Sunja vs Newtonic

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.

Newtonic turns 59 physics topics into simulations you can push around. Throw a ball and watch the range change with the angle. Swing a double pendulum into chaos. Bend light around a galaxy. Fire an electron at a barrier and watch part of it tunnel through. Every topic comes three ways: • Simulate: change real quantities, in real units, and watch the system answer. Every readout is computed from the actual equations. • Learn: the formulas with every symbol explained, a short plain-language explanation, the key ideas and guided experiments to try. • Quiz: a few questions with explanations, so you know what you understood before the exam does. Earn XP as you explore, read and take quizzes, keep a daily streak and collect 19 badges along the way. Tell Newtonic your level and favorite fields, and Home suggests what to try next. 59 simulations across 11 fields: classical mechanics, gravity and orbits, fluids, oscillations, waves and sound, thermodynamics, electricity and magnetism, optics and light, relativity, quantum mechanics, and atomic and nuclear physics. Made for high school and university students, whether you're studying for an exam or meeting physics for the first time. Works offline. No account, no ads, no tracking. On iPad, the controls sit beside the simulation and every field is one tap away. Free and Pro 18 simulations are free forever, at least one in every field. Newtonic Pro unlocks all of them, plus every new simulation as it arrives: • Yearly, with a one-week free trial • Monthly • Lifetime, a single purchase Payment is charged to your Apple Account when you confirm the purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period, and your account is charged for the renewal within the 24 hours before the period ends. You can manage or cancel subscriptions in your Apple Account settings. Any unused part of a free trial ends when you buy a subscription. Newtonic Pro can be shared with up to five family members through Family Sharing.
