Spren: Body Composition Scan is a free Android app developed by Elite HRV that uses your smartphone camera to measure your body fat percentage, lean mass, and more with lab-grade accuracy. The app provides you with a multi-page PDF report that includes your body fat percentage, fat mass, lean mass, android fat, gynoid fat, and resting metabolic rate.

What sets Spren apart is its ability to provide results that are more comprehensive and accurate than bathroom scales or other apps. Additionally, Spren's results can be compared to healthy and optimal ranges from published research. The app's imaging algorithm has been validated by several independent peer-reviewed studies, making research-grade body composition analysis accessible to anyone with a smartphone.

Spren is more convenient than comparable methods like DEXA and underwater weighing. It helps you understand if your nutrition, fitness, and recovery programs are working for you, ensuring you're making progress toward your deeper health goals. With Spren, you can discover the true progress of your fat loss, lean gains, metabolic health, and longevity.
