Your sperm aren't "today." They're the result of the last 74 days. Sperminal turns that invisible process into something you can actually see, track, and influence. Log your daily habits. Watch how they shape the four active batches of sperm your body is producing right now — each at a different stage, each responding differently to what you do today. This isn't guesswork. It's a living pipeline. HOW IT WORKS Your body is always producing sperm across a ~74-day cycle, followed by ~2 weeks of maturation — a ~90-day window where today's habits quietly shape tomorrow's pipeline. Sperminal models this as four overlapping cohorts, each moving through the pipeline in real time. • Log key behaviours like sleep, exercise, alcohol, heat exposure, and illness • See instant projected impact before you commit your day • Track which cohorts are in their critical window — where your actions matter most • Follow your overall trajectory: Improving, Stable, At Risk, or Declining AT A GLANCE • Live Impact Preview — see how today's choices will affect your future • Critical Window Alerts — know when it matters most • Daily Focus — the single highest-impact action for today • Daily Reminder — a gentle nudge to log your day • 90-Day History — trends, heatmaps, and score tracking • Partner Sharing — share progress without exposing personal logs WHY IT'S DIFFERENT Fertility apps have always been built for cycle tracking. Sperminal is built for the other half of the equation — the side nobody tracks. Instead of waiting, testing, or guessing, you get a daily feedback loop tied to how sperm actually develop. BUILT ON RESEARCH The model is informed by published research on spermatogenesis timing, heat sensitivity, alcohol effects, sleep quality, exercise, and recovery from illness. A full list of references is included in the app. PRIVATE BY DESIGN No accounts. No cloud. No tracking. No ads. Everything stays on your device. Start shaping the 90 days ahead of you. IMPORTANT Sperminal is an educational, behaviour-awareness tool — not a medical device. It does not diagnose, treat, or predict any condition. The scores are simplified models based on research, not clinical measurements. Always consult a qualified healthcare provider for medical advice.
