Cylia: Period & Mood Tracker
Pregnancy & Ovulation Calendar
Only for iPhone
Free · In‑App Purchases
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, pregnancy tracker and mood journal in one place. You can see when your next period might start as a date range, follow the days you're more likely to get pregnant if you want to be a mom, or count the weeks if you're pregnant. And every day you write down 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
— Cycle ring: which day of your cycle you're on and what might come next, at a glance
— 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, your best days and your chance of pregnancy, day by day
— Pregnancy tracker: week by week and trimester, estimated due date, weight and symptoms
— Mood journal: joyful, sad, angry, anxious or grumpy; every entry becomes a memory on your shelf, put
away when the month ends
— 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, for your daily log and your 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
— Works offline; light and dark themes; English, Turkish, Spanish and German

PRIVACY
No account, no sign-up, no email. Your entries stay on your phone. If you turn on backup, your data is encrypted before it leaves your phone; the server can't read it, and neither can we. We don't sell your data.
Cylia is not a medical device and isn't meant for diagnosis or contraception. Estimates are approximate. If something worries you, your doctor is the best person to ask.
Subscriptions auto-renew at the listed price unless canceled at least 24 hours before the end of the current period. Payment is charged to your Apple ID at confirmation of purchase. You can manage or cancel your subscription anytime in your App Store settings.
