Having your period is a lot to manage, but there's no need to be surprised! Luna is a period tracker built just for teens and anyone starting out their period.

Did you know that periods work differently when you are younger? Luna is custom built to predict periods with teen bodies in mind. You can use features like prep days and notifications to prepare yourself a couple days ahead so that you feel confident with your period. Luna also has optional password protection to help keep your information private.

Got questions about periods? We've got answers! The interactive learning section has all the information that teens and anyone just starting their period need to know. It will also help you get yourself ready even if you haven't started your period yet.

It's a good app for tween and up. it gives you information on various things related to a period, and it makes the experience pretty simple. The only downside is the "welcome to luna" message that pops up every time I open the app. If I misclick for something, it also pops up. overall, it's a great app, though. I would recommend it if you want a comfortable experience with periods.

probably one of the best teen period trackers out there. it tells you the basics, but doesn't get into deeper topics outside puberty. at first, I was using a different app, but it felt too mature for me. I then found this app through google, and I love it. so thanks to y'all for making girls feel better about themselves. ♡

this is the best app you can use for your period I just wish I could change the days apart cuz mine used to be 23 but now it's 18 days apart but so far this is the best period tracking app I have and I love how there are no ads! you can also decorate the wallpaper of it! then it also awnsers questions about puberty and if you need any more information it shows you an app that'll help! so far best period app!
