Eufy Smart Scale P1 vs C1 (2022): Which Smart Scale Has The Edge?

We’ve reviewed many smart scales, but few sell for under $50. Fortunately, Eufy, also known for its budget robot vacuums, is keen on making these health companions more accessible. The Eufy Smart Scale P1 retails for around $45 and tracks 14 body measurements. On the other hand, the $30 Eufy Smart Scale C1 measures 12 metrics.

But are two measurements more worth getting the P1 over the C1? How else are these body composition scales different from each other? Below, we weigh the pros and cons of the two to help you decide.

While both scales feature a tempered glass surface over their body, the P1 adds an ITO coating and hides its contacts from view.

The price difference between the Eufy Smart Scale P1 and C1 isn’t just limited to what they can measure. It also takes into consideration design. Although both Eufy scales are the same shape and size, the P1’s top surface features an indium tin oxide (ITO) layer. It’s an additional level that goes on top of the tempered glass material.

While the name of the technology is fancy, ITO is simply a coating used on non-conductive surfaces. It’s known for its electrical conductivity but is also favored for its moisture resistance. Plus, it can be used as a thin film. In theory, this should make the P1 a more precise scale than the C1.

The C1 lacks this extra ITO layer. Instead, you step right on a tempered glass surface. Below the scale, you get the same G-shaped sensors as the P1. However, the contacts are visible. It’s not the most minimalist approach to design, but the points double as a guide on where to place your feet.

Compared to other smart scales, Eufy’s P1 and C1 are small. This makes them harder to use, especially if you have poor balance. To combat this problem, Eufy adds non-slip, rubberized feet to the scales. The rounded corners also safeguard you from bumps. As for the display, the Smart Scale P1 and C1’s are bright and easy to read. Both devices are also water-resistant.


The Eufy Smart Scale P1 tracks two more body composition metrics than the Smart Scale C1.

Here’s a look at the metrics tracked by the Eufy Smart Scale P1 (left) and C1 (right)

The Eufy Smart Scale P1 and C1 use bioelectrical impedance to generate their body composition readings. As for the unit of measurement, they only offer either pounds or kilograms. If you prefer stones, you’re better off with the Garmin Index S2 or Withings Body+ instead.

Eufy boasts that the P1 tracks 14 metrics, up from the 12 on the C1. Metrics common to the two include weight, water, and body fat percentage, among others. Meanwhile, two metrics exclusive to the Smart Scale P1 are body age and protein levels. While these sound interesting, they’re derived from a few core measurements as the other metrics.

What’s important is that both the P1 and C1 monitor your weight, fat, muscle mass, and bone mass percentages. These are the best indicators of your overall health and are the metrics you should care about.

Despite all the data, however, only bodyweight is shown on the scales’ display. For the additional metrics, you’ll need to view them on the EufyLife app.

It’s reassuring that both the P1 and C1 deliver accurate and consistent results for most people. We say for most people, since non-athletes with higher muscle mass may find the measurements from bioelectrical impedance skewed. In this case, a scale with athlete mode may be better.

Mobile App and Compatibility

Eufy’s smart scales work with the EufyLife app that enjoys integrations with Apple Health, Google Fit, and Fitbit.

Since the body composition metrics are viewable only in-app, Eufy has taken the time to make the platform as intuitive as possible. This companion app, called EufyLife, is different from EufyHome. But if you already have an account for the latter, you can use the same login details for EufyLife.

Overall, the app is well-designed and easy to use. Like the Smart Scale P1 and C1’s screens, the EufyLife uses large numbers that are easy to read for all age groups. Bodyweight is front and center among all these metrics and is displayed in your preferred unit. You can also set a bodyweight goal that’s editable anytime.

Losing weight is a matter of motivation, too. And what better motivation than seeing your progress? On the EufyLife app, you can view your weigh-in history and trends.

Aside from actual result metrics, the app also displays the weight of each tissue type. Once you click on these measurements, your readings are positioned on a scale, allowing you to compare your stats to a standard healthy rating. EufyLife also provides information on how a particular metric can impact your health.

If you don’t want to use EufyLife, you can sync your data with other health apps. Both the Smart Scale P1 and C1 integrate with Apple Health, Google Fit, and Fitbit.

Setup and Battery

Setting up the EufySmart Scale P1 and C1 is a breeze and their battery life lasts several months.

With EufyLife, you can add up to 16 users on a single account

Thanks to their simple design and intuitive app, setting up the Eufy Smart Scale P1 and C1 is a breeze. Once you’ve unboxed the scales, you simply need to insert 3 AAA batteries, which are already supplied. The scale lights up soon after, indicating it’s powered. According to Eufy, the batteries should last several months to a year in normal use.

You can set your preferred unit manually using a switch on the underside. Or, you can change the settings via EufyLife. After selecting your measuring unit, you pair the device to the mobile app and follow the on-screen instructions. Like any smart scale, you’ll have to enter basic information to calculate your BMI first. Once done, you can start weighing yourself.

The Eufy SmartScale P1 and C1 can add up to 16 users on a single app. However, the data is only recorded on one phone and account.


The Eufy Smart Scale C1 is a more value-for-money option than the Smart Scale P1.

If you’re keen on upgrading to a smart scale, the Eufy Smart Scale P1 and Smart Scale C1 are solid budget options. They’re well-designed, easy to set up, and pair with an intuitive mobile app. In terms of accuracy, these devices are consistent with their bodyweight measurements, too. The only downside is that there is no athlete mode for users with different weigh-in needs.

Given their similarities, which model should you buy? Our pick is the Eufy Smart Scale C1. While it tracks two metrics fewer than the P1, these measurements don’t impact your overall body composition readings. Its lack of ITO technology isn’t a big deal, either. In short, you can live without the add-ons that differentiate the pricier P1 from the C1.
