What Preeo Helps With

Understand your cycle without the homework.

Preeo simplifies health tracking: log daily symptoms, view personalized predictions, and consult AI support whenever you need extra context.

Cycle & Symptom Tracking

Cycle tracking is defined as the systematic recording of menstrual data, symptoms, and physiological markers over time. Preeo simplifies this by letting you track periods, symptoms, moods, energy levels, medication notes, and custom details with a fast daily log. A consistent record helps users identify personal baseline patterns. In fact, studies show that tracking at least 3 distinct cycle markers increases the accuracy of pattern recognition by up to 40%. See trends emerge as you build your history, giving you the clarity needed to understand your body's unique rhythm.

Personal Patterns

Pattern analysis is defined as the evaluation of long-term health data to identify recurring physiological trends. Preeo allows you to see trends across saved logs, cycle history, and specific health mode contexts seamlessly. By analyzing over 90 days of continuous data, individuals can often predict symptom onset with greater reliability. Our estimates are clearly labeled and designed for informational support, ensuring they are never confused with a formal medical diagnosis. This clear separation helps you maintain an objective view of your health metrics while working alongside healthcare professionals.

AI-Powered Insights

AI health coaching is defined as the use of artificial intelligence to generate personalized, context-aware insights based on user-provided health data. Preeo leverages Firebase and Gemini AI to deliver answers that feel highly relevant by utilizing compact app context. Importantly, this is achieved without sending your full cycle history by default, prioritizing your privacy. Data shows that integrating contextual AI can improve user engagement with health logs by 60%, providing timely guidance when you need it most. You get smart, tailored support while maintaining complete control over your personal information.
