Index S2, Smart Scale with Wireless Connectivity, Measure Body Fat, Muscle, Bone Mass, Body Water% and More, White (010-02294-03)

I’ve been using the Garmin Index S2 Smart Scale for a while now and it’s been a great addition to my overall fitness tracking setup. The setup process was quick and easy, and it paired right away with Garmin Connect and my Garmin Fenix 8. Once connected, everything syncs automatically, which makes tracking progress really convenient. Step on the scale and the data shows up in the app without having to think about it. What I like most is how well it fits into the Garmin ecosystem. It tracks a wide range of metrics like body fat, muscle mass, bone mass, and body water, and all of that data helps contribute to Garmin’s overall health insights like projected fitness age. Seeing those trends over time is really motivating. Like any smart scale, the body composition numbers should be viewed as close estimates rather than exact measurements, but they’re very useful for tracking progress and trends over time. Overall, this is a well-designed smart scale that works perfectly with Garmin devices. If you already use Garmin wearables like the Fenix series, this is a great way to round out your health and fitness tracking. Highly recommended.

When I buy a new product like this scale I look through the online reviews. I usually start with 1 star and then look through the others higher reviews. I noticed thst this scales one star reviews complain about WIFI connectivity, set up difficulty and then there are extensive reviews on the accuracy of the BMI and other measurements. I just opened the scale 15 minutes ago, put the batteries in the scale, it immediately paired on the first try with the Garmin Connect app on my iPhone. I then connected to my home WIFI with no issues on first try. The scale took about 10 minutes to up date its internal software. I stepped on the scale and it ran through its first calculations. They are pretty spot on. I’m replacing this with a fitbit scale so the data all pairs with the connect app. The fitbit scale is pretty accurate and the Garmin scale came back with the exact same BMI and body fat % the FITBit measured. I’ll have to see how it works as I get into shape and if it changes, or if I have additional problems. For now, right out of the box, scale worked flawlessly, and on the first set of measurements, it appears to be spot on with my Fitbit scale.

I wanted to love this scale, but sadly this scale just doesn't work the way that it should. The scale does not connect to certain WiFi networks and will not consistently sync your data to your Garmin Connect account. For this reason, I am returning this scale. More details below: I am in the Garmin Ecosystem. I have the Forerunner watch, the Edge bike computer, the cadence sensors, the speed sensors, and the Garmin Connect application. I like the quality of Garmin's products. I like the way they are designed around their users (e.g. The Forerunner watch uses buttons instead of a touch-screen because a touch-screen doesn't work with sweaty hands). They meet my needs and they work consistently. I wanted to love this scale, but it does not meet Garmin's quality standards for use. I wanted to get a scale that would record my body metrics and sync my data to Garmin Connect. I looked at some third party offerings, like Withings, but found that most of the time I would have to sync my data to one app, then walk it through another app, before I could get it into Garmin Connect where the rest of my health and performance data is. For this reason, the Garmin Index S2 made the most sense. It would sync all of my data to Garmin Connect and I could stay within a single application. When I opened the box, I was very impressed with the build quality. The scale is quite solidly built. In the box, you get 4 batteries, and some extra feet for using the scale on a carpeted surface. I popped the included batteries into the scale and started it up. Setting up the scale seems simple at first. You pair the scale to your phone using Garmin Connect, then proceed with the setup process. You add a nickname for yourself (The scale can sync to 16 unique users), and then you input your WiFi details. The scale says it is online, and you're ready to go. Simple... Or so I thought. I stepped onto the scale, and it gave me my weight. But instead of recognizing me as the user, the only user on the scale at this point, it says I am a guest user. Well that is odd, why wouldn't it recognize me? I go onto the Garmin forums looking for help. The scale, despite having Bluetooth, does not use Bluetooth to sync anything. It is only used for initial setup. Instead, the scale uses WiFi to sync data. I find that some users are also having trouble with their WiFi networks, and that pairing it to their phone as a hotspot works better. So I give this a try to add my phones hotspot as a WiFi network. The way that you do this is a bit unintuitive. You hold "Reset" on the bottom of the device, which doesn't actually reset the scale, but instead puts the device back into Bluetooth pairing mode. Once it is in this mode, you can add another WiFi network to your device. Note that if you do this, your scale will have a status of "WiFi setup incomplete" within your Garmin Connect devices section. So now, with my phones hotspot on, I try weighing myself again. This time, it recognizes me correctly, and gives me my body composition data as well (BMI, Bodyfat %, Muscle mass, etc.). But when I go into my Garmin Connect application on my phone, it still does not show up. The data just doesn't want to sync over. I try a few more times before it finally shows anything in my app. The syncing seems to be really inconsistent. I've had it sync over within a couple minutes, and I've had it take as long as several hours. The scale just doesn't want to sync over WiFi. Garmin's website is not helpful when it comes to troubleshooting. Is it a port issue? Does it need a reserved IP address? Does it need 2.4Ghz or 5Ghz WiFi? Why doesn't the device work over Bluetooth when it knows the user that is using it (and you can tap to select other users if it ever gets it wrong)? The primary function of this scale is to measure my body composition and weight, then sync it to Garmin Connect. It needs to work more reliably and conveniently than if I want to mark this data myself, manually. But at this point, it doesn't do that. For that reason, I am returning this scale. I am extremely disappointed in this scale. It is clear that Garmin released a product that was not fully thought out.

Awesome tool for athletes and anyone trying to track progress.

I’ve read reviews saying it is difficult to set up, but I thought set up was easy. Connects easy with Garmin connect app. Display is bright and readable. I question the accuracy of body composition measurements, but I also don’t know what can be reasonably expected from a home scale. It is an expensive scale for what it does, but the connectivity and app integration is nice.

Love my Garmin S2. I have two of them. One at my house and one at my sister's when I stay there. Long as you have good wi fi and blue tooth. It's perfect. I use it every day. I have the Garmin blood pressure monitor, the bicycle computer, the bike peddles that give power results and a bike rear light with radar detection . Why because it motivates me to measure my results. Rode my bike 2200 miles in 2025. These devices show results. Measurehhh to Motivate. Everything becomes historical data in my Garmin Connect App. Happy with the accuracy of the scale its readability.

Is so inacurate, I wouldn't bother, there's better ones for €40

Facile à installer et à utiliser. C'est garmin.....

We were put off by the reviews and nearly didn't bother with this, but they're really great scales. Having them on a flat, stable surface is important (our bathroom floor has slightly uneven tiles, so we have it on hardwood elsewhere). A light tap with your toe activates the scales. No home device is ever going to be as accurate as a DEXA, but the readings are pretty accurate - we tested the body fat % with callipers, and the scales seem to be brutally honest 😂 The display on the scales is very clear. Pairing this with a Garmin watch and Cronometer gives us online dashboards (not just phone apps) that supply enough stats to keep us nerdily motivated!

After purchasing these from Amazon UK, I received an invoice from FedEx for £39.07 for import duty, argued that Amazon were the importer but they wouldn't budge and I've had to pay this. The scales look good, weigh accurately but as for some of the other features I'm very dubious of their accuracy. For instance if my weight goes up by 1Kg after the weekend it shows my muscle weight being higher by a corresponding percentage which of course is nonsense, similarly if my weight goes down. The initial body fat percentages were far higher than the professional machine I'd been using but Garmin say in their literature if you have your own figures from a Dexa machine or similar to manually enter these body percentages and then miraculously it simply mirrors them going forwards, altering the muscle mass as your weight varies week to week. It seems that they know their own machine isn't accurate - A waste of money if you want to measure performance /gains over a period - according to these scales and the way they work, all I need to do is stuff my face to put on 5Kg and it will say I've put on 1-2Kg of muscle, regardless of the body composition.

I had to buy this particular scale as my Garmin Vivoactive 5 watch will not allow manual body fat input. You have to buy the scale (sold separately) if you want to maximize your watch's usefulness. The scale works great and set up is a breeze. Contrary to some articles found online, you DO NOT need to buy an ANT+ dongle to connect to your computer. The scale will share date with your devices via wi-fi. Scale accuracy is on par with other electro impedance scales - so/so. Great if you're looking for a general trend, poor if you require spot-on accuracy.
