A period tracker that fits the way young cycles actually work, and looks the way you want it to.
Track
Log period days with a tap and Luna predicts what's next. Predictions are built for young cycles, which can be anywhere from about 20 to 45 days apart while they settle in, and they keep getting better as you log.
Get ready
Prep days show up before your period is expected, so you have time to pack a pad or pop some supplies in your bag. Turn on notifications and Luna sends a reminder that just says "Event tomorrow." Nobody looking over your shoulder will know what it's about.
Log your day
Tap a day to log how it went. Over time you'll learn the signs that your period is on its way.
Make it yours
Choose a photo background, a color, or a picture of your own. Decorate your calendar with stickers, and pick what shows on your home page.
Learn
Lessons cover first periods, supplies, cramps, hormones and more, including interactive diagrams of the reproductive system and the menstrual cycle. The Question Box answers real questions, sorted by topic.
Private
Luna has no ads and never sells your data. Lock the app with a passcode, and keep your notes to yourself, even from a linked parent.
Luna+
Luna+ is Luna's subscription. Sign in to back up your data, so it's safe if you lose your phone and ready on a new one. Luna+ also unlocks photo backgrounds and calendar stickers.
Family
A parent or guardian can link to your Luna with a short code, follow along with your cycle, and get a heads-up before your period so they can help.
Luna for parents
Track your period, get a heads-up before it starts, and learn how your body works.
