How are you going to track my first period if you don't know my age?

Okay, so the Soso app doesn't actually track your first period for you, like when it's going to happen. It's more about helping you track it after it starts and understand your body.1. We don't try to guess when your first period will be. No one can really know that for sure without checking you out, and even then it's just an estimate. What the app does is let you log when your period starts after it happens for the first time. Then, over time, as you keep logging, it can start to show you patterns in your cycle. Like when you usually get cramps or how long your period typically lasts. Fun fact: your age is actually pretty important for understanding puberty and period stuff, but doctors say there's a big age range for first periods, so knowing just your age isn't enough to predict it. And we literally never ask for your age anyway because that's super private. The app is designed for girls getting their first period, so it just assumes you're in that age group. And it's super private, by the way. No social stuff, no ads, no sharing your data. It's just for you to learn about your body. If you want to get an idea of how close you might be to your first period, there's a quiz on this site that helps you look at other signs your body is making: how close is my first period?
