No account needed. No data collected. Ever.
What is Bloom?
🌸
Built for girls aged 9–16. Not for adult women trying to get pregnant.
✨
No ads. No streaks. No shame. Just honest education.
Your cycle has four inner seasons.
❄️
Winter
MENSTRUAL
A time for rest and reflection. Your body is doing quiet, important work.

FOLLICULAR
Energy returns. Ideas come easily. This is your brave week.

OVULATORY
You're at your social peak. Words come easily, confidence is high.

Winding down. You might feel more sensitive — that's chemistry, not weakness.
