Created by psychiatrist Omer Liran, MD, MSHS for his son Aiden

Made for curiosity. Room to grow.

PRACTICE WITH A PURPOSE

A story to follow.
A reason to try.

Math becomes part of the adventure, with a little encouragement at every step.

01

Step into a story

Choose a path with Pip and meet new friends. Each short chapter gives your child something meaningful to help with.

02

Make the numbers matter

Count, add, and solve a small puzzle to move the story forward. Gentle hints and read-aloud support are there when needed.

03

Bring home a little win

Collect stars and destination stickers. Every completed puzzle counts, including answers found with a helping hand.

A GALAXY THAT CAN GROW WITH THEM

Start where they are.

MEET THE CREATOR

A gentler place to practice.

I’m Omer Liran, MD, MSHS, a psychiatrist at Cedars-Sinai Medical Center. I made this game for my son, Aiden, who loves it, and I wanted to share it with your family.

If your child enjoys it or benefits from it, please drop me a note! I’ll keep Cosmic Quest completely free for as long as I can.

This is an educational app, not medical care or a clinical assessment.
