WHY WOMEN CHOOSE 28
Most fitness and diet apps assume every day is the same. Your body doesn't work that way. 28 uses cycle-based wellness to help you train, eat and feel your best all month.
28 is for general wellness and fitness. It is not a medical device and is not intended to diagnose, treat or prevent any condition, or to be used as contraception. Fertile window estimates should not be used to prevent pregnancy. Talk to a healthcare professional about medical concerns.
SUBSCRIPTION
28 offers optional auto-renewing subscriptions to unlock full features. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple ID account settings.
