BIATrack — Weight Plus Body Composition

Weight Is Just the Start.

Step on barefoot and the F2 measures weight plus impedance through 4-electrode BIA. With App setup, body composition can be calculated from the measurement data. Without the App, the scale works as a weight scale only.

StableBase

Step On. Read Fast. Move On.

The F2 keeps daily weighing simple: 260 × 260 mm footprint, slim 22.5 mm profile, 5 mm tempered glass, upgraded base structure, white LED display, auto on/off, and lb/kg switching from the rear button. Place it on a hard, flat floor for stable readings.

Routine Accuracy

Consistency Starts With Setup.

Place the scale on a hard, flat floor and measure barefoot at a similar time each day. Body composition mode is for adults 18–65 within 100–220 cm height; outside that range, use weight-only tracking.

Works fine, but slight medical thing i did not realize

Great, but to the rare person with a pacemaker or dbs( i have a dbs) you 100% should not use this scale.
It works by passing a electric pulse(small but still) through your body apparently did not know, perhaps it will save someone else some time.

Easy to use

This scale has a nice, clean design and the large electrode plates make it easy to get a good reading. It measures more than just weight, including BMI and body fat, which is useful for keeping track of overall progress. The app connection is convenient for viewing and tracking measurements over time. The 400-pound capacity is also a nice feature. Setup was straightforward, and the scale responds quickly when stepping on. Overall, a useful option for keeping an eye on weight and other body measurements at home.

Easy price, attractive and small

Accuracy. The first thing this scale did was lie to me about my weight. Not a happy experience. (H.o.r.r.i.b.l.e.) But then I looked at the directions and saw that I shouldn't have it on carpet. User error. Since then it matches what my doctor's office says. It's not that I necessarily agree with what she says either, because time of day, shoes, blue jeans, phone in pocket...but at least I disagree with them both equally. So accurate together.

The display is great. It tells me all the information I could probably ever need. I have not connected it to my doctor's health connectivity lifetime intrusion because I have enough trouble with my ring telling my watch I need to get up and stretch, let alone widening the audience.

The app is great. It was easy to find and download -- but only after scanning the QR code. The apple app store gave me a giant run around of some other ten hundred five apps it thought I meant.

Two AAA Duracell batteries were included. I liked that during the setup because I was expecting to need to plug it in to a charging cable which would be awkward.

More connectivity is available than I want to use.

The price is really amazing for what this does.

My first smart scale

This is my first smart scale and I really love it. I've owned plenty of regular bathroom scales before, and the first thing I noticed with this one was actually the size. It's much more compact than the scales I've had in the past and doesn't take over a corner of the bathroom.The scale itself also feels really stable when you step on it. The surface is solid, my feet sit naturally on the metal contact areas and the weight shows up quickly and is easy to read. I've stepped on it a few times back-to-back just out of curiosity and the readings have been consistent, which is obviously what you want from a scale.Then there is the app. This is where I finally understood the benefit of a smart scale. Instead of seeing a number and forgetting it five minutes later, I now have an actual history and can see the trend. There is a lot more body data available too, probably more than I personally need, but I like having it there.My only small usability wish is the syncing. From my experience I have to open the app when I weigh myself for it to record the data. I would love to just step on the scale and have it sync later without having to think about my phone.Still five stars for me. It looks clean, feels stable, the display is easy to read and I absolutely love how little bathroom space it takes up.

Easy-to-Use Smart Scale with Helpful Tracking Features

I’ve been tracking my weight and health goals for quite a while, so I appreciate having a scale that does more than simply display a number. Pairing it with the companion app was quick, and it automatically syncs measurements after each weigh-in. The app is easy to navigate and makes it simple to monitor progress over time.

The scale itself has a sleek, modern design that looks nice in the bathroom without taking up much space. It provides quick readings and appears consistent from one weigh-in to the next. The glass platform feels sturdy, and stepping on and off is comfortable.

Overall, this is a great smart scale for anyone looking to monitor their health journey. It combines accurate measurements with useful tracking features in an attractive package.

Smart, Affordable Body Tracking That Goes Beyond Just Weight

This smart scale stands out as a helpful tool for anyone trying to take their fitness seriously at home. Beyond basic weight measurement, it provides a wide range of body composition data like BMI, body fat, muscle mass, and hydration, which makes it easier to understand real progress over time rather than focusing on a single number. Setup is generally straightforward, and the companion app connects via Bluetooth to sync and store data trends over weeks and months. Many users find the visual tracking motivating, especially when trying to stay consistent with workouts or nutrition goals. The scale itself has a clean, modern design with a stable platform and large electrode areas that make standing on it comfortable and consistent for readings. Accuracy and repeatability are strong points, with readings staying consistent when used on a flat surface. It also includes practical features like multiple-user tracking and long-term data history, making it suitable for households. The main drawback mentioned is that the app experience can feel a bit complex or overwhelming at first, especially with the number of metrics provided. Some users also wish for clearer explanations of what each measurement means. Overall, this is a solid, budget-friendly smart scale that delivers a lot of health insight for the price and is especially useful for tracking fitness progress over time.

Accurate Scale... Even When You Don't Want It to Be

This scale has quickly become part of my morning routine, even if it occasionally gives me news I'd rather not hear. Apparently, it's really good at keeping tabs on my love for good food! 😄The readings have been consistent, and I like that it tracks much more than just weight. The app was easy to connect, and it's interesting to see things like body fat, BMI, and other body composition metrics over time. It's nice being able to watch trends instead of focusing on a single number.The scale itself feels sturdy, has a clean design, and the large display is easy to read. If you're trying to keep yourself accountable—or just need a reminder to skip that second dessert once in a while—this is a great smart scale. Overall, I'm really happy with it and look forward to watching the numbers move in the right direction... eventually.

you need an accepted Bluetooth device to operate the app

When I tried to download the app with more than enough space on my first generation I-phone SE with IOS 15, the app wouldn't open. Then I tried to download it on a Samsung Galaxy tablet S6 Lite with pretty much no additional apps or storage on it and it downloaded successfully. Then the next hurdle is you have to put in your height and age. Then you go stand on the scale, and the information gets sent by Bluetooth transmission and recorded in the app. The information you get in the app is confusing and it doesn't explain what the numbers mean. There are two different tiers of paid subscriptions that tell you more information about your progress, but it doesn't say if it will explain the meaning of the values. For instance, it gives you total body fat and body fat percentage as two different numbers written as percents.You have to hunt around on the app to find how to access all the data. I found it under generate personal report. You get a long list of different values. You get one for body fat, one for visceral fat, one for water, bone mass, muscle mass, protein, pounds of muscle etc.It turns out that if you don't input your height and age, it will only give you your weight. You can get that without connecting to the phone app.There is a number you can call for help, but it turned out the agent gave me the wrong information saying there was a connectivity problem with the scale instead of that the app simply didn't work with my phone. They were willing to send out another scale, but this was not the issue.I would like if you didn't have to fool with an app, and the data you want just showed up on the scale at least as far as body fat percentage. There needs to be some explanation by what they are measuring with the different read out values. Another issue is that there is no way to ever turn off the Bluetooth without taking out the batteries.It uses 2 AAA batteries that are included. It is a nice-looking scale, but the app is pretty confusing to navigate and interpret.

Nice smart scale for tracking progress

This smart scale is easy to use and has a clean, simple look. I like that it tracks more than just weight, including BMI, body fat, and other body composition measurements through the app. It is helpful if you want to follow trends over time instead of only looking at one number.The large electrode plates make it easy to stand on, and the display is easy to read. It also has a 400 lb capacity, which makes it more practical for different users. Overall, this is a good bathroom scale if you want basic smart features at an affordable price.

More Than Just a Number on a Scale

I recently decided to pay closer attention to my health and started tracking my weight more consistently. What caught my attention about this scale was that it offers much more information than a basic bathroom scale.Setup was straightforward, and the app connected without much trouble. Beyond weight, it provides additional body composition measurements such as BMI and body fat estimates, making it easier to track trends over time. I found it helpful to see more than a single number when monitoring progress.The display is bright and easy to read, and the larger electrode plates provide plenty of foot room. The scale feels stable underfoot, and repeated weigh ins produced consistent results when used on a hard, level surface.The app stores historical data, which makes it convenient to review changes over weeks and months. For households with multiple users, the tracking features can be especially useful.Overall, this is a solid smart scale that combines weight measurement with additional body composition data and app tracking. It is a useful tool for anyone looking to monitor health and fitness goals from home.

Far beyond a typical weight scale.

This FondCircle scale gives you so much more than a simple weight measurement, it will also give you a reading for 15 other body composition measurements, such as fat percentage, BMI, bone and muscle density, and many more. I wanted it to monitor my BMI and after downloading the app and pairing with the scale, along with my weight it automatically gave me both my fat % and BMI and records it for future reference. I must play with the app a bit more to figure it all out to get some of the other readings, but for now its giving me exactly the info I want. The scale is powered by 2 AAA batteries which are included.This is a nice contemporary looking scale and neutral colored to fit in any décor. I tested it with a 10-pound dumbbell 3 separate times and got 2 readings of 10.0 and one at 9.9 , so it is accurate within a tenth of a pound, which I’m satisfied with. The contact plates you place your feet on are large enough to create good conduction for providing accurate data, and the scale itself is rated for 400 Lbs. That currently equals two of me, so hopefully I’m in no danger of overloading it! At a price of less than 20 dollars, I just don’t think you will find a scale that looks this good, provides more data, and has this weight rating! In my opinion this offering by FondCircle is simply a great value.

Good Smart Scale for Home Use

This scale has been a helpful tool for monitoring my fitness progress. The measurements appear accurate and consistent, and the body composition information provides useful insights that help keep me motivated. The design is sleek and modern, and the platform feels sturdy underfoot.I deducted one star because I wish the display stayed illuminated slightly longer after stepping off the scale. Sometimes I need an extra moment to view all the information. Aside from that small issue, the scale has performed very well and has become part of my daily routine.

FAQs

Please read our FAQs page to find out more.

Can I use F2 without the FondCircle App?

Yes, but without App setup the scale functions as a weight scale only. Body composition tracking requires App connection and supported user profile information.

Why do I need to stand barefoot?

F2 uses foot-to-foot BIA. Bare feet must contact the electrode areas so the scale can collect impedance data for App-based body composition estimates.

Who should not use body composition mode?

Body composition mode is not intended for pregnant users, infants, or people with pacemakers or other implanted electronic medical devices. Users outside the supported body composition range should use weight-only tracking.

What is the supported body composition range?

Body composition mode supports adults ages 18–65 with a height of 100–220 cm. Outside this range, use the scale for weight tracking only.

Why are my body composition numbers different between measurements?

Hydration, recent exercise, bathing, food intake, foot contact, floor surface, and measurement timing can affect BIA estimates. Use the scale barefoot, on a hard flat floor, at a similar time each day.

What should I check if the scale does not turn on?

Install 2 AAA alkaline batteries in the correct direction. Place the scale on a hard, flat surface and make sure the startup weight threshold is met.
