Why the name?
One day is a snapshot.
74 days tell a story.
Sperm development takes approximately 74 days. That makes a single good day—or a single difficult one—only one part of a much bigger picture.
74 helps you track habits and important events across that wider window, so you can build useful context without turning biology into a countdown or a promise.
Context, not certainty.
74 does not diagnose fertility, predict conception, or replace medical advice.

Still have a question? You’ll be able to reach us from inside the app.
Why is the app called 74?
The name reflects the approximate 74-day sperm-development cycle. It gives daily
habits and important events a useful timeframe, not an exact countdown or a promise of
a particular result.
Is 74 a medical or diagnostic app?
No. 74 is not diagnostic and not a 0–100 score. It offers educational context,
tracking, and organization. It does not diagnose a condition, interpret an individual
result as medical advice, predict conception, or replace a qualified healthcare
professional.
Where is my data stored?
Labs stay on the device. Your profile, daily logs, semen analyses, documents, partner
details, and AI history are stored locally on your device. Only the typed question
leaves the device: if you ask an AI question, only the text you enter is sent to the
secure service for processing.
Do I need to connect Apple Health or Health Connect?
No. Health connection is always optional. It can reduce manual entry by reading selected
activity and body data, but every core tracking flow also works manually.
Can 74 read a semen analysis automatically?
Not in the first version. You enter values manually so you can preserve the original
units, laboratory reference ranges, and context exactly as shown on your report.
Will I need a subscription?
Yes. Access to 74 requires an active trial or subscription. Current plans and localized
prices will be shown in the app before purchase, and you can manage your subscription
through your app-store account.
