she.Calendar

Inspiration

We are women — and we’ve all experienced moments where we don’t understand our own reactions, energy levels, or emotions. Sometimes we can’t concentrate, can’t work out, or don’t feel social, and we end up blaming ourselves without realizing that our hormones are shifting in the background. Yet we still plan our routines, workouts, and social events as if our energy is the same every day. We wanted a simple way to see what our hormones are doing right now and get personalized tips, reassurance, and motivation. That’s why we created she.Calendar — to help women understand themselves better and plan life in harmony with their cycle, not against it.

What it does

she.Calendar analyzes the user’s current menstrual cycle phase and automatically adapts her schedule, lifestyle recommendations, productivity tips, supplement suggestions, workout intensity, and communication guidance — even giving her partner helpful insights to support her better.

How we built it

We built she.Calendar by integrating the Google Calendar API to read and adjust the user’s schedule in real time. Our React web interface provides a smooth and intuitive user experience, while our Python backend processes cycle data, applies phase-based logic, and connects to OpenAI to generate personalized tips, partner notifications, and lifestyle insights. Together, these components create a smart, cycle-aware calendar that adapts to each user’s hormonal rhythm.

Challenges we ran into

One of our biggest challenges was translating complex hormonal science into simple, supportive guidance that feels empowering rather than overwhelming. We also had to ensure the Google Calendar integration remained seamless and design an experience that adapts to each user without becoming intrusive. Balancing accuracy, personalization, and emotional sensitivity was a key part of the challenge.

Accomplishments that we're proud of

We’re proud that we turned a scientific concept into a warm, user-friendly tool that genuinely supports women in their daily lives. We built a functioning calendar integration, created meaningful partner guidance, and developed an AI system capable of generating personalized recommendations based on real cycle phases. Most importantly, we created something that can improve productivity, wellbeing, and relationships at the same time.

What we learned

We learned how deeply the cycle impacts daily life when you actually design around it — and how powerful technology becomes when it supports women’s wellbeing rather than expecting them to fit into rigid routines.

What's next for she.Calendar

Next, we plan to expand personalization with deeper AI predictions, symptom-based tracking, and advanced emotional-support features for partners. Our goal is to evolve she.Calendar into a holistic, intelligent wellness companion that understands the user’s cycle, anticipates needs, and supports both her body and her relationships.
