Period dates, symptoms, and notes are stored locally on your iPhone. We don't collect your cycle or symptom data. There is no cloud sync, Apple Health connection, or automatic sharing. Export a copy only when you choose. START WITH WHAT YOU KNOW Add a period with start and end dates, record an ongoing period, or come back to earlier dates. Edit a whole period without losing its symptoms or notes. Setup is optional: you don't need to rebuild years of history to begin. LOG YOUR WAY Record flow, cramps, mood, and notes on any day. Add custom symptoms, put favorites first, and leave anything blank. An unanswered field stays unanswered. SEE YOUR HISTORY CLEARLY Compare completed cycle lengths and period lengths, with the number of records behind each summary. Browse a dated timeline of symptoms and notes, filter entries, and return to a day to make a correction. YOUR RECORDS. YOUR CALL. Create a readable PDF report or CSV file right on your iPhone. Choose the dates, symptoms, and notes to include, preview the result, then decide whether to share. Export and deletion remain available after your trial ends. Add an optional app lock using Face ID, Touch ID, or your iPhone passcode. ESTIMATES ARE OPTIONAL Show or hide period estimates and choose whether to receive a period reminder. An estimated fertile window is available only if you turn it on. It does not confirm ovulation. Estimated fertile window based on cycle averages. Not a contraceptive. Not for family planning.
