Neural Network Academy Lite vs Linear Algebra

Neural Network Academy Lite makes artificial intelligence hands-on, approachable, and genuinely fun. Whether you're a student, a curious adult, or a developer new to machine learning, this app guides you from "what even is a neuron?" to training real AI on your own photos -- no experience needed. LESSONS Five bite-sized lessons cover the ideas behind every modern AI system: - What is a Neuron? -- drag sliders and watch a single neuron compute in real time - Weights & Bias -- see exactly how small number changes shift a network's output - Activation Functions -- explore sigmoid and ReLU on live interactive graphs - How Networks Learn -- follow a forward pass step by step with animated signal flow - Backpropagation -- understand the algorithm behind every AI you've ever used Each lesson ends with a quiz that locks in what you've learned and earns XP to unlock the next tool. PLAYGROUND Train a real neural network on classic logic problems: XOR, AND, and OR. Watch the live loss curve fall as your network finds the pattern. Adjust layer count, neuron count, and learning rate -- then hit Train and see the math work. NETWORK BUILDER Design your own architecture from scratch. Add layers, set neuron counts, and watch the signal flow forward through your custom network before training begins. HOT DOG LAB Draw examples directly on a pixel canvas, label them, and train a classifier on your own drawings. Works with any two categories you choose -- a playful introduction to image classification. PHOTO CLASSIFIER The most powerful tool in the app. Pick two categories, add photos from your library, tap Train, and watch a real model learn to tell them apart. Test it instantly with any new photo. BUILT FOR LEARNING - XP and level system keeps you motivated and on track - Lessons unlock progressively -- concepts build on each other naturally - Every idea has an interactive demo, not just a wall of text - Live training animations show loss dropping in real time - Clean native iOS design -- no ads, no subscriptions, no account needed Neural Network Academy Lite is for anyone who has ever wondered how AI actually works. Not just how to use it -- how it thinks.

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.
