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.

We will never sell your data or show you ads, and the app is always free!

Luna is the perfect app for tweens/teens and up! Its very easy to use as it teaches you about common questions asked by tweens without being to mature for them on the app. you can track it and gives you a 2 day warning for when it will come you can also put an optional password to keep others from opening the app. It has a small note book and you can change how long your periods lasts.

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.

I love this period app specifically because its free and you dont pay for a subscription unlike other period tracker apps, like im not paying to see when ill get my period. It can be a little inaccurate sometimes, ill get it a week before the app says sometimes but I only got it this year so it comes more randomly. good app I recommend because you shouldn't have to pay to see when you will start your period, right?
