It’s time we expect more from our cycle trackers.
Did you know polycystic ovary syndrome (PCOS), a leading cause of infertility, is considered one of the most common endocrine disorders in women, although up to 70% of cases go undiagnosed? Or that endometriosis affects roughly 1 in 10 individuals but currently takes an average of 7 to 8 years to be diagnosed? Let’s start listening to what our bodies are telling us.
Sara helps you better understand and manage your unique cycle so you can have more informed conversations with your doctor, uncover patterns and risk of breast cancer, endometriosis, and other conditions, and start feeling your best—no matter where you are in your cycle.
Our Work at Comma
At Comma, we believe managing your period shouldn't compromise your health, your privacy, or your potential. You deserve to demystify your body so you can make empowered choices. This is why we built Sara, the only HIPAA-informed cycle tracking platform. Sara helps college students like you better understand yourself and your body by uncovering patterns in your cycle, predicting menstruation and ovulation, monitoring PCOS symptoms, and more.
What Makes Sara Different
Some period tracking apps make promises they can’t keep. Others do less when what you really need is more. University life is busy—and you should have a cycle partner you can count on.

Sara Is a PWA
Period apps can be super helpful as a college student, but the data they collect are deeply personal. We’re talking health info, moods, sex lives, stress levels. For university students especially, knowing where your data go (and who can access them) really matters. Progressive web apps (PWA) offer strong privacy protections, meaning your body data won’t be sold, shared, or used against you—now or later.
There’s Power in Progress
At Comma, we are always improving. It’s our goal to be constantly innovating and pioneering new technology, materials, and services to make menstrual care better. Sara is just the beginning. We’re building Comma for you and with you.
