Sunja vs Quantum Lab

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.

Stop reading about quantum physics. Start touching it. Quantum Lab teaches quantum mechanics through 21 interactive experiments you operate with your own hands — the double slit, Schrodinger's cat, entanglement and more. No equations required. You change a condition, you watch what happens, you understand why. ■ A four-step loop — one idea in three minutes 1. Concept card — one analogy to get the intuition 2. Experiment — change the setup yourself 3. Quiz — check what you just understood 4. Next up — the app points you to the experiment that builds on it You never have to wonder what to do next. ■ 21 interactive experiments (all free) · Quantum pack (16) — Schrodinger's cat, double slit, photoelectric effect, energy levels, polarization, quantum coin, Mach-Zehnder interferometer, decoherence, spin measurement, quantum tunneling, the uncertainty principle, entanglement, Stern-Gerlach, quantum eraser, the quantum Zeno effect, Bell test · Solar system pack (5) — sun scale comparison, orbit dragging, gravity well, moon phases, comet orbits ■ A 12-rung concept ladder Superposition, wave-particle duality, the photon, energy quantization, spin, polarization, the qubit, tunneling, uncertainty, entanglement, interference, decoherence. Each rung is placed so the one above it only makes sense once you have stood on the one below. ■ 115-entry glossary Every term you meet is one tap away, any time during a lesson. ■ Three languages Korean, English, Japanese — switchable at any time in Settings. ■ For parents and teachers · No in-app purchases. Nothing at all is for sale, so no accidental spending. · No account, no sign-up, no login. We never ask for a name, email, phone number, location or photos. · Learning progress stays on the device and is never transmitted. · Ads are bottom banners only. No full-screen interstitials, no rewarded ads, and no ads at all while you are operating an experiment. · Non-personalized ads only — no interest-based targeting. · Every learning feature works fully offline.
