With the Garmin Index Smart Scale you can register your weight, body fat, muscle mass, etc., and automatically synchronize it to the Garmin Connect app via your WiFi connection. At the time of writing I’ve been using it for over a year now, in this Garmin Index Smart Scale review you will find my experience with the scale.
See below the current prices on Amazon.
Appearance
Measurements
The following body data is calculated by the scale:
- weight
- body fat percentage
- body mass index (BMI)
- body water percentage
- skeletal muscle mass
- bone mass
Setup and app
The first step of setting up your Garmin Index Smart Scale is adding four AA batteries, which are conveniently included. The back of the scale also has two buttons, one for synchronising and resetting and one to change the measurement unit to kilograms, pounds or stones.
If you don’t already have the Garmin Connect app on your phone, this is the time to start the installation. You’ll need the app to connect to your scale. The app will use bluetooth for the first synchronisation, but in daily use the scale uses WiFi to save your data. This means it is not necessary to have your phone near your scale to update your data in the app.
Below chart can be shown for a 7 day, 4 week or 12 month interval for each of data fields that are measured/calculated by the Garmin Index Smart Scale.
Many people have reported issues with synchronisation to MyFitnessPal, but I find the Garmin Connect app to provide sufficient information. In combination with my Garmin Vivoactive 3 all the information concerning health, weight, sleeping, etc. is located in one app.

Conclusion
The Garmin Index Smart Scale is a solid and nice looking smart scale that works well if you don’t mind using the Garmin Connect app. It’s therefore especially interesting for people who own other Garmin devices as well. I mainly like to see the daily changes in my weight, without needing to register this myself.
Overall this smart scale might be a bit pricey, but in general I’m very satisfied. You can find it here on Amazon.
Thank you for reading my Garmin Index Smart Scale review.
Do you experience any issues with the Wifi connections?
I haven’t had any issues with the Wifi connection!
since a year i have problems with body fat measurement on this scale, it’s always to low, a lot of other owners in the official garmin forum have the same probs, garmin knows it, but garmin don’t do anything
Hi! I had the exact same problem, it’s an easy fix, but you can only do this on the connect.garmin.com website, and not in the mobile app. Go to the top right corner where the watch icon is, click device settings for the index scale, then user settings, and last select the correct activity class number, anything higher than 6 means you’re like super athlete, and the scale automatically assumes your body fat is crazy low, so i’d recommend you stick to 6 or lower number.
Good luck! and i hope i’m not too late 😀
I’ve had the device for a few months now, using it daily. The software issues appear to have been worked out (this being many years after the product’s initial release!). Connectivity issues have been few and far between. (If you’re having issues, avoid connecting the device to a 5GHz WiFi band, which has shorter range; use a longer-range 2.4GHz band instead.) But the usefulness of the scale beyond BMI leaves a lot to be desired. I got it thinking it could give me more information than BMI, but that apparently is not the case. The body fat and muscle mass measurements are very closely correlated with BMI, which means the extra measurements aren’t very useful. Is my muscle mass really moving up and down in perfect sync with my weight? Come on.
I’m having the same results. I mainly love that I can step on the scale every day with my still sleepy head and my weight data gets registered without any effort from me in the same app where my other health data is saved through my Garmin watch. It might be a little expensive for that though.
Also, I should note that the Index Smart Scale now logs multiple measurements per day per account. I know because I’ve measured myself twice by accident, and I had to go back into Garmin Connect to delete the redundant measurement!
Hi Andrew, you are absolutely right. Garmin Connect was updated to be able to register multiple measurements per day now.
