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!

Over this weekend, this app seems to have taken a nosedive. I can't login, it has a "dev" red label on it. I've been using it a lot and all of a sudden I'm just stuck in a loop of sign in, verify, denied, sign in, verify, deny. Hoping for an update to fix this is underway. have loved the app, disappointed about it not working for sure.

If you're like me, you don't log your period the day it starts; and if you want to edit your period dates on the 28 app calendar, good luck. All you've logged sp far is now erased, you have to start over and then enjoy a very touchy, un-intuitive calendar. If you manage to get even one period properly logged, kudos. If you can get the app to accurately predict your cycle, you're some kind of wizard.

This app was made for WOMEN!!! SUCH A BREATH OF FRESH AIR! A period app that focuses on women exclusively was desperately needed. Let's all balance our hormones & have healthy periods!!! On a side note, I think the images of the women are absolutely beautiful. I don't understand why so many women have issues with it, but I guess my self-esteem isn't low
