Our verdict
Where it wins
- Syncs over Wi-Fi straight to Garmin Connect, so a reading uploads even when your phone is in another room
- Feeds the same Garmin Connect app used by Garmin watches and bike computers, giving one combined view of weight and training data
- Supports up to 16 user profiles with automatic recognition, more than most household scales in this roundup
- No subscription required to see weight, trend, or body composition history
Where it loses
- Body fat, skeletal muscle mass and the other body composition numbers come from bioelectrical impedance and are estimates, not lab measurements
- At $199.99 it costs roughly eight times what the budget pick in this roundup costs, and the ecosystem benefit only pays off if you already own Garmin gear
- Star rating on Target trails the other scales in this roundup, with several buyers reporting Wi-Fi setup and sync issues
The Index S2 is not the best scale on paper, it is the best scale if you already live inside Garmin Connect. Wi-Fi syncing means a weigh-in shows up next to your run and sleep data with no phone required, and 16 user profiles cover a large household. Buyers with no other Garmin devices get little extra for the $199.99 price over cheaper Bluetooth scales, and the comparatively lower star rating on Target suggests the Wi-Fi setup is not always smooth. Skip it unless a Garmin watch or bike computer is already part of your routine.

More on the Garmin Index S2
Common questions
Does the Index S2 need a Garmin watch to work?
No, it works as a standalone Wi-Fi scale with the free Garmin Connect app. The main advantage of owning one shows up if you already use Garmin Connect for a watch or bike computer, since weight data then sits alongside your training data automatically.
Is there a subscription fee?
No. Garmin Connect is free to use for weight, trend and body composition history, unlike the Withings Body Smart, which reserves some features for a paid Health+ plan.
How accurate is the body fat reading?
Like every scale in this roundup, it estimates body fat and muscle mass using bioelectrical impedance rather than measuring them directly. Treat the numbers as a trend line, not a clinical result.
How many people can share one Index S2?
Garmin says it supports up to 16 user profiles with automatic recognition based on weight and body composition patterns.
