News: The Distributions app is now part of the all new "Art of Stat" app, which contains this and seven other modules. Please consider getting the Art of Stat app for the latest updates and features from the App Store. Simply search for "Ar of Stat" on the App Store. This app will continue to work, but future development is concentrated on the new Art of Stat app. Original Description: The Art of Stat: Distributions app explores and visualizes continuous and discrete probability distributions via sliders and buttons. Don't rely on boring and complicated graphing calculators that don't deserve their name. Instead, use the interactive graphics that this app provides to learn about probability distributions and visualize results side-by-side with the numerical solutions. Find probabilities or percentiles (two-tailed, upper tail or lower tail) for computing P-values or when working with discrete distributions. Obtain critical values for confidence intervals. Display the expected value and standard deviation, and simulate random numbers. The app works in offline (airplane) mode and indicates this by changing the background color. Continuous Distributions implemented so far: - Normal - Student's t - Chi-Squared - F - Exponential - Uniform - Gamma - Beta Discrete Distributions: - Binomial - Geometric - Poisson - Define Your Own Discrete Distribution, or choose from preloaded examples, such as Benford's Distribution of the leading digit
Simplex Linear Programming

Master the mechanics of Linear Programming with an industrial-grade, visual Simplex solver. Whether you are an undergraduate student tackling Operations Research homework or an engineer optimizing complex systems, this app provides a high-performance, native environment to solve and visualize linear models. Built with Apple’s Accelerate Framework (vDSP), the engine performs hardware-accelerated matrix operations for desktop-class speed on your mobile device. Why this is the ultimate optimization tool: Visualize the Feasible Region: See your constraints come to life on an interactive Canvas. Plot the quadrant, identify intersection points, and explore the feasible region with intuitive gestures. The Simplex Journey: Watch the algorithm navigate from the origin to the optimal solution. Our "Visual Walker" tracks every iteration, highlighting each vertex transition with a clear, orange path. Professional Grade Logic: Full support for Big-M and Two-Phase methods. Easily handle ≤, ≥, and = constraints without needing to manually convert your model. Precision Entry: Clean, monospaced interface featuring color-coded inputs for coefficients, objective goals, and variable signs. Education-First Design: Perfect for learning the geometry behind the algebra. Follow the path, analyze the coordinate labels, and see exactly where the "Optimal" solution sits in the coordinate plane. Purely Native: No web wrappers or lag. Experience a fluid SwiftUI interface designed for "Engineering Soul"—performance, clarity, and reliability. Student & Professional Value Proposition For Students: Use it as a powerful "Check Your Work" tool. Compare your manual pivot steps against the visual path and verify your feasible region boundaries. For Professionals: Quickly prototype constraints and objectives on the go with a solver that respects hardware limitations and mathematical rigor.

Verdict
The clearest difference is price: Art of Stat at Free against Simplex Linear Programming's $1.99. Art of Stat also leads on iOS requirement (15.1 vs 26.0). Simplex Linear Programming's advantage is in-app purchases (none vs 10). On ads and device support there is nothing between them.
