LatentLens
Read full descriptionHide full description
LatentLens teaches artificial intelligence the way a great teacher would ā by starting with something you already understand. Every lesson opens with a familiar analogy from everyday life. Then it shows you where that analogy breaks down. Then it gives you the real concept, visualised and interactive, so you can see exactly how the pieces fit together. No maths degree. No prerequisites. No jargon before the intuition. ā WHAT YOU'LL LEARN ā 6 pillars. 39 lessons. Every major concept in modern AI, built up from first principles. ⢠Foundations ā the maths behind every AI model: vectors, calculus, probability, information theory ⢠Machine Learning ā how computers learn from examples: regression, classification, decision trees, clustering, reinforcement learning ⢠Deep Learning ā neural networks that see, hear, and create: perceptrons, backpropagation, CNNs, generative models ⢠Language & LLMs ā how AI reads and writes: tokenisation, embeddings, the Transformer architecture, LLM agents, hallucination ⢠Applied AI ā techniques you can use today: prompt engineering, RAG systems, fine-tuning, model deployment, AI product design ⢠Ethics & Safety ā making AI responsible: bias, interpretability, AI safety, governance, environmental impact ā HOW EACH LESSON WORKS ā Every lesson follows the same seven-step arc: 1. What you know ā an analogy from everyday life that mirrors the AI concept 2. The challenge ā why the everyday version breaks down at scale 3. The insight ā the key idea that bridges the gap 4. Picture it ā a custom illustration of the concept 5. See it work ā an interactive visualisation you control 6. The name ā the precise technical vocabulary 7. Try it ā a transfer question in a completely new context Each lesson takes about 8ā12 minutes. You can pause, pick up exactly where you left off, and revisit any step. ā 9 INTERACTIVE PLAYGROUNDS ā Lessons don't describe ā they show. Drag points on a regression canvas. Watch gradient descent find the minimum in real time. Build a K-means clustering result step by step. Explore how model complexity creates overfitting. These aren't videos. They're hands-on. Visualisations include: vector playground, gradient descent animator, distribution explorer, decision boundary explorer, tree builder, K-means stepper, regression canvas, feature encoder, and complexity slider. ā PROGRESS AND GAMIFICATION ā ⢠XP points and a level system for every completed lesson ⢠Daily streaks with a built-in freeze so one missed day doesn't wipe your record ⢠8 badges for milestones: first lesson, pillar completions, 7-day streak, quiz mastery, and more ⢠Full lesson history with quiz scores and completion dates ⢠Resume any lesson mid-step ā your exact position is saved ā FREE TO START ā The first lesson of Foundations and the first lesson of Machine Learning are permanently free ā no account required, no login, no timer, no trial. Just open the app and learn. Upgrade to LatentLens Pro to unlock all 39 lessons: ⢠Monthly ā $1.99 / month, cancel anytime ⢠Annual ā $7.99 / year (best value ā $0.67/month) ⢠Lifetime ā $9.99, one-time purchase Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current period.

Linear Algebra

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.

Verdict
LatentLens and Linear Algebra are too close to call on the numbers: across 5 compared parameters ā price, ads, in-app purchases and device support among them ā neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
Scored on Price Ā· Rating Ā· Positive reviews Ā· Number of ratings Ā· Update frequency Ā· Ads Ā· In-app purchases Ā· Monetization Ā· Best chart rank Ā· Devices Ā· Requires iOS
Both are free to download. LatentLens sells 3 in-app purchases, starting at $1.99 per month and Linear Algebra sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
