Can your smartphone really rival a $100,000 DEXA scan? What if the same device you use to scroll Instagram could also reveal your body fat percentage, fat distribution, and even your HRV?
I sit down with Jason Moore, founder and CEO of Spren, a company turning your phone into a precision biometric tool. We talk about how Spren compares to gold-standard lab equipment, why body composition tells you more than scale weight ever could, and why tracking trends is often more important than chasing perfect numbers. This conversation will show you how technology can bring lab-grade insights straight to your pocket.
Today, you’ll learn all about:
