AstrotouR vs Model Room

AstrotouR is an augmented reality observatory for iPhone. It brings the universe into your room using scientific imagery and visuals based on real physics. Explore the Solar System, the Milky Way galaxy, and its supermassive black hole, Sagittarius A*. Watch the Sun, planets, and their major moons, their internal structures, and surface features. Examine the cosmic phenomena from every possible angle. Learn about interesting facts and mythology of stellar bodies and their landscape. Enjoy the scenery around vehicles sent to Mars and the Moon. Take a moment away from the everyday hustle, become curious about the universe — and a little more thoughtful about our place in it. So far AstrotouR includes: • The Solar System: the Sun, its planets and moons, our home galaxy — The Milky Way, and the supermassive black hole in its center • Mars and lunar vehicles shown in their real environments • More than 300 articles and stories • More than 600 photos and images from historical and ongoing space missions • Detailed 3D visualizations, internal structures, and interactive points of interest • Support for light and dark mode, with dynamic text size based on your accessibility settings No data is collected. Your journey through the universe stays on your device.

Some shapes survive being drawn flat. Most of the interesting ones don't. Model Room brings 168 models across six galleries to your iPhone. Turn a mathematical surface, open a planet, compare organs or follow a moving machine. Each model comes with an explanation of what you are seeing—and why its shape matters. Nineteenth-century universities kept rooms of physical models because some things only make sense in three dimensions. This is a room you can carry with you. MATHEMATICS Explore 53 curves and surfaces. Space curves cast dotted shadows onto three coordinate walls, revealing how one shape becomes three different pictures. Move a point along a curve or across a surface and inspect its coordinates. Discover knots, the Lorenz attractor, a Möbius strip with one side and one edge, and the surprising geometry of the Klein bottle and Boy's surface. CHEMISTRY Fifty molecular and crystal structures in two complementary views: ball-and-stick reveals their connections; space-filling shows how atoms occupy space. See methane's tetrahedral shape, compare cyclohexane's chair and boat forms, or explore the repeating arrangement of a crystal. Colours identify elements, while Details explains the structure on screen. PHYSICS Look inside moving mechanisms, explore magnetic fields and trace light through lenses and cameras. Follow a watch movement, play a music box, watch a Jacquard loom or explore a canal lock and boat lift. The folding camera includes an image view with selectable apertures, so you can compare how the scene appears on its ground glass. SPACE Explore nine celestial bodies, their interiors, rings and available moon systems. See the Milky Way as a model built from measured galactic structure, with a clear marker showing our Solar System's position. Switch to the Orion Arm, or explore the Solar Neighbourhood, where labelled stars occupy positions based on astronomical measurements. ANATOMY Select several organs together and see how they fit within the same anatomical frame. Keep the torso skeleton visible for context or focus on the organs themselves. Explore the heart, lungs, liver, kidneys and their connecting structures. A separate head-and-neck model adds sectional views, selectable layers, air and food pathways, and a swallowing demonstration. BUILDINGS Explore architecture through whole models, cutaways and structural layers. Reveal the framework beneath a roof, inspect an interior or study how different parts form a building. The gallery also includes an animated ant nest, showing another kind of architecture beneath the ground. EXPLANATIONS BUILT IN Every entry includes a Details view explaining the current model. Formulas, measurements, sources and colour keys provide context, while the accompanying text explores what a shape causes, demonstrates or helps us understand. DESIGNED FOR IPHONE A landscape workspace gives models room to breathe. Drag to rotate, pinch to zoom and reset the view whenever you need. Browse a searchable catalogue and use simple controls tailored to each exhibit. Models, images and explanations are included in the app for offline exploration. WHAT'S INCLUDED 61 models are free to explore. One purchase permanently unlocks the remaining collection on iPhone, with no subscription. Existing Model Room Complete purchases can be restored. The iPhone purchase does not unlock the Vision Pro version.
