Light Lab vs Linear Algebra

Move light. Refract it. Reflect it. Light Lab is an interactive science app where you learn by playing with light. 【Discover the Magic of Light】 Touch the screen and move the light source. Rotate lenses and change refractive indices. Watch light rays change in real-time! Create rainbows, bounce light off mirrors. "Why does this happen?" As you play, you'll naturally understand how light works. 【Perfect For】 ・Students learning about light in elementary or middle school ・Anyone studying light propagation, reflection, and refraction ・Teachers who want to make science class more engaging ・Anyone curious about optics 【What You Can Do】 ◆ Real-Time Light Manipulation Move light sources and lenses to see light rays change instantly. Rotation, translation, refractive index changes—all operations reflect in real-time. ◆ Place Various Lenses Triangular prisms, convex lenses, concave lenses, diamonds, spheres, mirrors, and more. Place up to 10 lenses simultaneously to recreate complex light behaviors. ※2 lens types are free (triangle prism, biconvex lens) ◆ 3 Types of Light Sources ・Parallel: Like sunlight ・Spotlight: Like a light bulb ・Dispersion: Rainbow-colored light ◆ Create Animations Save lens and light arrangements as "scenes." Connect multiple scenes to create animations showing how light transforms. ◆ Save and Share Save your creations in the app. Generate QR codes to share with friends and classmates. 【For Teachers】 Designed as an educational tool for classroom use. ・Visually understand light propagation, reflection, and refraction ・Simulate phenomena that are difficult to explain, like total internal reflection and dispersion ・Students can experiment independently—perfect for inquiry-based learning ・Save and share scenes as teaching materials Try it for free first! 【Features in Detail】 ＜Light Source Adjustments＞ ・Position and rotation ・Adjust number of rays and width ＜Lens Adjustments＞ ・Position and rotation ・Refractive index settings ・Size adjustment ・Curvature adjustment for convex and concave lenses ＜Scene Features＞ ・Create up to 5 scenes ・Smooth animations between scenes ＜File Features＞ ・Local saving ・QR code sharing 【Pricing】 Basic features are free. ◆ Lens Unlock ($5.99/ One-time purchase) Unlock premium lenses (plano-convex lens, biconcave lens, diamond, sphere, mirror, reflector). ◆ Lens Ticket Issuing Feature ($11.99/ One-time purchase) ※Requires "Lens Unlock" purchase first Generate QR codes to unlock all lenses on other devices for 1 year. Tickets can be issued repeatedly—perfect for teachers adopting the app school-wide or classroom-wide. 【Privacy】 ・No personal information is collected ・Works offline by default ・Internet connection required only for accurate time retrieval when using Lens Ticket feature 【Requirements】 ・iPhone / iPad ・iOS 16.0 or later 【Support】 Detailed instructions are available in the in-app "How to Use" menu.

MatrixViz makes linear algebra and computer graphics understandable by turning the maths into interactive visuals. Built for complete beginners, MatrixViz lets you drag vectors, reshape matrices, move cameras, adjust projections, and immediately see what each formula does. Every learning module connects a plain-language idea to a guided experiment, a live visual, the underlying equation, and a symbol-by-symbol explanation. LEARN LINEAR ALGEBRA VISUALLY • Explore vectors in 2D and 3D • Turn matrix columns into draggable handles • See rotation, scale, shear, reflection, and composition happen live • Understand determinants, inverse matrices, span, basis, and independence • Discover eigenvectors by finding the directions a transformation cannot turn UNDERSTAND COMPUTER GRAPHICS • Follow coordinates from object space to the screen • Inspect model, view, and projection matrices • Compare perspective and orthographic projection • Learn cameras, frustums, lighting, normals, depth, blending, winding, and culling • Experiment with Metal shader patterns using beginner-friendly visual controls LEARN BY DOING • Guided lessons paired with the real interactive modules • Always-visible formulas and plain-language symbol keys • Sliders and direct manipulation instead of code-first controls • Saved sandbox presets for returning to experiments • Adaptive layouts for iPhone, iPad, Mac, and Apple Vision Pro • Light and dark appearance options MATRIXVIZ PRO Optional MatrixViz Pro unlocks iCloud lesson-progress sync, educator presentation mode, and 1080p matrix-animation export across supported Apple platforms. MatrixViz Pro Monthly and MatrixViz Pro Yearly are auto-renewable subscriptions. Payment is charged to your Apple Account when the purchase is confirmed. Subscriptions renew automatically unless canceled at least 24 hours before the current period ends. You can manage or cancel subscriptions in Apple Account Settings. MatrixViz Pro Lifetime is a one-time purchase and does not renew. Prices vary by storefront.
