InBody

Category-leading consumer BIA that tracks DXA closely at the group level, but a documented systematic offset and hydration sensitivity keep it below DEXA for absolute one-time values.

InBody 970S vs DXA: fat mass R2=0.96, fat-free mass R2=0.97, percent body fat R2=0.92, with a percent-body-fat mean bias of +2.54% (limits +7.74% / -2.67%); BodySpec independently reports a -4.0 +/- 2.8% body-fat bias vs DEXA. Frontiers in Analytical Science 2026 (InBody vs DXA) ↗

For its category the H20N is near-complete, directly measuring segmental lean mass across five body segments plus visceral fat and body water rather than estimating the upper body like foot-only scales.

Uses handlebar plus footplate 8-point tactile electrodes to take 10 impedance measurements at two frequencies across right arm, left arm, trunk, right leg, and left leg, plus weight, BMI, percent body fat, skeletal muscle mass, water balance, and visceral fat level. InBody Home Use (Dial H20N) ↗

Runs on replaceable AAA cells with a roughly year-long life and no charger to manage, though disposable batteries are less convenient than a rechargeable or wall-powered unit.

The home Dial unit is a battery-powered stand-on analyzer with no charging cable to manage; AAA cells last roughly a year of normal home use. InBody USA store (Dial H20) ↗

As a stand-on analyzer there is nothing to wear, and a barefoot measurement with the handlebar grip completes in well under 15 seconds, though the two-handed pose is a minor extra step.

Reviewer reports a full reading takes about eight seconds standing barefoot on the pads while holding the handlebar with arms extended, with results shown on an integrated display. KnowTechie hands-on review ↗

Data syncs into Apple Health and Samsung Health so trends can reach a coaching app like Vora, but the InBody app is Bluetooth-only, needs the app open to sync, and is less polished than Withings or Garmin, capping the score.

InBody support confirms the H20/H20N syncs from the InBody app to Apple Health, Google Fit, and Samsung Health via a HealthKit Sync toggle; connectivity is Bluetooth-only and now requires initiating the test from the app for results to sync. InBody USA support (Apple/Samsung Health sync) ↗

At $299 with no subscription it costs more than a basic smart scale, but it is one of the only consumer devices delivering true segmental multi-frequency BIA and stays useful for years as a trend tracker.

Official InBody USA price is $299.00 with no subscription, delivering an 8-point full-body measurement InBody cites at about 98% correlation with DEXA. InBody USA store ↗
