Arohan vs ML_Engineering

Most learning apps ask you to watch. Arohan asks you to think. Every lesson is a card you read in a minute — and before the answer lands, you guess. That one habit is the whole difference: you remember what you had to reach for. TWO WAYS TO LEARN • Courses - structured roadmaps that take you from zero to fluent, one module at a time. Follow the path, tap through the cards, and let spaced revision resurface what you're about to forget. • Conversations - Socratic debates you read one turn at a time. Vera poses the hard question, you take your guess, and Osei walks you through the real answer. It's the "wait, why?" moment, on purpose. BUILT FOR HOW MEMORY ACTUALLY WORKS • Two-minute cards — learn in the gaps of your day • Guess-then-reveal — recall beats re-reading, every time • Spaced revision — the right card comes back at the right moment • Check what stuck — quick quizzes that find your blind spots GO DEEP ON ANYTHING From Spanish to system design, cybersecurity to investing, ancient history to reading an ECG. Prepping for nursing, engineering, civil services, law, science, or finance? The topics meet you where you are. NO CRAMMING. NO FLUFF. No autoplay lectures. No 40-minute videos you'll never finish. Just clean, honest cards on paper-warm pages and conversations worth having. Guess, then find out.

Become a machine learning engineer—starting exactly where you are. ML_Engineering is a complete interactive learning environment for iPhone, iPad, and Mac. Begin with basic arithmetic, examples, features, labels, and your first prediction baseline. Progress through Python, NumPy, pandas, statistics, feature engineering, classical machine learning, deep learning, computer vision, NLP, forecasting, recommendations, model serving, MLOps, monitoring, responsible ML, distributed training, LLM systems, and principal-level ML architecture. LEARN BY DOING • 40 structured courses from beginner to advanced • 400 substantive interactive lessons • 140 editable, syntax-highlighted code labs • 100 quizzes with validation and explanations • 80 architecture decisions based on production trade-offs • 80 guided concept exercises • Progressive hints that help without giving away the answer BUILD A SERIOUS ML PORTFOLIO Complete 40 practical projects: 12 Beginner, 14 Intermediate, and 14 Advanced. Build baselines, classifiers, forecasts, recommenders, vision and language models, feature stores, inference services, experiment systems, model registries, drift monitors, ML delivery pipelines, distributed training, LLM evaluation, governance controls, and a principal ML platform design. Every project includes an editable workspace, four milestones, checks, and outcomes you can explain in an interview. YOUR PRIVATE ML ENGINEERING TUTOR Ask from any lesson or project. Tutor Core can begin with basic arithmetic, define every new term, explain how models learn, diagnose code and architecture, and continue until the idea clicks. Offline Core is included and never sends questions anywhere. Compatible devices can add private Apple on-device generation. API, Ollama, and LM Studio connections are always optional. WATCH YOUR ML SYSTEM TAKE SHAPE Every completed lesson, course, and milestone advances a living ML-system construction scene—from problem framing and a baseline through features, training, serving, monitoring, and production guardrails. DESIGNED FOR SERIOUS PROGRESS Earn XP, build streaks, bookmark material, track role readiness, choose daily goals, switch between light and dark interfaces, and move naturally among iPhone, iPad, and Mac. FREEMIUM AND PRO Explore the first module of every course for free, keep your learning progress, and upgrade only when you are ready. ML_Engineering Pro unlocks the complete curriculum, every lab and portfolio project, and contextual Tutor access across iPhone, iPad, and Mac.
