Period and fertile-window forecasts grounded in real cycle science — and they get sharper as you log.
BBT charting with thermal-shift confirmation, ovulation tests, and a two-week-wait countdown.

Pattern-aware nudges, birth-control reminders, and fertile-window pings — as playful or discreet as you like.
Your cycle day and phase at a glance on your Home Screen, Lock Screen, and Apple Watch.
No account, no analytics, no third parties. Lock the app with Face ID and export your data anytime.
Your data never leaves your phone unless you choose to share with a partner — and even then it's end-to-end encrypted by Apple. We have no servers and never see your data.
Current phase, cycle day, and a gentle heads-up for what's ahead.
Flow, symptoms, mood, discharge, BBT and ovulation tests — tap what fits.
A color-coded calendar of your past and predicted phases.
Averages, prediction confidence, and what your body tends to do.
They see your phase and countdown — never your symptoms or notes.
