How we rated the Garmin Index S2
Our own assessment of a device we do not sell, weighted across six dimensions: accuracy 30 percent, coverage 20 percent, battery 15 percent, value 15 percent, comfort 10 percent, app and ecosystem 10 percent. Every score links to its source: independent testing, or the brand's own page for current-model specs and prices.
Weight is excellent but the headline body-composition promise deviates materially from DEXA, so it is a trend tool not a lab measurement.
Weight MAE 0.18 kg over 210 paired measurements vs a Class III scale, but body-fat deviated 8.2% overall (11.5% in women) and muscle mass 13% vs DEXA across a 42-participant cohort. MedGrade (vs DEXA) ↗
It delivers the full single-frequency BIA metric set expected of a smart scale, which is what its category promises.
Reports weight, BMI, body fat, body water, skeletal muscle mass and bone mass, supports up to 16 users, and WiFi auto-syncs to Garmin Connect. DC Rainmaker ↗
Real-world battery is a standout for a scale, needing no charger and only an annual battery swap.
A 10-month real-world review reported impressive battery life approaching 1+ year on AAA batteries with no charging required. HMMuller 10-month test ↗
As a step-on scale it is effortless with a large bright instant display and no phone needed for a weigh-in.
Setup takes only a minute or two and the scale auto-identifies users by weight, flashing the recognized name so weigh-ins are near-instant. DC Rainmaker ↗
Garmin Connect integration is seamless and Vora can read its trends, but the platform is closed with no Apple Health export.
Praised for seamless Garmin Connect syncing into one dashboard, but a listed con is no Apple Health support and limited third-party connectivity. iMore ↗
No subscription and multi-year usefulness offset a list price that is high for a scale but routinely discounted.
$149.99 MSRP with no subscription, frequently found at $89-119, and it stays useful for years. HMMuller 10-month test ↗
