This scale from Renpho is the best option if you want a user-friendly smart scale app. The scale uses both Wi-Fi and Bluetooth, which is helpful since it means you can save your data in Wi-Fi mode and sync it up later via Bluetooth. This sleek, black design doesn’t look as fancy as the other high-end scales on the list, but it’s the right size to store in your bedroom or bathroom. The weight capacity is capped at 396 pounds, meaning various people can use it. It’s battery-powered, so if you want a rechargeable scale, this may not be the best choice for you. This scale provides unlimited user profiles and is suitable for weighing infants and adults alike. It’s important to note that, unlike most of the other scales on this list, this one does not have a mode for pregnant people or those with implanted devices. 

Connecting to the Renpho app is easy — all you have to do is find your scale on the Bluetooth device list and follow the directions provided for setting it up. Upon weighing yourself, the only metrics this scale displays is your weight, body fat percentage and BMI. When you open up the app, you’ll see up to 13 body composition measurements displayed in a chart. I liked the interface on this app because even though it’s simple, the design shows all the information in a clear manner. You can click through each measurement and a colorful rubric tells you where you land compared to standard ranges. You can also view your measurement trends in the form of a line graph across a week, month or year. If you’d like to sync your Renpho scale with third party apps, you can connect it to Apple Health, Google Fit, Fitbit App and Samsung Health. I also found the weigh-ins with the Renpho scale to be repeatedly consistent throughout the two week testing period. 

Smart scales can get complicated fast, but Renpho keeps things simple. If you’re new to smart scales or want one that isn’t complicated to follow, you’ll be satisfied with this version.
