THE SEXUAL HEALTH INDEX
One number that actually means something. Built from your own data.
Your daily Sexual Health Index is calculated from your morning check-in data across three sub-scores: Sexual Function, Recovery, and Load. After your first evening check-in and before your first morning check-in, you may see a clearly labelled STARTING ESTIMATE based on your onboarding answers. This is a personal tracking metric, not a medical score.
What the Index measures
Three sub-scores that each capture a different system. Function: morning erection quality and libido - the direct outputs. Recovery: sleep, HRV, cardio - the resources your body has to work with. Load: stress, alcohol, and training strain - the demands pulling in the other direction. Balance them and the Index moves.
How it's calculated
Your daily score is calculated from morning check-in data, not generated by the AI that writes observations. The onboarding-based STARTING ESTIMATE is a separate state, shown before your first morning check-in.
Why one number beats a dashboard
You don't have time to interpret twelve charts every morning. The Index gives you one number and a direction. The sub-scores tell you where to look. Weekly visual reviews bring together observations, a chart and an experiment to consider. They require sign-in and enough logged data. Comparisons appear only when comparable data is available.
WHAT YOU GET
Built for signal, not noise.
Deterministic scoring
Same inputs, same score. No AI drift, no hallucinations, no vibes.
Three sub-scores
Function, Recovery, Load - so you know which system needs attention.
Age-adjusted context
Compared to the median for your age group, not to nobody in particular.
QUESTIONS
What people ask before signing up.
Is the Index clinically validated?
It's a self-tracking tool, not a diagnostic. The inputs are drawn from established sexual-health questionnaires and lifestyle-medicine research, but the number is for pattern recognition - not a diagnosis.
How is it different from a wearable score?
Wearables measure the body's outputs (HR, HRV, sleep). The Index adds the subjective sexual-health signal - morning quality, libido, energy - that no wearable measures directly.
How long until my Index is stable?
About 10-14 days of daily logging. Rolling averages smooth out the noise.
Can I improve the score deliberately?
Sub-scores help you explore changes in your logs. Weekly visual reviews bring together observations, a chart and an experiment to consider. They require sign-in and enough logged data. Comparisons appear only when comparable data is available.
