The 6 Best Smart Scales for Weight Tracking (and More)

Woman stepping on scale

Losing weight can be a challenging endeavor, but that doesn’t mean it can’t be done. If you’re beginning your weight loss journey, a good smart scale that can track your progress and sync automatically to your phone or computer will help you stay on track and complete your goals.

What to Look for in a Smart Scale

Before you decide on a scale to track your progress, you should consider what you’re looking for, and what’s the difference between a smart scale and a dumb scale?

  • Compatibility: One of the most important features on a smart scale, is the ability to sync with different apps and upload your weight-tracking data. There are a plethora of different apps that scales can sync to, so you want to make sure the one you buy is compatible with everything you use.
  • Measurements: The scale you buy obviously must be able to measure your body weight, but many scales also offer a variety of other body composition measurements, like body fat, BMI, muscle mass, and even bone density. Sometimes these extra measurements can be less than accurate though, so it’s always important to take everything not directly related to your weight with a grain of salt. If you’re serious about monitoring body fat, you should look into getting fat calipers or a DEXA scan for a more accurate picture of your body.
  • Accuracy and precision: Scales need to be precise AND accurate. To track your progress efficiently and stay on a weight-loss schedule, you need to be sure the weight you’re reading is correct and not off by a half-pound or more.
  • Extra features: Lots of smart scales also offer extra features. There are pregnancy trackers that will keep track of your baby as it grows inside (or outside of) you and many scales also use saved user profiles, so the whole family can track their weight.

Remember: Scales can only be as accurate as you let them be. If you’re having issues with the scale incorrectly reading your weight and fluctuating wildly, it likely just needs to be recalibrated. Just like you would zero or tare out a kitchen scale, these scales need to be retold what their starting weight is every time you move it around.

You should also use the scale on a level surface. Differences in elevation will cause discrepancies in your weight because the force of gravity weighing you down is now being dispersed in the horizontal direction, too, which the scale’s sensors can’t account for.

For best results, weigh yourself at the same time each day—preferably in the morning before breakfast. This way, you’re getting the most accurate look at your true weight every time you weigh in.

The Best for Most People: Eufy P1 Smart Scale

Eufy Smart Scale P1

The Eufy P1 Smart Scale is a solid scale that gives you a larger picture of your health as a whole. It measures your total weight but also estimates your body fat, BMI, bone mass, muscle mass, and ten other health measurements, giving you a general idea of where you are in your health journey.

This scale is very accurate and syncs over Bluetooth to Google Fit, Apple Health, and Fitbit, making it accessible for almost anyone. Setting it up is really easy, too. Just put in the three AAA batteries that come with it, download the EufyLife App (iOS, Andriod) to pair the scale to your phone, and then connect it to your other accounts from there.

The Budget Pick: RENPHO Smart Body Fat Scale

RENPHO Bluetooth Body Fat Scale Smart

We’ve written about the Renpho Smart Body Fat Scale before and still think it’s a great choice if you’re on a budget. This scale measures your weight and tries to estimate your body composition measurements using its four electrodes. This data will all be synced to your phone through Bluetooth.

The Renpho app (iOS, Andriod) was made specifically for these scales to keep track of all your data. It can sync with Samsung, Google, Apple, and Fitbit Health apps, so there should be an option for most people. Also, if you use the scale without your phone near you to sync the data, the Renpho Smart Scale will save it for later until the next time your phone connects to it.

Health Mate also lets you set a goal weight and includes a nutrition tracker that can sync with MyFitnessPal, LoseIt!, and other food-tracking apps.

On top of being precise and accurate at measuring weight, the Withings Body+ will perform a full body composition scan to estimate your body fat, muscle mass, water percent, and bone mass. You can save this data for up to eight users on one account. Withings also offers a cheaper model without the body composition features.

The Withings Body+ automatically detects who’s standing on it by using past data and will sync measurements to the correct user profile as soon as someone steps on it. The scale also includes a Baby Mode for accurate measurements of the smallest members of your family and can track the progress of a pregnancy.

The scale measures only weight and BMI, but upgrading to the Aria 2 will give you more features. It’s not the most robust option on the list, but if you’re dedicated to staying in the Fitbit ecosystem, it’s still a good choice.
