Index Smart Scale

Stay on top of your training by keeping track of your weight regularly whether you're working towards a goal or just maintaining. When you step onto Garmin's Index Smart Scale, don't expect to see a shaky needle trying to make up its mind about how much you weigh — like any other Garmin product, the Index is capable of recording a host of metrics. In addition to weight, the Index measures BMI, body fat/water percentage, bone mass, and muscle mass. It's also enabled with ANT+ and Bluetooth compatibility, so you can wirelessly upload your data directly to GarminConnect and analyze it against your goals and alongside workouts

By giving you access to more than just arbitrary BMI measurements and weight, you receive a more well-rounded idea of your strengths and weaknesses, which is more effective than relying on weight alone. The scale can store profiles for up to 16 users, which makes it useful for training groups and families, and it runs on four included AA batteries for up to nine months.

  • Garmin's body scale for getting fit fast
  • Wi-Fi connection for snycing and uplaoding to Garmin Connect
  • Measures weight, body mass index, body fat, skeletal muscle mass, and more
  • Recognizes up to 16 users
  • Up to 9 months of battery life

What I have notice

  • Familiarity: I've used it several times

This scale is perfect for keeping you in check and give you feedback about your health, but I notice that is not easy to synchronize with every device, using my phone (Samsung) I didn't have any problems connecting it into the wifi, but when I wanted to use my tablet (Asus) it was impossible to make it work.

Great addition to the Garmin family

  • Familiarity: I've used it several times

This fits in seamlessly with your garmin connect account. The set up really isn't tricky at all as long as you're within the wifi area of where you'll be setting it up.
Everytime you step on the scale it will log your weight and record it automatically into your account. This makes it very easy to habitually use the scale and track in detail your work and other specs over times. Body fat Percentage with any of these scales is hit or miss but everything else is pretty accurate.

Easy setup

  • Familiarity: I've used it once or twice and have initial impressions

I got this one up and running in a few minutes. Pretty easy setup. The garmin connect mobile app is pretty cool. I love the fact that it keeps a historical record on my weight, % fat, and other sort of metrics. It automatically picks when I'm using it or when my wife uses it.

What to expect from this scale:

    I've been using this scale consistently for a couple of months now, here are my honest thoughts. Out of the box, the scale is well built, looks clean and comes with four AA batteries which are supposed to last 9 months.

    Setup - Next you have to connect the scale to your WiFi network, this step can be a bit tricky. You must have the Garmin connect app downloaded on your phone/table/computer. Garmin connect then recognizes the scale via Bluetooth and connects it to your wireless network. Once you have this set up, everything else is a breeze.

    Interface – If you are the only user of the scale, you just step on barefoot and the onboard screen spits out your weight, BMI, body fat %, muscle mass in lbs, bone mass in lbs, and your body water %.

    Multiple Users – Every user must have their own Garmin connect account so that the scale can differentiate between each users (the scale can recognize up to 16). In order to add a user, you must be friends on Garmin connect, which then allows you to grant that person access to the scale. As long as you both aren’t within 10-20 lbs. of each other’s weight, the scale does a good job at automatically recognizing each user.

    Pros – Keeps track of your weigh ins through Garmin connect, this makes it very easy to see how your body changes over time. For serious athletes, I find this most useful in helping keep a target weight. When training starts to get intense, one may start to lose weight, or vice versa on active recovery weeks. This is also a great weight loss tool, as it shows how your muscle mass varies as you lose weight and gain muscle. (Keep in mind all of these metrics aren’t going to be exact, but will help give you a general idea).

    Cons – Tricky to set up and add users. Body fat % and body water % metrics aren’t too accurate, but you really can’t expect too much from an at home scale. Must be diligent in switching users if you are of similar weight, or your data will be skewed.

    If you’re looking to more closely track and keep and easy log of your weight metrics, this will be another solid tool to help you reach your goals. This will work especially well if you’re already in the Garmin ecosystem with bike computers/ watches.

    Great and easy to set up

    • Familiarity: I've used it several times

    Its a great scale, easy to set up and easy to use, gives a lot of information. The only cons I found is trying to add a second person to the scale, its a little confusing, after few tries I got it to work.

    Ongoing issues and busted after just 1yr

    • Familiarity: I've used it several times

    What can I say? The scale has issues. Setup is not flexible. Guest access is limited. Accuracy of readings except weight are dubious. Finally just after 1 year, I come home and find that it's not working and has "ERR2" displayed. Thinking that a simple "RESET" would do the trick, but oh no.. It won't reset, power cycle doesn't work, etc. Next step, check warranty. Oh just finished. Great. Thanks Garmin! Another well timed malfunction.

    Frustrated with this one

    • Familiarity: I've used it several times

    I have not been able to setup the scale to work, I have followed the instructions several times and still just gives me the weight and does not recognize me as a user, I've read that several people have the same issue. So I am feeling that just for getting weight info that is not even syncing with my phone it was too expensive

    Update: After a lot of trying I took my scale to other place and set it up with another wifi connection that worked, so I concluded that the scale does not get well with my home wifi, I would think a product like this was going to be better in compatibility but that is what it is


    • Familiarity: I've put it through the wringer

    It looks cool, has a lot of features, easy to set up, and wi-fi connection is stable. However, weight readings are inconsistent. It takes five or six attempts to get somewhat meaningful reading.

    So cool!

    • Familiarity: I've put it through the wringer

    I recently started a quest to be fit and healthy. Connecting this to Garmin connect is so easy! Garmin connect even syncs up with My Fitness Pal. Garmin has all the bases covered with this scale and all of their products. I am going to go get a DEXA body scan to see how close the body scans are with this scale. I will update after I get it.

    easy to set up, easy to use

    • Familiarity: I've used it several times

    super simple and sleek. no issues setting it up on wifi or iphone with the garmin app. tracks my info so i can see what's happening over time, and help reach goals.

    Super Awesome

    • Familiarity: I've used it several times

    My wife and I have Garmin watches and buying this scale had the purpose of getting a unified experience. The Garmin watches track all our daily activities and even our heart rate. The only missing piece was something to keep track of our weight changes and this scale was perfect.

    It is awesome. The configuration was very easy, and once I had it connected to our wireless network I could link it to multiple Garmin accounts using their mobile application.

    The scale is super smart, it identifies which user is on it based on weight and usage patterns. If two persons weight more or less the same, as soon as you see the wrong user name appear on the screen, you can tap on the scale to switch users. But in our case, since it is only my wife and I, and we have pretty distinctive weights, it has always identified the user correctly.

    The scale screen shows a lot of details: BMI, Body Fat, Skeletal Muscle Mass, Body Water, and Bone Mass.

    As soon as it finishes showing you all these stats, it immediately publishes them to your Garmin Connect account and you will see the data immediately in your mobile app or in your Garmin Express Website, where you can see charts of changes in your stats over time.

    There was only one small problem we had during the initial configuration phase. Our WI-FI is configured to restrict MAC addresses to a specific set of devices. So the first thing I wanted to do was to add the Garmin Scale MAC address to our while list in our WI-FI router, but the scale's MAC address is not defined anywhere in the product, or its box or its included documentation. So, I had to turn off this security feature in our WI-FI router momentarily in order to be able to configure the the scale properly and once it was connected to our network, I could see its MAC address in our DHCP table from which I took its number and configured it in our router and reestablished our security settings.

    Other than this small problem, everything is perfect and I am very satisfied with the purchase.


    • Familiarity: I've used it several times

    I already have a Tanita scale, which integrates with Garmin via Ant+ but is not Wi-Fi connected. So I decided to get this one to have a second in the house, something more convenient that did not require me to hold the Garmin computer in my hand to record my weight on the Garmin app. It connected easily to Wi-Fi after following the instructions. It's a beautiful looking scale. The screen is extremely easy to read. It seems to weigh me in at a lb or two heavier than my Tanita. Not sure why there is this discrepancy. Otherwise it is an excellent product, helping me to chart my weight decline as I get fitter, not fatter.

    Huge disappointment.

    • Familiarity: I've used it once or twice and have initial impressions

    I can not comment on the functionality of this scale as I never got past the set-up stage. I attempted to connect it to wi-fi using all 3 of the set-up options (Bluetooth via iphone, ant+ via my laptop, WPS via my router) but it just wont connect. Wasted 3 hours. Garmin support was completely useless, did nothing more than read me the set-up instructions that came with the scale and are published on their site. I often wonder how products that do not work make it through beta and to market. Sad really, as every other Garmin product I've owned has been great. Will be returning this scale.
