The A&D Medical Premium Wireless scale has a 450-pound weight limit — higher than our picks’. Somewhat annoyingly, though, its app requires you to manually confirm your weight and then enter your height every time you record a reading from the scale — effectively invalidating some degree of automation. The scale is compatible with Google Fit and Apple Health. This model is FSA-eligible with from a physician, and it has a two-year warranty.
With the Fitbit Aria Air, you need to have the Fitbit app open in order to transmit data from the scale, and it’s not compatible with Apple Health.
The Garmin Index and Index S2 are both more expensive than any model we tested. Several customer reviews have highlighted accuracy concerns with both scales.
The GE Smart Scale has an LCD color screen that lists metrics like weight and body fat percentage all at once, but the numbers can be a bit small since they’re stacked on top of each other. Our test readings didn’t have huge fluctuations, but in our experience the batteries seemed to drain more quickly than in other scales. The accompanying app is plain and basic; it tracks weights and other metrics over time, but doesn’t provide the sort of analytical insight most other smart scale other apps do.
During setup, we had difficulty connecting the Greater Goods Premium Bluetooth Smart Scale to its accompanying app, and several online reviews mention similar troubles over time. Then, when we set the scale to read in pounds, it switched over to kilograms. The scale has a clear digital display, connects to a bevy of fitness apps, and has a maximum weight of 400 pounds. But in our weight tests, this scale underperformed compared with our picks.
The LePulse F4 has a large LCD display that, like that of the GE Smart Scale, stacks a bunch of information on one screen, making the information somewhat difficult to read. (We found it overly busy.) Our test readings were fairly accurate, and the app provides helpful analytics. Still, we’ve found our picks offer better overall experiences for the price.
The Omron Body Composition Monitor and Scale BCM500 has the lowest maximum user weight (330 pounds) of all the models we tested. It allows for four user profiles—half of what several other models accommodate. We found its weight readings to be middle-of-the-road, and the app had a simple and basic layout.
The QardioBase X Smart Body Composition Scale was noticeably heavier than our other scales; it’s listed as weighing 6.6 pounds. And that didn’t lead to more-accurate measurements: During our dumbbell weight tests, this scale was, on average, off by 0.4 pound, among the least accurate measurements of any scale in our lineup on those particular tests. We did like that it has Bluetooth and Wi-Fi capabilities and a rechargeable battery that’s advertised as lasting 12 months per charge. The app is pretty basic; it’s easy to read but with no standout features.
On the surface, the Withings Body+ scale is not all that different from the FSA-eligible scale that we like. It is Bluetooth- and Wi-Fi–compatible, and it can be connected to major health apps, such as Apple Health, Google Fit, and Fitbit (as well as to over 100 other apps, according to Withings). It accommodates eight users and has a two-year warranty. But in our weight tests, we found that the Body Smart scale performed slightly better, and it has a higher maximum weight (440 pounds versus 396 pounds for the Body+). Also, the Body+ scale lacks a color screen. It regularly took longer for a weight to register on the Body+, with the reading fluctuating by half a pound (up or down) several times before landing on a number. If you choose to take stock in , the Body Smart scale also has more features, like advanced body composition and basal metabolic rate readings.
If you prefer a more information-rich screen than the offers, the Wyze Scale Ultra is your answer. With a large, color display that shows graphs of weight fluctuations after each reading on the scale itself, the Scale Ultra is a worthwhile upgrade from the Scale X for people who don’t want to open the app as often. Both scales have the same weight maximum (400 pounds) and physical dimensions (just under four pounds and under one foot in length and width), but we much prefer the longer battery life of the Scale X (22 months, the company says, versus the Scale Ultra’s nine).
