About this app

Get daily exercise videos, nutrition profiles, and emotional insights customized to your body’s natural cycle.

28 is the world’s first cycle-based fitness and wellness experience offering cycle tracking, transformative exercises, nutrition profiles, and science-backed emotional insights, all hyper-personalized to where you are in your natural cycle and controlled by you.

Designed by supermodel trainers and medical experts to work with your body’s physical and hormonal fluctuations. Powered by nature and innovative technology that personalizes your daily experience while keeping you in control of your cycle data.

Painful Periods Aren't Natural

But they are common. Synthetic estrogens in birth control, plastics, and beauty products have created hormone imbalances for millions of women. 28's functional nutrition was designed to naturally restore balance to your hormones, along with phase-specific functional movements.

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. We've intentionally built our algorithm to be manually controlled by the user at any time, as opposed to leveraging more invasive, machine learning methods. The only cycle data we currently collect is provided voluntarily by the user. It is also never shared with any existing or future investors. It is strictly confidential and used only for the purposes of providing a customized user 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.

Embrace your nature and begin today!

The free features seem great, and the premium even better, though I'll hold off on purchasing depending on the accuracy of the free features. HOWEVER - there HAS to be a more accessible viewing option that doesn't include the unceasingly moving background. And, in another realm of accessibility- I would love to share with my niece as this type of info is so helpful and especially having it in 1 place. BUT THE PICTURES. PLEASEEE include multiple body types, it's not a good message otherwise.

This app is pretty decent considering it's free (unless you want the premium version). It was recently updated, which I'm not a fan of. You used to be able to read all of the insights, but now it won't scroll down. Is that only available w/premium now? Also, when I play the workout videos, they no longer rotate to fill my screen when I go into landscape mode. This makes it hard to see it. 1 of the updates I actually enjoy are the suggested supplements (in the nutrition part) for the day/phase

As much as this app has provided a more seamless way of conducting my women's health from day to day, and there have major updates since I began using's stopped working on my phone. It's supposedly still compatible to my phone model and I have the current app version. It just stays frozen on the loading page. It's pretty much just taking up space on my phone now when it previously was so useful.
