InBody provides segmental bioimpedance analysis in a gym or clinic setting. FitCommit gives you a photo-based body scan you can repeat at home and connects it to your targets, Future You, and food log. Choose based on the setting and detail you need.
Photo-based body scan accuracy
Good accuracy
Uses photo-based AI to analyze three photos (front, side, back) and measure body fat percentage, lean mass, and measurements for trend tracking.
InBody uses bioelectrical impedance analysis (BIA) by sending small electrical currents through your body via hand and foot electrodes. It measures resistance to estimate water content, lean mass, and fat mass across different body segments.

Accuracy ranges on this page are directional estimates from body-composition research. These methods do not measure the same physical signal, so the cleanest comparison is trend consistency, cost, access, and whether you need a clinical-grade baseline. Use one method under consistent conditions, and use clinical testing when a medical or research-grade answer matters.
FitCommit connects a photo-based body-composition scan, food tracking, and a Future You preview in one system. Each tool uses the same plan and progress inputs.

AI body scan, food tracking, and transformation preview. One system.
FitCommit can use your lean mass with the Katch-McArdle formula instead of relying only on height and weight. The TDEE result remains an estimate and should be adjusted against your real trend.
A compatible iPhone camera, consistent lighting, and form-fitting clothing. Take three photos: front, side, and back. No special measurement equipment or appointment is needed.
DEXA is the better choice when you need a clinical baseline. FitCommit is built for convenient at-home trend tracking. It is as precise as an InBody scan, not a DEXA scan.
No. FitCommit measures body fat and lean mass for progress tracking. It does not diagnose any condition, and a DEXA scan is the better choice when you need a clinical baseline.
