What Is A Smart Scale?

If you’re not sure what a smart scale is to begin with, that’s ok. A smart scale, also known as a wifi scale, is simply a type of bathroom scale that can connect to an app for tracking data.

These scales communicate through the internet, that’s how the name “wifi scale” came about.

The type of data these scales can track varies a little from model to model. As a scale, their first function is to measure our body weight of course. All of these devices have that in common.

And even if tracking your weight is your only goal, a smart scale might still be a wise choice because it will save your weights and track them over time for you. If you use a smart phone or pad, this makes it really easy to monitor your weight loss (or gain).

Most smart scales will also calculate your body fat percentage. This is why most folks are interested in getting smart scales. Body fat percentage is a key calculation for determining overall fitness.

It basically tells you how much of your overall weight is made up of fatty tissue. It’s calculated by dividing your fat weight by your total body weight.

For example, if I weighted 100 lb, and I had 20 lb of body fat, my body fat percentage would be 20% (20/100).

But how does a scale determine how much of our body is made up of fat? Good question. It uses something called bioelectrical impedance analysis (BIA). It basically means the smart scale sends a mild electrical charge through your body through the electrodes you are standing on.

Based on how fast the current travels through your body, the smart scale can calculate how much of your body is made up of fat, muscle, and bone. Each of these body tissues conducts electricity differently and the scale is smart enough to calculate your composition.

Just keep in mind these calculations are estimates and things like hydration level, eating, and exercising and skew the results. For more info, check out this article on how smart scales work.

Smart scales can also calculate information such as:

  • BMI
  • Muscle mass
  • Bone mass
  • Water Percentage

How To Pick A Smart Scale

I mentioned at the beginning that there are a ton of smart scales on the market these days. Deciding which one will be best for you can be a little tricky, but I think you should concentrate on 3 factors: metrics, compatible apps, and accuracy.


You really need to consider which metrics you are most interested in tracking before you decide on a smart scale. This is because you need to make sure you find one that tracks everything you are interested in.

Most people are interested in weight, BMI, and body fat percentage. But if you are a competitive athlete or just love tracking data, you may want a scale with more sophisticated tracking abilities.

It’s pretty amazing what some of these scales can calculate. A lot of these scales will measure between 12-16 different metrics. You’ll see what I mean down below.

If you are really into stats, you might want to find a scale that measures a ton of stuff. In a lot of cases, it doesn’t really affect the price either.

Compatible Apps

This is another important thing to consider. We need to make sure our smart scale is compatible with our fitness app of choice. Some scales are compatible with multiple apps while others are limited to 1 or 2.

Most of the apps are free, so you could always download the app a prospective scale uses and play with it to see how usable it is. If you are already using an app you like, look for a smart scale that is compatible.


Obviously we want our scale to give us readings that are as accurate as possible. I don’t think anyone would purposefully buy an inaccurate scale (but you never know). Unfortunately, no smart scale ever admits that it isn’t very accurate.

I guess that wouldn’t make for very smart marketing. So, the best way to get an idea of how reliable the scale is before buying is to read user reviews.

Most scales should be pretty reliable with assessing body weight these days, but not all are. Keep in mind the body fat percentage and other more advanced metrics are estimates.

The key is trying to find a scale that is reliable with it’s estimates (that is, you shouldn’t see a 10% change in body fat over 24 hrs).

Other Factors To Consider

Metrics, compatible apps, and accuracy are important factors to consider when comparing smart scales. Other factors to consider include:

  • Price
  • Weight capacity
  • Platform size
  • Screen size
  • Warranty

Now that we know what to look for, lets take a look at the best smart scales currently available on the market.
