The Mission: Closing the Gap in Women’s Health Women’s health is severely understudied. When information does exist, it is oftentimes largely inaccessible, making it difficult for women to stay well-informed about their bodies.

As college women, we are over-scheduled and under-rested. While most tracking applications rely on routine to predict and advise, we wanted to build something that understands that every day looks different.

Introducing: Big Sister Big Sister is the first all-in-one health ecosystem that treats your cycle, lifestyle habits, and hormonal symptoms as part of the same story.

Why We’re Different While other apps exist to track cycles or hormones, they are often:

Pink Taxed: Hidden behind a paywall.

Rigid: Expecting a fixed routine for predictability.

Uninspired: Simply boring to use.

Our Solution Big Sister understands that college life means constant change. We’ve designed a quick, easy-to-understand, women-focused tool that fits into your actual daily life.

Key Features Integrated Tracking: Monitor your cycle, sleep, caffeine intake, mood, and more for an in-depth view of your well-being.

Hormone Insights: Get extra clarity on fluctuations (supported by your lab test results).

Big-Sis AI Agent: An AI companion that provides actionable advice and realistic insight into why you might be feeling "off."
