## What is Natus?

Understanding your cycle starts with observation.

Natus is a private natural fertility journal designed to make menstrual cycle tracking simpler, more organized, and faithful to what you observe each day.

No automatic predictions. No fertile-day or ovulation determination. Natus organizes the information you enter so you can review your history clearly over time.

With Natus, you can record:

• sensations and appearance observed throughout the day
• cervical mucus and bleeding
• menstrual cycle information
• chart markers and annotations
• sexual intercourse
• symptoms and medications
• basal body temperature
• saliva crystallization
• personal notes

REVIEW YOUR HISTORY

View your entries in organized charts and follow your observations across each cycle while keeping your history in one place.

COUPLE TRACKING

If you choose, you can share your tracking with your husband. This allows both of you to participate in recording information and follow the same journey together with greater involvement and organization.

INSTRUCTOR SUPPORT

You can also invite an instructor to review your records, making individual guidance and follow-up easier.

REPORTS

Generate organized reports of your observations to save, share, or use during professional follow-up, including MOB report options.

NATUS PREMIUM

Essential tracking features remain available for free.

Natus Premium includes additional features such as tracking with your husband, instructor support, basal body temperature, saliva crystallization, and advanced reports.

PRIVACY AND CONTROL

Your information remains linked to your account, and you stay in control of your records and who you choose to share them with.

Natus was created for people who want to observe their cycle with attention, consistency, and clarity.

Your observations tell a story.
Natus helps you organize it.

Natus is a personal tracking and record-keeping tool. It does not provide diagnoses, determine fertile periods, prescribe treatments, or replace medical advice from a doctor or other healthcare professional.
