Sunja: Interactive 3D Science

Step into worlds, ask anything

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Faster worlds, steadier on every device, and easier to read at any text size. 22 interactive worlds to explore, and a tutor you can ask anything. Sunja is interactive 3D science for anyone who never stopped asking why. Every concept is a small 3D world you can step into. Split a beam of light into colour. Watch pollination happen. Follow how GPS works out where you are. Beside every world there is a reading guide that tells the story in plain language, and audio narration for when you would rather listen. When a question comes up, ask Sunja, the built-in tutor, by voice or by typing. WHAT IS INSIDE • 22 interactive 3D worlds across nature, technology, space and history • A reading guide for every concept, written to be clear rather than clever • Audio narration you can play anywhere • Ask Sunja — a tutor for follow-up questions, by voice or by text • Bookmarks for anything worth coming back to • Streaks and XP that quietly count the days you show up FOR CURIOUS PEOPLE OF ANY AGE Sunja is built for curiosity at any age: safe and comfortable for children, and still interesting for grown-ups. Choose a kid, teen or adult profile at the start and the explanations follow. TOPICS Photosynthesis, germination, pollination, the human heart, DNA, cell division, light and colour, magnetism, gravity and orbits, moon phases, the life of a star, plate tectonics, the water cycle, the periodic table, chemical bonds, binary code, the internet, GPS, ancient Egypt, the Renaissance, the Industrial Revolution — with more worlds added over time. HONEST ABOUT LEARNING No IQ promises. Better inputs: active exploration, retrieval, and spaced curiosity. Small lessons compound. FREE TO START Sunja is free to start: explore the worlds, read the guides, listen to the narration. Sunja Pro unlocks every world, every reading guide and every tutor session, monthly or annually. A subscription renews automatically unless you turn it off at least 24 hours before the period ends; you can manage it in your account settings at any time. Learn something worth remembering.
