The default tab has a line graph depicting your weight over a period of time along with percentage changes in your BMI, body fat and body water. The app is not my favorite design, because the measurements could be displayed in a more user-friendly way. The app tells you if each metric is within a low, standard or high range, but there isn't much explanation beyond that. As with many other smart scales, you can set up a goal weight for yourself and connect to integrated programs such as Apple Health, MyFitnessPal, Samsung Health and Google Fit. Make sure your Bluetooth is on so the scale properly connects to the app. On the app you get an extra 12 body composition readings: body mass index, body fat percentage, subcutaneous fat, visceral fat, fat-free body weight, body water percentage, skeletal muscle, muscle mass, protein, bone mass, basal metabolic rate and metabolic age. The Qardio app connects to the scale and has simple steps to sync up and personalize your experience. So keep in mind that you may have to weigh yourself more than once to get the most accurate reading.

The only time I noticed it was off from time to time was during the first measurement. Usually readings on the Qardio were accurate during the daily weigh-ins. It's one of the few scales that functions well on any surface - even a carpet - which is always a plus. It also has modes for pregnant people and people with implanted devices, avoiding potential harm or interference by turning off the electrical currents used by most smart scales to read metrics aside from weight. It's suitable for up to eight users and has several modes to pick from, including one for athletes and one called 'out of sight' if you don't want the weight to appear on the scale. It has a weight capacity of up to 396 pounds. It's compatible with Wi-Fi and Bluetooth, can be recharged with USB-C and it can read units in kilograms, stone and pounds. Admittedly it's large and heavy (weighing about 7 pounds), but the sleek design makes it an appealing piece of technology, even if it's just a scale. QardioBase X is our top pick because of its customizable functions and ability to be used on different surfaces.
