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, and it was going to happen sooner than most parents expect. But she also told us something that made the whole thing easier to sit with. Girls getting their first period before 11 or 12 is becoming more and more common. We weren't outliers. A lot of families are quietly going through the same thing.

Girls getting their first period before 11 or 12 is becoming more and more common. We weren't alone in this.

The next two years were homework.

So 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 actually 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.

But there was one part we didn't fully see coming. 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 stepped in as the people she could talk to, ask questions, and complain to when she felt like complaining.

She was the first of all her friends. That part was a little lonely.

Then she asked for an app.

Sosô has been doing ballet since she was little, and she's still very dedicated to it. She's used to paying close attention to her body, how it feels, what it can do on a given day. So a few weeks after her first period, she asked us for an app to track her cycle.

The first thing we tried was the app Verônica uses. Same idea, just for her, right? Within a few minutes we realized it was completely wrong for a 10-year-old. Pregnancy tracking, sex logs, adult relationship content. Not for a kid.

So we kept looking. We found a couple of apps that claimed to be made for kids, but when we actually opened them, they weren't. Same adult content, slightly different paint job.

There was simply no app for a young girl who had just gotten her first period.

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 in the middle of it all.

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 (he's spent his career working on apps). Verônica handles the words, the tone, and the things that matter most when a young girl is going through this for the first time. Sosô herself is our toughest reviewer, and she has very strong opinions about what stays in.

If this is your story too.

We made Soso for our daughter. We're sharing it with the world because a lot of girls and a lot of parents are in the same spot we were, sometimes earlier than they expected, looking for something safe, kind, and age-appropriate.

If that's you, you can download Soso for iPhone or Android. We hope it helps.

With love,

Rômulo and Verônica

Sosô's parents
