Eufy P3 smart scale review: How it works
If you’re new to smart scales, they are a clever bit of kit that can give insight into not just your weight, but also other body composition statistics, including muscle mass, body fat and more.
They work by sending a small (safe) electrical current through the body to measure body composition. You stand on the scale barefoot and the reading will then provide detailed health insights about your weight, body fat percentage, bone density, muscle mass and more.
When measuring for the first time, place the scales on a flat surface and select your user profile so it records the reading for the right person (the scales are meant to automatically recognize users based on their previous stats). After measuring, your weight and some of the other metrics will be shown on the screen.
For more detailed body composition data, you need to download the Eufy Life app, available for free via iOS and Android, where you can view it.
You can’t feel the electrical charge and it’s safe for most people, unless you are pregnant, have a pacemaker, or medical implant. If any of these apply to you, speak to your health professional first before using one.
Smart scales can vary in accuracy but they are still a useful way to track changes in body composition, and can be helpful if you are trying to lose weight or get fitter.

The Eufy P3 smart scales are well designed, minimalist and easy to set up and use. The black model we tested comes with four AAA batteries, and you can change the weight metric between kilograms, pounds or stones by pressing a small button on the back.
It’s super fast to set up, and comes with a user guide. You can use the P3 without its accompanying Eufy Life app, but you’ll only be able to see your weight.
When you download the app, it runs you through Bluetooth and Wi-Fi setup, and all you need to do is set up your profile and stand on the scales to take your first reading.
The scale is made from black plastic with a tempered glass top, which looks really smart but smears easily and is delicate. You would not want to drop anything on this, or indeed drop it. It is also slippery when wet — so avoid using the scale straight out of a bath, shower or sauna.
Turn it over and you’ll find the battery compartment, unit change button and four anti-slip rubber feet to keep the scale from tipping over.
It has a large and colorful display, which is easy to read. It also has battery, Wi-Fi and Bluetooth indicators so that you know where you stand with charge and connection. You can tell when the power is on because the Eufy’s “e” logo will be lit up in the center.
The appliance has a wide footprint (12.8 x 12.8 inches / 32.5 x 32.5 cm) and weighs about 70 oz (2 kg).
Download the free supporting Eufy Life iOS or Android app to connect via Bluetooth or WiFi (5G not compatible). Here you will find more detailed analysis of your body composition stats including weight, BMI, body fat, muscle mass, heart rate, basal metabolic rate (BMR), water, body fat mass, lean body mass, bone mass, visceral fat, protein, skeletal muscle mass, subcutaneous fat, metabolic (body) age and body type.
You can view these stats by day, week or month. You can also export a report on a certain date or multiple dates, and track your progress on an individual graph for each metric via the Trends section.
The app also allows you to export results as a PDF or image rather than a CSV spreadsheet-style file. You can also view all your history, and look at any unmatched or unfamiliar data for you to assign to a user. This is helpful if you encounter issues with matching results to different users.
When you click on a stat the P3 explains what that stat means, gives some detailed insight into whether your reading is low or high, and some tips for how to change this. You can swipe left or right on the app to scroll easily between stats. You can customize these metrics on the app to prioritize the ones you care about the most.
Click on Data Analysis and you can set a goal for the different body stats, so if you want to lose body fat, you can input a target you want to work towards.
There are unlimited users on the Eufy P3 smart body fat scales and it also has baby, pregnancy, pet and athlete modes.
It comes with a calorie intake feature which allows you to add your meals and drinks and set a daily kcal goal. However, there’s no option to scan the food via barcode (like on MyFitnessPal), so everything has to be entered manually.
The default setting in the app sends push notifications reminding you to weigh yourself daily, which is ill-advised and could be triggering for some, and lead to disordered behavior. I immediately unchecked this each day to turn it off, but that was a pain.
Eufy P3 smart scale review: Accuracy and performance
The user guide boasts that the P3 has high-precision sensors, but I noticed that it was actually a little too sensitive. During testing, I would tap the scale with my foot to try and change the user but it would often switch back to the weight screen while I was working my way through the different profiles, attributing my stats to the wrong person.
Once you get a reading, however, they are satisfyingly detailed, and it’s very beginner-friendly, as it spells out in layman’s terms what each metric means, along with your rating (for example, low, high) and lifestyle tips to make changes.
The P3 measures 16 different body composition stats and the data is tracked on graphs so you can review your progress over different periods of time.
You can set whether you want the scale to show your weight in pounds, kilograms or stones in the app, and it remembers the setting. You can also use a button on the bottom of the scale to switch between unit types, although when the app connects, its settings will override the button.
If you are pregnant or have a pacemaker or other ICD (implantable cardioverter defibrillator, a battery-powered device implanted under the skin that monitors and regulates the heart rhythm), you can use Simple mode to disable the electrical signals used to measure bioimpedance for body fat and stats. The P3 will then turn into more of a traditional scale, recording only your weight and foregoing the other measurements. It also has a pet and athlete mode.
The P3 will automatically distinguish between users as long as their weights are dissimilar enough. There seems to be about a six-pound discrepancy between users before you have to manually switch the user profile in the app.
The P3 connects to some of the best fitness trackers, including Apple Health, Google Fit and Fitbit, but it would be nice if it worked with other mainstream health and fitness apps.
The app is easy to use, but results can vary. The Eufy P3 reading put our tester at 35.1% body fat compared with a reading of 31.5% on the Renpho smart scales (the scales that proved to be most accurate in our testing and comparisons with a professional body composition machine at the gym).
Our tester’s body water reading was 46.3% on the Eufy and 46.9% on the Renpho, so not dissimilar; however, their Basal Metabolic Rate was measured at 1,215 kcal compared with 1,365 kcal on the Renpho. Our tester’s weight reading also seemed to fluctuate, varying by as much as three pounds despite readings sometimes being taken within minutes of each other.
Eufy P3 smart scale review: Verdict
The P3 is a neat little smart scale, fairly affordable ($99.99) with a ton of metrics and some useful intel and tips that could contribute to a healthier lifestyle. It’s fairly accurate for home scales, well made and durable.
It’s easy to set up and use and it syncs easily with the app. The main complaints are that it doesn’t always differentiate between users, smears easily and doesn’t link with many third-party apps. It also reminds you to weigh yourself with push notifications by default, which could lead to disordered behaviour.
But if you’re looking for a decent smart scale that tracks a lot of body composition metrics and provides some useful insights in simple language, this is a good option.
