Safr - Pregnancy Prevention

Safr is built to help you prevent pregnancy using real cycle data

Most apps rely on averages. Your body doesn’t. Safr uses the data you log to give you clear, personalized insight into your fertility and pregnancy risk.

Here’s how Safr works:

1. We use real science.

Safr is based on established research from sources like the Mayo Clinic, Cleveland Clinic, and leading reproductive health studies. Your cycle follows biological patterns, and we use that data to understand yours.

To estimate your fertility and pregnancy risk, we look at:

- Your cycle history and patterns
- Ovulation timing and biological signals
- Cervical mucus (a key fertility indicator)
- Daily symptoms and logs over time

Most apps assume a fixed cycle length. Safr adapts to your body. The more consistently you log, the more accurate your predictions become.

2. Know your pregnancy risk every day.

Safr gives you daily fertility probabilities and clear risk levels so you always know where you stand. By combining your cycle data with real-life inputs like sex and protection, Safr reflects your actual risk at any moment.

3. We also offer a smarter way to check pregnancy likelihood.

Safr’s virtual pregnancy test uses your cycle timing, activity logs, and known biological patterns to estimate your chances of being pregnant. Our algorithm combines these inputs to generate a structured, data-driven likelihood.

Safr offers premium features through subscriptions and in-app purchases, including fertility insights, pregnancy likelihood calculations, cervical mucus analysis tools, and more personalized predictions.
