iPhone
Luna is a period and ovulation calendar that tells you when your period is due, which phase of your cycle you are in and what will feel good today. No account to create, and your data stays on your iPhone.
IS MY DATA SAFE?
It stays with you.
• Everything is calculated on your iPhone. You do not need to create an account.
• Face ID lock.
• Chat with Luna uses Apple Intelligence and runs on your phone (on compatible iPhones).
• Only what you choose to share with your partner leaves your iPhone, plus your Luna Plus purchases, which RevenueCat checks with Apple.
WHEN IS MY PERIOD DUE?
• A forecast of your next period as a range of days that gets sharper with every cycle you log.
• A reminder two days before your next period, so you can restock or pack what you need.
• See when your period is late or your cycle is out of its usual pattern.
• What you tend to feel tomorrow, so it does not catch you off guard.
• Log your flow, symptoms, emotion, cravings and notes in two taps.
WHAT ARE MY FERTILE DAYS?
• Ovulation and fertile window, day by day.
• Log your ovulation tests and Luna adjusts the forecast.
• Reads your Apple Watch wrist temperature from the Health app.
WHAT WILL FEEL GOOD TODAY?
Luna does more than count days: it is with you through every phase.
• Water, sleep, movement and food tips based on your phase and what you log.
• 10, 30 or 60 minute plans depending on how you feel.
• Today's menu: breakfast, lunch, snack and dinner recipes that match your cravings and symptoms (Luna Plus).
• Guided movement sessions, gentle, moderate or intense, to match your energy (Luna Plus).
WHAT ABOUT MY PARTNER?
• Invite your partner and choose what they see: your emotion of the day, your symptoms or both.
• A widget and notifications on their iPhone.
• They can send you a caring gesture with one tap.
BIRTH CONTROL REMINDERS
• Pill, mini-pill, ring, patch or IUD: Luna reminds you at your time.
• Mark it as done from the notification or the widget, without opening the app.
FOR YOUR APPOINTMENT
• Your cycle in numbers: average length, variation and patterns with your sleep and exercise.
• A PDF report of your latest cycles to take to your doctor (Luna Plus).
WHO LUNA IS FOR
For anyone who wants to know when their period is due, understand their phases and look after themselves every day. Luna does not track pregnancy.
LUNA PLUS
Unlocks Nutrition, Movement and the doctor report. When you finish setting up, you start with a 7-day free trial of the monthly plan if you have never subscribed, or make a one-time lifetime purchase. If you cancel the trial, you keep using your period log, the calendar, the forecast, fertile days, Emotions, Chat with Luna, reminders and partner sharing for free.
The monthly subscription renews automatically unless you cancel at least 24 hours before the end of the period. You can manage and cancel it in Settings > your name > Subscriptions.
MEDICAL DISCLAIMER
Luna is a tracking tool. It is not a method of contraception and does not replace a doctor.
