About this app

sWeight is a weight loss tracker and body measurement app with on-device AI. Track your weight, BMI, and seven body measurements to see the full picture of your fitness transformation — not just what the scale says.

Most weight tracker apps stop at the number on the scale. sWeight goes further. Log your chest, waist, hips, left and right biceps, and left and right thighs alongside every weigh-in. Whether your goal is weight loss, muscle gain, or body recomposition, tracking body measurements reveals progress that a weight scale alone will never show.
