A letter from Sosô's parents
This is how Sosô came to be
Verônica & Rômulo
Hi, we're Rômulo and Verônica.
It started two years before her first period.
Soso didn't start the day our daughter Sophia (we've called her Sosô since she was little) got her first period. It started two years earlier, when she was 8, and we began noticing small changes in her body.
That felt early to us, so we took her to see her doctor. The doctor confirmed it: her first period was coming sooner than most parents expect. Girls getting their first period before 11 or 12 is becoming more common. We weren't outliers. A lot of families are quietly going through the same thing.
The next two years were homework.
Our work started right there. We spent the next two years reading, learning, and figuring things out. Why was this happening earlier than expected? What did she need to know? How do you talk to an 8-year-old about her body in a way that's honest, calm, and not scary?
We did the work. We talked to her. And we tried to get her ready for the day.
When the day came.
She had just turned 10. It wasn't a surprise. She knew what was happening. We knew what was happening. And we just kept moving along.
She was the first of all her friends to get her period. None of them had been through this yet, so she had no one her own age to talk to about it. That part was a little lonely. So we became the people she could talk to, ask questions, and complain to.
Then she asked for an app.
Sosô has been doing ballet since she was little. She's used to paying attention to her body, how it feels and what it can do. A few weeks after her first period, she asked for an app to track her cycle.
The first app we tried was the one Verônica uses. Within minutes we realized it was completely wrong for a 10-year-old: pregnancy tracking and a lot of other grown-up topics. So we kept looking, but the apps that claimed to be for kids still had the same adult content.
So we built one.
Soso is the app we wished existed back then. It's a period tracker for kids and young girls, built around health and education instead of pregnancy and adult relationships.
It explains what a period is, why it happens, what symptoms to expect, and how to feel a little less alone.
The character who guides everything inside the app is named Sosô, after our daughter, because the whole thing started with her.
A small family team.
Rômulo handles the building side. Verônica handles the words, the tone, and what matters most when a young girl goes through this for the first time. Sosô herself is our toughest reviewer, with very strong opinions about what stays in.
