Most girls get their first period around age 10 — but nearly half feel completely unprepared, and most schools and pediatricians aren't filling the gap.

First Period does.

Built for girls ages 7 to their first period, First Period turns a moment that's usually feared and hidden into one she prepares for, understands, and owns.

MEET HER CARE TEAM

Three AI guides who grow up alongside her — and answer the questions she's too shy to ask out loud, by text or just by talking:
• Kai — her period-prep guide and bestie, right around her own age
• Olive — her food friend, making the best foods for her body actually taste good
• Seren — here for her heart, whenever she needs to talk

THE FIRST PERIOD PREDICTOR

First Period reads her body's signals to show a gentle window for when her period might arrive — never a scary countdown, never a hard date. So the first time isn't a surprise.

REAL PEOPLE, REAL TALK

A safe, scrollable feed of verified creators — girls her age, moms, and OB-GYNs — sharing honest period advice. Every clip is reviewed. No comments, no contact, no strangers.

HER BODY, DECODED

Every change of puberty explained like a superpower unlocking — celebratory and clear, never clinical or cold.

SAFE ENOUGH TO HAND HER

First Period was built by a board-certified reproductive-medicine expert with 20 years of clinical experience. If we can't make it safe, we don't build it:
• Private by default — no public profiles, no photo sharing, no kid comments anywhere
• COPPA-compliant — verified parental consent before any data is collected, and you control what's collected
• No ads, ever, and we never sell her data — it's hers, and she can delete it in two taps
• Gentle crisis detection that bridges to real human help, never replaces it

FOR THE GROWN-UPS WHO LOVE HER
Setup takes a few minutes alongside a parent. After that, she has a private, judgment-free place to learn — and you have peace of mind that it was built to earn your trust.
Her first introduction to her body shouldn't come from a search bar or a scared friend at recess. Start her journey with First Period.
