About this app
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!
