Charts that explain
Cycle length history, symptom load by day, cycle comparison, sleep against cramps and basal temperature, all drawn as crisp SVG.
Doctor visit prep
A checklist of what to bring and questions to ask, plus a clinical PDF with a verification code.
Gentle consistency
Streaks, milestone badges and a logging ring. Missing a day never deletes anything.
Private by default
No account, no ads, no analytics in the app. Optional sync is encrypted with a passphrase only you know.
Accessible
Keyboard friendly, screen-reader labels, high-contrast and reduced-motion options.
Your data never has to leave your phone
There is no database behind this website. Your entries live in your browser. You decide if you want an encrypted backup, AI help with your own key, or email reminders, and each of those is off until you turn it on.
“Predictions are estimates. The app is a companion for your own awareness, not a replacement for your doctor.”
