To provide accessible, accurate, and private tools that help women understand their menstrual health, track their cycles, and make informed decisions about their bodies.

Who We Are

Period Calculator was founded with a simple goal: to make menstrual health tracking easy, accessible, and private for everyone. We believe that understanding your body is the first step toward better health and wellness.

Our team consists of healthcare professionals, developers, and advocates who are passionate about women's health. We combine medical knowledge with modern technology to create tools that are both useful and easy to use.
