## What is LunaCat?

From your period to ovulation and trying to conceive — your body's rhythm, at a glance

Your body shifts a little every month. Track it with LunaCat.

LunaCat is a free period tracker that logs your cycle, ovulation and fertile window, and helps with trying to conceive and looking after your health.

Log just your period start date and it works out your next period, your predicted ovulation and your fertile window. You can log the day-to-day too — symptoms, mood, discharge, birth control pills.

No account needed. Start light, with a calendar that's just yours.

■ Logging a period is one tap

When your period starts, press the button. The start date alone is enough to work out your next cycle.

· One-tap period start
· Next period worked out for you
· See your cycle and period length
· Edit past periods
· Month and year calendar views

■ Period, ovulation and fertile days on one calendar

Days you bled, your next expected period, predicted ovulation and your fertile window are each marked clearly. Tap a date and that day's logs open right up.

■ Ovulation and your fertile window

Log a positive ovulation test and this cycle's prediction adjusts to it. Not using test strips? You can mark your ovulation day yourself.

· See your predicted ovulation
· See your fertile window
· Log positive ovulation tests
· Mark ovulation yourself
· Cycle view built for conceiving

■ Trying to conceive, pregnant, breastfeeding or on birth control

Your home screen follows whatever matters to you right now. Trying to conceive? It leads with ovulation and your fertile window. Just tracking your cycle? It leads with your next period.

You can also say you're pregnant, breastfeeding or on contraception.

■ Log how your body feels

Dates alone tell you less than dates plus how you actually felt.

· Period symptoms and PMS
· Mood changes
· Vaginal discharge
· Digestion and activity
· Sex
· Contraception
· Birth control pills

Look back at how you felt at this point in earlier cycles, too. Log your mood and Luna the cat's expression changes with it. Pick who keeps you company — Luna the black cat, or Pinkduck.

■ Your cycle, analysed

Once a few cycles are logged, your own pattern gets easier to read.

· Average cycle length
· Average period length
· Cycle changes month by month
· How regular your cycle is
· Symptom heatmap

See which symptoms and moods tend to show up at which point in your cycle.

■ Only the reminders you want, when you want them

· Next period reminder
· Ovulation and fertile window reminder
· Birth control pill reminder
· Daily log reminder

■ A home screen widget

See how many days until your next period without opening the app. Because it's personal, the details are hidden by default — turn them on whenever you like.

■ Share only what you want with your partner

Turn your fertile window and predicted ovulation into a card and send it to your partner. Choose exactly what goes on it — ovulation date, fertile window, your moods and symptoms. The card is built on your own device.

■ Reads that make sense of your body

· The menstrual cycle in four phases
· Premenstrual changes (PMS)
· Choosing period products
· Birth control methods
· Vaginal health
· Signs worth seeing a doctor about

■ Your logs, for your eyes

Period, pregnancy and sex logs are sensitive, so privacy got real attention.

· App lock with Face ID or your fingerprint
· Screenshot and screen-recording blocking
· Hidden notification content on your lock screen

LunaCat is not a medical device, and period, ovulation and fertile window predictions are for guidance only. Fertile window predictions must not be used as a method of contraception. Talk to a healthcare professional about any medical decision relating to your health or a pregnancy.
