iPhone
Period calendar, pregnancy tracker and mood journal in one app. Your cycle at a glance; your notes, photos and memories on your phone.
Your cycle, your notes, your memories. All on your phone.
Cylia keeps your period calendar, ovulation tracker, pregnancy tracker and mood journal in one place. You can see when your next period might start as a date range, follow your likely ovulation and best days if you want to be a mom, or watch your baby grow week by week if you're pregnant. And every day you log how you feel becomes a memory.
WHAT'S IN CYLIA
— Period calendar: your next period is estimated as a date range, based on your own cycles
— Today: which day of your cycle you're on, which phase you're in and what it may bring
— Period tracking: the days it starts, continues and ends; flow, symptoms and a note on one screen
— I want to be a mom: likely ovulation and your best days; log LH tests, morning temperature (BBT), cervical mucus, sex and pregnancy tests
— Pregnancy tracker: your baby's development week by week, trimester, estimated due date, weight and symptoms
— Pregnancy tools: kick counter, birth prep lists, appointments and reminders
— Mood journal: joyful, sad, angry, anxious or grumpy; every mood drops into the month's sphere and shows how your month felt
— Discover: short cards, quizzes and true-or-false questions on periods, ovulation and pregnancy, all with sources
— Insights: your period, cycle and pregnancy summary on one screen
— Memories: add a note and photos to a day, then tap any day to read it again
— Reminders: before your period, on your best days, before ovulation, for your daily log, morning temperature and pregnancy week; each one on or off, at a time you choose
— PIN and Face ID lock; notifications show discreet text on the lock screen
