# 74 — Your private male fertility companion

Canonical page: https://74-app.com/

74 is a private tracker for the approximate 74-day sperm-development window. It helps you keep daily habits, semen analysis results, and partner planning in one calm view. Real lab results in context — not a fertility score, not diagnostic.

## Why 74

Sperm development takes approximately 74 days. That figure is a useful average, not a stopwatch. One day is a snapshot. 74 days give context. 74 does not diagnose fertility, predict conception, or replace medical advice.

## What 74 helps you keep in one place

- Daily check-ins for sleep, exercise, hydration, food, alcohol, stress, and other useful context. A transparent lifestyle score shows what shaped your day — it is not a 0–100 fertility score.
- An approximate 74-day timeline for check-ins, analyses, and meaningful events, without implying that one habit caused a result.
- Semen analysis values, units, reference ranges, dates, notes, and documents, with compatible trends over time. Labs stay on the device.
- One-off fertility questions in plain language, with clear guardrails. Only the typed question leaves the device.
- Partner fertility windows and discreet reminders, without exposing sensitive details on the lock screen.

## Privacy

Your profile, logs, analyses, partner details, documents, and history stay locally on your device. When you ask AI a question, only the question you write is sent for processing.

## What 74 is not

74 is educational, not diagnostic. It does not diagnose a condition, interpret an individual result as medical advice, predict conception, or replace a qualified healthcare professional. It is not a 0–100 fertility score.

Optional Apple Health or Android Health Connect sync is read-only and never required.
