Log your period and Léa learns your rhythm to predict your next one, your fertile window and ovulation. Private, caring, no account.
The more you log, the more accurate Léa gets. Next period, ovulation, fertile days — all computed from your history, never a generic average.
Period, predicted period, fertile window and ovulation in soft gradients.
Flow, mood, symptoms, discharge, intimacy, water, weight, basal temperature.
Cycle length, regularity, frequent symptoms and fertility charts.
Upcoming period, fertile window, pill, daily check-in — at the right moment, kindly.
Your cycle day, phase and next period — up to a mini-calendar of the month.

Léa is built "local-first": your periods, symptoms and notes stay on your iPhone and your private iCloud. We sell nothing, we track no one. No account, no ads.
