Painful Periods Are Common — You Shouldn't Have To Guess

Many women find cycle symptoms affect their daily lives. 28's functional nutrition and phase-specific movement are designed to support hormonal health across every phase of your cycle.

Workout With Your Cycle, Not Against It

Many popular fitness methods were designed for men, not women, with no regard for the menstrual cycle. 28 is the first method of its kind designed to optimize your energy, hormones, strength, and flexibility as you experience changes throughout your cycle.

You Deserve More Than A Period Tracker

Your cycle has four phases. Each phase brings changes to the brain and body. Exercising and eating based on your cycle means changing the types of movements and nutrients during each phase to optimize your physique, hormones, and mood. 28 empowers you with simplified science, breathtaking content, and cutting-edge technology.

Become the Expert of You

You are a mystery. Your body doesn’t have to be. We’ve been locked in the passenger seats of our own bodies for far too long. School taught us little-to-nothing about how our cycles and hormones actually work. 28 empowers you to connect with your body by understanding the beautifully complex nature of your biology, one day at a time.

User Privacy Is Our #1 Priority

Many women have valid concerns regarding the privacy and safety of their personal health data. We're proud to have one of the strongest privacy policies in all of tech, which includes a steadfast commitment to never sell user cycle data to anyone for any reason and to never turn over user cycle data to any government or regulatory authority under any circumstance. Our algorithm stays manually controlled by you, not driven by invasive machine learning. The only cycle data we currently collect is provided voluntarily by the user. It is strictly confidential and used only to provide a customized experience. Any cycle data the user provides now or in the future can be changed or deleted by the user at any time. We do not store deleted cycle data. Once the user deletes that information, it is gone forever.
