Tracking Made for PCOS

If you have polycystic ovary syndrome, you know that most period trackers don't work for you. They assume regular 28-day cycles and fail miserably when your period arrives weeks early - or doesn't arrive at all. Eve Day is different.

We built Eve Day with PCOS in mind from the start. Our AI adapts to irregular cycles ranging from 21 to 90+ days, learns your unique patterns, and provides predictions that actually reflect YOUR body - not some textbook average.

PCOS-Specific Features

When you set PCOS as your health condition during setup, Eve Day automatically adjusts prediction algorithms, symptom tracking options, and insights to match your needs.

Intelligent Irregular Cycle Tracking

Eve Day's AI doesn't panic when your cycles vary by weeks. Our system categorizes your cycle regularity and adjusts predictions accordingly:

Adaptive Prediction Ranges

Long Cycle Support

Unlike apps that max out at 35 days, Eve Day comfortably handles cycles of 60, 90, or even longer. We know PCOS cycles can be unpredictable, and our tracking adapts to whatever your body does.

Missed Period Detection

Eve Day helps you distinguish between a PCOS-typical long cycle and a genuinely missed period. Our health flags alert you when patterns change significantly, so you can discuss them with your healthcare provider.

Track PCOS-Relevant Symptoms

PCOS affects far more than just your period. Eve Day helps you track the full range of symptoms that matter for managing polycystic ovary syndrome.

Comprehensive Symptom Logging

Pain Tracking

Lifestyle Factor Correlation

PCOS symptoms often correlate with lifestyle factors. Eve Day tracks sleep quality, stress levels, exercise, and diet flags to help you identify what makes your symptoms better or worse.

AI Predictions Designed for PCOS

Our machine learning models were trained to handle the irregularity and variability that comes with PCOS. The AI learns YOUR patterns, not a generic cycle model.

Condition-Specific Models

When you select PCOS as your condition, Eve Day uses specialized prediction models that:

Pattern Discovery

Despite the irregularity of PCOS, patterns often exist. Eve Day's AI identifies correlations like stress-triggered cycle delays or sleep-related symptom flares that you might not notice on your own.

Educational Insights

Eve Day provides PCOS-specific educational tips on managing symptoms, including the role of stress, insulin, and lifestyle factors in PCOS management.

Health Reports for Your Doctor

Managing PCOS often requires working closely with healthcare providers. Eve Day helps you make the most of every appointment with comprehensive health reports.
