As parents ourselves, we wanted to build a kids’ learning app we could feel truly good about. One that feels calm, beautifully designed, and genuinely helpful. kukumber blends interactive math games with purposeful feedback to keep kids engaged without overstimulation. It supports daily math routines, skill-building, and confidence—all with a clear, distraction-free interface. This is only the beginning! More topic-based lessons, fun math mini-games, and adaptive learning paths are coming soon. Best, Olena, Founder of kukumber.kids

Anything educational has my support. What other educational areas do you want to cover?

Elena Avramenko

@busmark_w_nika thank you Nika! In the future we are going to cover also everything around creativity, in other apps which are launching later this summer. Because we believe Math + Creativity is essential future skills for kids

Elena Avramenko

@busmark_w_nika thank you! Education for kids is such a positive place to be as we build our own future. In the next years I believe the most important skills kids needs to learn is STEM + Creativity. For STEM - we will be covering Math with kukumber, but also we are cooking right now a bunch of creativity apps for kids! First releases this summer!

Nika

@lenaavramenko Math is crucial – I can see how this subject is going down in many students, we need more solutions that encourage them to learn math + creativity (I like this one more than Math tbh :D)

Great app do you plan to release on Android?

It reminds me of my Multiplication Kingdom app.

Elena Avramenko

@sandochee Yes, we love to build Android and the whole family of apps! Will check what you mentioned. The more great product we have - the better for kids.
In kids EDU market I think that all players who make quality products - create value and variety. As learning need variety, same as you read multiple books - you have a pallett of apps.

Linda Mwangi

This sounds like a thoughtful learning tool! How does the AI mascot engage kids differently than traditional methods? 🧒💡

Elena Avramenko

@linda_mwangi thank you! yes, indeed it took us a year to build and test it before today!
Unlike traditional drill apps, our AI mascot explains new concepts, helps when the child struggles, and reacts to their progress — making math practice much more personal and motivating. We see that kids stay engaged and actually ask to do more!

Charles Binet

Great job to the team! It looks very playful and we need waaay more educational products on the phone for kids. Well done for taking a stand 👏

Elena Avramenko

@charles_binet Thank you! Fully agree - kids products market should have more great products - from education and aestetical aspects!

Scott Kennedy

This is so incredible cool, and badly needed. I had the pleasure of being part of the early beta, and I am very impressed with what this team accomplished! With all the crappy AI tools flooding the market these days, it's great to see something that actually leverages the power of AI to help humanity grow and learn.

Elena Avramenko

@scott_kennedy thank so much for your kind words! your support means a lot!

The design of kukumber is absolutely adorable! I love it so much, and I'm sure kids will fall in love with kukumber too!

Elena Avramenko

@hi_caicai thank you! we believe kids deserve a top UI/UX and should build a design taske from an early age!

🚀 Pierre-Henry 💡

So good. Math is my jam! (no matter if we are kids or not).

Elena Avramenko

@phenrysay I love how you said this - "Math is my jam"! will steal this wondeful quote!

Germán Merlo

Yeah! Excatyl what I'm looking for to my son. Happy to see you helping on this. All the best here Elena!

Elena Avramenko

@german_merlo1 oh, thank you so much for your kind words!
if you'd like to be part of Parent Ambassadors group - just let me know, they have forever free access to app and test all things fist!

Zagita

Okay, this is adorable—that little animated logo alone makes me wish I could redo my math childhood! 😍 As a former ‘I hate math’ kid, I can already tell this would’ve saved me years of frustration. The calm, playful vibe is perfect for tiny learners. Any plans for an Android version or multilingual support soon? (Asking for my niece who’s currently inheriting my math trauma 😂)

Elena Avramenko

@rani_zagita thank you for your support! as a bootstrapped company who wants to stay this way we needed to start with one - so we selected iOs, Android will come next year and also desktop! Step by step!
iOs app currently localized for 12 languages!

Damian Skotzke

Built by passionate parents and builders! Fingers crossed for the next steps. It's a great mission 💙

Stanislav Govorukhin

Really impressed with kukumber so far. Short daily lessons are the perfect sweet spot for kids. As a designer, I think the app looks and works amazing. Joyful UI instead of fluid glass! :D

Would love to see new games and challenges in the future! 🙌

Elena Avramenko

@stanislav_govorukhin1 haha, no fluid glass for sure!

Niamh G

What a brilliant way to give kids a love of maths rather than a fear. Cheers!

Elena Avramenko

@ngorina indeed! thank you for the support!
