If you're only tracking one biomarker, body composition is where it's at.

Reliable body composition analysis is now possible through the smartphone camera using validated machine learning algorithms and computer vision. Go beyond the scale in your journey to look, feel, and perform better by focusing on what really matters —optimizing body fat and lean mass for optimal health.

Optimizing Body Fat

Remove the guesswork and hassle from tracking your body fat percentage and instead measure it with a quick selfie you can take all by yourself.

Gaining Lean Mass

Small changes in lean mass are difficult to see with the human eye—detect these changes effortlessly and track progress over time.

Improve Cardio-Metabolic Health

Most at-home scales lack the ability to measure fat distribution. Spren does this with every scan, providing insights into your cardiac and metabolic health.

Slow Down Your Biological Age

Using evidence-based machine learning algorithms, Spren measures small changes in body composition—empowering your quest to slow aging.

Keep Track of Your Body’s Most Important Biomarkers for Fat Loss

Spren empowers you with the data that truly drive positive changes in fitness and performance.

Biomarker/Insight

Description

Body Fat (%)

Fat mass / total mass; the proportion of your body that is made up of fat.

Fat Mass

Total weight of your fat mass (lbs/kgs)

Lean Mass

Total weight of your body from non-fat sources like muscle, organs, water, connective tissue, etc. (lbs/kgs)

Android Fat

Body fat around the trunk and upper body; an increase in android fat is associated with an impaired glucose tolerance and insulin resistance (higher risk of type 2 diabetes) (lbs/kgs)

Gynoid Fat

Body fat that forms around the hips, breasts, and thighs; often referred to as “reproductive fat”. The ratio of this to android fat is also related to risk of type 2 diabetes and cardiovascular disease (lbs/kgs)

Resting Metabolic Rate

Minimum daily calorie requirements needed to sustain your basic life-sustaining functions.
