Our Story

Why we built Soso

Soso started two years before our daughter's first period. She was 8 when we noticed the first changes in her body — and we couldn't find anything made for that.

So we built it.

🌸 A Gentle and Empowering App for Young Girls (and Parents)

This app is such a beautiful idea. Created by parents together with their teenage daughter, it truly understands what young girls need when they’re just starting their period journey. It helps girls track their cycles, understand their bodies, and learn what to expect — all in a way that feels safe, friendly, and age-appropriate. What I love most is how thoughtfully it addresses moods, body changes, and practical tips, including guidance on period products, without ever feeling overwhelming or uncomfortable. It’s exactly the kind of support I wish I had when I was that age. The option for parents to be involved is also a huge plus. It makes this app not only great for girls, but also incredibly helpful for parents who want to educate, support, and have better conversations with their daughters during puberty. A wonderful tool for young girls to feel informed, confident, and supported — and for parents to feel reassured that the information their children are getting is appropriate and empowering.

So helpful

This is the best period tracker ever for me and kid friendly. Soso also has a good quiz and this app asks how are you each day, as a person who hasn’t had their period this app is very helpful and I love it ever since I got this app!

UNBELIEVABLY AMAZING

Omg I am a teen and it is so good, it has humour and really gets the days right. Whoever created this is a miracle worker thank you so much and I will continue to use this app. This is perfect for teens and you have done such a great job!

PERFECT

Soso is a perfect app for younger teens first starting their periods or continuing and they want to know when it will start. It’s a hard subject to talk about but Soso isn’t talking about any weird topics. It’s only on what you should be doing (resting wise) or it will let you know if a doctor should be involved!!

It’s really good

I just got mine and I didn’t really know what to do or expect but this helps you track when to expect it and if something is not quite right.
