady is sustainable
A healthy rate of weight loss is 1 to 2 pounds a week. But this is an average; it’s important to know that weight loss does not occur in a straight line. Small weight gains and losses, as well as plateaus, are common along the way as your body adjusts to your new eating, activity, and other self-care habits.

Also know that different scales often give slightly different results. For example, the scale at your doctor’s office or WeightWatchers Workshop may show one weight, while your scale at home shows another. If you use different scales in different circumstances, we recommend tracking your weight trends based on one scale only.

Weight changes from day to day are generally not meaningful—whether the number is going up or down. Your body is a complex machine that is constantly taking in and burning energy in the form of food and liquids. Factors such as how much salt you ate today compared to yesterday, how hydrated you are today compared to yesterday, and how productive your digestive system has been today compared to yesterday can all influence your weight.

Resist the urge to compare today’s weight to yesterday’s or tomorrow’s weight. Zeroing in on minor and insignificant changes like these can actually distract you from the bigger picture of what’s important—your weight trends over time and the behavior changes you’re making.

Weight changes from day to day are generally not an accurate measure of your progress—whether the number is going up or down. Weight changes from week to week are a more meaningful measure. If you find that your weight is trending upward over the course of a couple of weeks, it’s a good time to reflect on your eating, activity, and food-tracking patterns, and to determine what changes have happened since your weight was last on a downward trajectory. Doing this can help you make a plan for how to move forward on your journey.
