Garmin Index S2 Review (2026)
In-depth review of the Garmin Index S2: Garmin Connect syncing, 16 profiles, and whether it beats Withings for Garmin owners.
Garmin Index S2 Smart Scale
The Garmin ecosystem pick: Wi-Fi syncing straight into Garmin Connect, 16 user profiles, and a bright, easy-to-read display.
Our verdict
The Garmin Index S2 is the best smart scale for Garmin owners, because it keeps weight and composition inside Garmin Connect, next to training, sleep, and calorie data, with no second app and no export dance. Its 16 user profiles suit large households, its Wi-Fi syncing never misses a weigh-in, and its bright display makes the morning routine quick. Outside the Garmin ecosystem the premium outlay is harder to justify, but inside it, the Index S2 is the natural and best choice.
What we like
- Wi-Fi syncing sends weigh-ins straight to Garmin Connect, so weight trends sit next to running, cycling, and sleep data in one place.
- Sixteen user profiles suit large households and teams far better than the 8-profile limit on most rivals.
- A bright, high-contrast display with a weather readout makes the morning weigh-in quick to read, even in a dim bathroom.
What to watch out for
- No direct Apple Health syncing, so Apple users need a third-party bridge or accept Garmin Connect as the home for their data.
- Composition metrics are fewer than Withings, with no segmental breakdown or heart readings, so health-depth buyers get less.
- The premium outlay is hard to justify outside the Garmin ecosystem, since the scale itself measures no differently from cheaper rivals.
Who it is for
Garmin watch owners who want weight and composition inside Garmin Connect alongside training data.
One app for training and weight
The Index S2's main asset is not a measurement but a location: Garmin Connect. Weight trends appear next to running load, resting heart rate, and sleep, so a weight change can be read against training changes rather than in isolation. That context is genuinely useful for athletes cutting or gaining weight deliberately, and it removes the friction of checking a second health app each morning.
Profiles and display for real households
Sixteen profiles is double the usual limit, which matters for large families, shared houses, and even small teams. The bright display shows weight clearly plus a weather readout, which turns the morning weigh-in into a quick glance rather than a squint at a dim screen. Carpet feet in the box help on softer floors, though a hard floor still gives the most consistent readings.
How it stacks up
Against the Withings Body Smart, the Index S2 wins on Garmin fit and profile count, while the Body Smart wins on modes, app polish, and composition breadth. Against the Withings Body Scan, the Index S2 wins on ecosystem simplicity, while the Scan wins on health depth. Against the RENPHO Elis Evo, the Index S2 wins on Wi-Fi reliability and ecosystem, while the Elis Evo wins on outlay and on-scale display.

Questions, answered
Does the Index S2 sync with Apple Health?
Not directly: Garmin Connect does not push weight to Apple Health without a third-party bridge. Apple users who want native Apple Health syncing should choose a Withings scale, which syncs directly, or accept Garmin Connect as the home for their weight data.
Is the Index S2 worth it without a Garmin watch?
Mostly no: without Garmin Connect as a daily habit, the premium buys profiles and a display rather than better measurement. Non-Garmin buyers get equal or better value from the Withings Body Smart or the RENPHO Elis Evo.
How long do the batteries last?
Up to 9 months on 4 AAA batteries, which is generous and means battery changes are rare. Heavy multi-user households will see shorter life, but even then the scale needs attention only a few times a year.
