Science of Data is a mobile companion to two graduate-level books by Jean Claude Lemoyne Zabaloff — "The Science of Data" and "Data Science Project" — paired with an AI-powered ML Code Generator that produces complete, runnable scripts in Python, R, or MATLAB for any machine learning task you describe. 13 CHAPTERS What is AI? · Foundations · Supervised Learning · Unsupervised Learning · Reinforcement Learning · Deep Learning · Bayesian Inference · Support Vector Machines · Data Science · Knowledge · DS Process · Key Concepts 5 APPENDICES A — Python | B — R | C — MATLAB / Octave / Scilab D — Optimization | E — Public Data Sources ML CODE GENERATOR Describe any ML task or pick from 23 built-in templates and receive a complete, runnable script instantly. Languages — Python, R, MATLAB Templates — Classifiers · Regression · Cross-Validation · ROC Curve · Confusion Matrix · Feature Importance · Pipeline · Clustering · Neural Network · SVM · PCA · Preprocessing · Hyperparameter Tuning · Time Series · Bayesian Inference · Naive Bayes · Bayesian Regression · Metropolis-Hastings · Gibbs Sampling · MCMC Diagnostics · Gradient Descent · Constrained Optimization · Bayesian Optimization Every script includes type hints, WHY comments, labelled output, an expected-output block, and an install-command badge (pip install / install.packages / Requires:). Copy to clipboard or share via any app. Three AI-generated follow-up questions deepen understanding after every session. APP FEATURES · Full-text search across all chapters and appendices · Bookmarks for quick chapter access · Font size control: S / M / L / XL · Dark and light mode · Swipe navigation between chapters · Content tab + Notes / cheat-sheet tab per chapter · GFM table rendering with horizontal scroll · Dracula syntax highlighting — light-green comments, orange function calls, pink definitions, purple numbers IDEAL FOR Graduate ML and data science students, practitioners who want a rigorous pocket reference, engineers moving into ML, and anyone studying Bayesian or probabilistic methods. PRIVACY No account required. No personal data collected or stored. The ML Code Generator sends only your prompt text to Anthropic's Claude API; no personal information is ever transmitted.

Verdict
The clearest difference is ads: Data Scientific at none against Math101 Sketchy's shown. Math101 Sketchy's advantage is iOS requirement (13.0 vs 16.0). On price, in-app purchases and device support there is nothing between them.
