Step on and Lumen reads 18 dimensions of your body composition — from body fat and muscle mass to visceral fat and metabolic age — in under eight seconds. Each measurement syncs silently to your phone, turning a daily habit into a clear picture of how your body is really changing.
Weight alone hides what matters. Lumen separates fat, muscle, water and bone so you can tell whether a change is real progress or just yesterday's dinner.
Visceral fat and metabolic age are early signals of long-term health. Watching them trend gives you the chance to act while small adjustments still count.
Smart trend lines smooth out day-to-day fluctuations, so a hard week of training shows up as the win it actually is instead of a discouraging spike.
I lost 6 lbs in a month but the body fat percentage barely moved — turns out I was losing water, not fat. Lumen showed me that before I got discouraged. The eight-second read is real.
My weight bounces 3-4 lbs day to day and it used to mess with my head. The smoothed trend graph makes a hard training week look like the win it actually is.
Unlimited profiles means my wife, two teenagers and I all sync to our own accounts automatically. It just knows who stepped on. Genuinely impressive.
Looks gorgeous in the bathroom and the readings line up with my gym’s InBody machine within a percent or so. Took one star only because the app needed an update to connect at first.
