T-Score grades your sleep, training, nutrition, sunlight, and cold exposure on the five levers backed by research to move testosterone. Auto-fills from Apple Health. Runs fully on-device.
Most "testosterone" apps are repackaged calorie trackers or supplement sales funnels. T-Score focuses on what actually works. Five daily habits with the strongest peer-reviewed evidence for moving endogenous testosterone. You get a score out of 100 every day.
Sleeping under 5 hours for a week cut young men's testosterone by 10 to 15% in Leproult and Van Cauter's 2011 study. Sleep is the single biggest lever.
Compound resistance training produces acute testosterone spikes and long-term androgen receptor density changes. Consistency matters more than PRs.
Pilz et al. 2011 found vitamin D supplementation raised total testosterone by ~25% in deficient men. Morning sunlight also anchors circadian rhythm.
Adequate dietary fat, zinc, and protein are non-negotiable. Severe calorie restriction and zinc deficiency reliably tank T.
T-Score is built from the ground up for one thing. Helping you actually move the needle on testosterone through daily habits, not hype.
