Index S2
Garmin Index S2 is a scale from 2021, sitting in the mid-range band at an indicative $199.
It reads 5 of the 33 signals this comparison tracks. Nothing at all from heart and vitals, sleep, activity and fitness. Rarer readings it does take: bone mass, hydration, muscle mass and weight.
By sensor class: 2 at consumer grade. That grade is my classification of the hardware, not a lab test. Those readings come from bioimpedance electrodes.
It has an LCD screen. No subscription is required.
Wi-Fi body-composition scale; BIA weight/BMI/body fat/muscle/water/bone.

Turn a supported wearable into daily health scores
MyBodyAI reads Fitbit, Oura, Polar and Withings by logging in, and Garmin from a data export, then builds daily recovery, sleep, load and immune scores, a biological age estimate, and early warnings. Optional, and separate from this comparison.
This comparison is free and ad-free. I build and update it on my own. If it saved you hours of research, a coffee genuinely makes my day.
