Disappointingly, the Withings Body scale showed wildly different readings when compared with the professional body composition scales at the gym. They also recorded our tester as 3.1 kilograms (kg) / 7 pounds (lbs) heavier than their home Renpho ones. A connected scale that has all the data in the world, somehow doesn’t pull the data in from arguably Garmin’s best customers (the ones who are buying yet another scale from the company). It’s mind-boggling. So in my case, I’ve got piles of data that would show up here – and most importantly from a vanity standpoint, show up with a nice decreasing trendline over the past while. But nope. And it’s easy to say ‘Sure, it’ll fill in over the course of the next 30 days’, and yes, it will. But that’s not the point. Its entire point in life is to be a CONNECTED scale. It fails somehow at this most basic task for the most pro-Garmin customers. Yet, it pulls in the weather data just fine. Stats: Weight, weight trend, BMI, bone mass, skeletal muscle mass, body fat percentage, body water percentage, weight-only option, multiple daily weigh-ins

Resting heart rate and, therefore, basal metabolic rate (BMR) measurements also seem off. Nevertheless, we enjoyed using the Eufy P2 Pro, and considering the low price, it's easy to look past the scale's flaws and appreciate its many useful features. The P2 Pro might not be the best smart scale on the market, but it's worth the money – not to mention, it syncs with third-party apps such as Apple Health, Google Fit and even Fitbit. While I don’t use it myself, a bunch of people seem pretty happy with it. Alternatively, for iPhone users, there’s also the HealthFit app, which can pull the data that Garmin Connect Mobile puts into Apple Health, and from there send it off to 3rd party platforms.

This is usually done via a process called biometric impedance analysis, or BIA. Smart scales utilize BIA by sending a current of electricity from your feet through to your body. The electrical current travels through your fat, muscle, and bone at different speeds due to the different tissue densities, and because the current records the speed at which it travels, it can tell you how much of each you have in your body. The electrical charge is safe for most people, but if you have a pacemaker, medical implant or are pregnant, it’s best to speak to your doctor before you use one. Are smart scales accurate? Now, to run through what’s new on this scale, I’ve got the Index 1 and Index S2 side by side. Both literally and figuratively. I’ve been using them side by side, seeing how they compare for a bit now. Here’s all the differences between them (and yes, these are mostly minor): There was a software update that took several minutes to complete. But once this was done, the scales were ready to use.

This isn't a scale you'll want to be carrying often (it's much heavier than the others in this listing), but its two-layer design with no feet means it can be used on any type of floor. That's a real win if you want to weigh yourself in a carpeted bedroom – electric scales are usually only suitable for hard floors, Press the reset button on the underside of the scale for a few seconds. After a few attempts, you will get the gear icon on the S2 Scale display. Here’s a closer look at the feet and batteries. You don’t need the feet if placed on a hard surface, but the batteries are required if you want the scale to do anything other than act as a paperweight.

Like Withings' other scales (listed below). the Body+ is well designed has a particularly large, bright display that's easy to read when standing up, and a sizeable toughened glass platform that makes it easy to balance. Measurements are consistent, and comparable with those from professional gym scales.

It’ll ask you to confirm the PIN number, to ensure you’re not snooping on your neighbor’s unconfigured scale or something. So first tries to get it to connect to Connect, and they failed. I was getting indications that it needed an important update, and wouldn’t (apparently) connect without it. The saving of multiple data points per day certainly isn’t new in the Garmin Index scale world, it’s been doing that for quite a while with the older scale, but it wouldn’t show the change in weight.

The WiFi connectivity is a perk

We love how it syncs with all the main health apps (from Apple Health and Fitbit to MyFitnessPal) so it’s really simple to access your data in one place. You can measure 13 different body metrics and the app gives further insight into how these relate to the average person, in terms of being healthy or unhealthy.

Note: Above, I was purposefully taking a bunch of weigh-ins slightly differently to show multiple weigh-ins on a single screenshot) Ultimately, the Garmin Index S2 works well, with accurate results in testing, but it slightly under-delivers for the high price.

Do I need a smart scale that measures body fat?

The app will ask you if you’d like to invite any other users to the scale. You can invite up to 15 people (thus presumably making 16 people in total). While it’s unlikely your Brady Bunch is that big in your house, this is more for team scenarios where multiple athletes are weighing in. Garmin has just announced the new Index S2 smart WiFi scale, building slightly upon the previous first-generation Index WiFi scale released nearly 5 years ago. This new model switches to a color display that’ll show weight trending information, helping to visualize the normal day to day fluctuations. It also adds a handful of tweaks like being able to customize the data widgets on-screen, showing difference to previous weigh-in, as well as increasing the sensitivity of some of the sensors driving the algorithms related to body fat & impedance-based measurements. Overall it’s a minor upgrade.
