Read full description

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.

Quantum Physics: Visual Lab is a beginner-friendly way to explore the strange and fascinating world of atoms, photons, electrons, and quantum behavior. Learn step by step with short lessons written in plain language. Build your understanding of wave-particle duality, the double-slit experiment, superposition, observation and measurement, entanglement, uncertainty, tunneling, qubits, photons, orbitals, quantum fields, and modern quantum technology. Open the Visual Lab to see abstract ideas in motion. Watch interference patterns form, compare particle and wave behavior, explore superposition, adjust uncertainty, observe tunneling probabilities, investigate entanglement, and visualize a qubit. Check your understanding with lesson-based quizzes and a daily quantum question. Review explanations after each answer, track your quiz accuracy, complete lessons, keep a study streak, and earn achievement badges as you progress. Use the glossary to look up key terms quickly, then visit the scientist timeline to learn about the people who shaped quantum physics, including Planck, Einstein, Bohr, Heisenberg, Schrodinger, Dirac, Feynman, and more. Features: - 18 beginner-focused quantum physics lessons - 7 interactive visual simulations - 110 quiz questions with explanations - Daily quantum question - Progress tracking, quiz accuracy, streaks, and achievements - Glossary of key quantum terms - Scientist timeline with short biographies - Plain-language examples, formulas, misconceptions, and real-world applications - Optional lifetime unlock to remove ads and open all premium content Quantum physics can feel mysterious, but it does not have to feel unreachable. Visual Lab turns difficult ideas into clear explanations and interactive moments you can explore at your own pace. Educational note: This app is designed for beginner learning and intentionally simplifies some advanced physics concepts.
