📱 Baby Nara — AI Menstrual Cycle and Hormone Recording Notebook

Record your menstrual cycle and pregnancy preparations all in one place.

and even AI-based pregnancy test interpretation — we’ve included only the essential features for those preparing for pregnancy.

✨ Recommended for:

• Those who want to record their menstrual cycle and ovulation date every month

• Those curious about the meaning of hormone test results (AMH, FSH, LH, Estrogen) received from the OB/GYN

📅 Key Features

1. Menstrual Cycle Calendar

Enter your period start date, and it automatically calculates your ovulation and fertile periods.

Even if your cycle is irregular, it calculates your average cycle based on recent records and displays it at a glance via a fertile period band.

2. Hormone Level Recording & AI Reference Information Guide

FSH, LH, Estrogen (E2), Progesterone, AMH, Prolactin, TSH, etc.

If you directly input your OB/GYN hormone test results,

it automatically calculates whether the test date falls within the follicular, ovulation, or luteal phase based on your entered menstrual cycle.

Then, by comparing the results with reference values for each phase from the guidelines of the Korean Academy of Obstetrics and Gynecology and ASRM (American Society for Reproductive Medicine),

Claude AI provides general health information in easy-to-understand terms.

3. AI Pregnancy Test Interpretation

If you take a photo of your pregnancy test, Claude Vision AI

analyzes the intensity of the control line and test line to interpret the result.

This can be used as a reference when you are confused about faint lines or evaporation lines.

4. Pregnancy Preparation Community

This is a community where you can anonymously share experiences, test results, and tips regarding pregnancy preparation.

It operates safely with features such as likes, comments, and reports.

5. Health Report PDF

Organize your recorded menstrual cycles, hormone levels, and test history into a single PDF,

which you can use during your OB/GYN appointments.
