Do you spend hours solving algebraic matrices by hand, only to have a single sign error ruin your entire Linear Optimization exercise? Understanding the Simplex Algorithm in Operations Research can be frustrating. Current tools are clunky, confusing, and seem like they're from the 90s. DISCOVER SIMPLEX EDUCATIONAL The high-fidelity academic tool designed exclusively for iOS and iPadOS that transforms complex matrices into a fluid, readable, and intuitive visual experience. Perfect for students of Industrial Engineering, Economics, Business Administration, and optimization professionals. WHAT YOU CAN DO: โข Dynamic Model Builder: Switch between Maximization (Max Z) and Minimization (Min Z). Enter constraints with operators (โค, โฅ, =). โข Intelligent Engine: Automatic conversion to Standard Form (injecting slack, surplus, and artificial variables). โข Special Case Detection: Identifies unique, multiple (infinite), unbounded, or infeasible solutions without infinite loops. โข Local History with SwiftData: Audit your past problems instantly, without re-entering large matrices. CHOOSE HOW TO LEARN: 1. FINAL RESULT MODE (Free): Your executive success card. Visualize the optimal vertex with specific color codes (Green for unique solution, Purple for multiple). 2. STEP-BY-STEP MODE: An interactive learning log that details each iteration and pivot in ultra-readable, single-spaced tables. Access it for free through rewarded ads or unlock it forever. PRO PASS (One-Time Payment - No Subscriptions): Completely remove ads, unlock unlimited offline Step-by-Step Guides, and export your completed exercises as LaTeX code or professional PDFs.

Verdict
The clearest difference is ads: MyFormulae at none against Simplex's shown. MyFormulae also leads on iOS requirement (13.0 vs 26.0). On price, in-app purchases and device support there is nothing between them.
