About this app

We built Soso as parents. Soso is designed to be your (or your daughter's) first period tracker.

A place to learn, observe, and build awareness over time, without pressure, noise, or adult-focused content. It’s made to feel safe, clear, and supportive, both for kids using it and for parents guiding them.

When our daughter started asking questions about her body changes, what we found were apps made for adults, with content, language, and features that didn’t feel right for a first experience.

So we decided to build something different.

What Soso helps with:
- Soso focuses on understanding and learning first, then tracking comes naturally.
- Learn about cycle changes with clear, age-appropriate explanations
- Build the habit of noticing and logging periods
- Reduce anxiety by providing information at your pace
- Create space for conversations between parents and kids


Visual cycle tracking
- Log periods with simple taps
- Visual cues and colors to reflect flow intensity
- Clear calendar view to see cycles over time
- Easy access to past logs and history


Daily guidance, gently
- Smart daily check-ins during a period
- Helpful prompts that guide without forcing answers
- No pressure to log everything perfectly
- The app adapts over time as more data is added


Mood & symptoms
- Optional mood and symptom logging
- Simple icons and language
- Encourages self-reflection without judgment
- Helps connect how the body feels over time


Built for families

- Designed by parents, for parents
- No social feeds or chats
- No adult content
- Private by design


Soso is not about comparison, performance, or social interaction. It’s about understanding your own body, at your own rhythm.


A calm place to start
Whether you’re just beginning to learn about cycles or building confidence over time, Soso is here to support that journey with care. We’re building Soso thoughtfully, one step at a time, and we’re glad you’re here with us.

Ratings and reviews

this is a great app all the other period tracking apps have a age restriction even though girls can get there period pretty young i have only been using this app for a bit but I can already tell it is great!

It's a very cute and amazing app I'm young myself and it's very good and I love it so much.

I like it and it's so cute omggggg!!!!!!!

What’s new

Not everyone can get a subscription. I know. So now you don't need one: meet Drops. One Drop logs one period, and the whole app is yours. No subscription, nothing monthly.

They're starting at a much lower price than they'll normally be, so if a subscription was the thing standing in your way, this is your moment. Also, they're not "Drops" in every language. Each one got its own word, picked to sound natural there.
