Features & Capabilities

One app for periods, hormones, body changes, random questions and the “why am I like this today?” moments. Explore for free. Unlock full access with Body OS Membership.

The user manual your body forgot to come with.

Body OS helps make periods, hormones, puberty, body changes and the “wait… what is my body doing?” moments make a lot more sense.

We take the complicated health “what’s wrong with me?!” terminology and translate it into relatable, real explanations and experiences that make you go: “Ohh. That makes SO much sense.”

Think of your body like a phone: (Growing up is a BIG software update.)

• You (yes, you) are the phone. • Hormones are your notifications. • Your cycle phases are different phone modes. • Different parts of your body are different apps.

No “eww”. No awkward whispering. Just what’s actually going on, in a way you can actually understand.

Explore Body OS for free, for as long as you like. Unlock the full experience with an optional Body OS Membership.

BODY OS FREE INCLUDES:

• Hormone HQ • Girls’ Glossary • Body App Store and body app summaries • Cycle Calendar logging • Cycle Cheat Sheet • Selected Things You Secretly Google collection • General Body Settings

Body OS Free is not a time-limited trial. It is the permanent free version of the app and does not automatically convert into a paid membership.

  1. Periods

Prices are localised by Apple through the App Store and may vary by country or region. The current price for your storefront will be displayed before you confirm your purchase.

Payment will be charged to your Apple ID when your purchase is confirmed. Your subscription automatically renews for the same subscription period unless it is cancelled at least 24 hours before the end of the current period.

Your account will be charged for renewal within 24 hours before the end of the current subscription period. You can manage or cancel your subscription through your Apple ID subscription settings.

DETAILS:

• Body OS is educational, not diagnostic. • It does not tell you that something is definitely wrong with you. • It does not pretend everyone has the same cycle. • It does not generate medical answers. • Your Cycle Calendar data stays on your device. • There is no public profile, no social feed and no requirement to share your personal cycle data with REREIN.

Because understanding your body should feel less like sitting through a biology lesson and more like finally finding the settings menu.
