Linprog solves linear programming and optimization problems step by step โ and shows the complete worked solution, not just the final answer. From a classic simplex tableau to the travelling salesman problem, it covers the operations research methods you actually study, and works fully offline. Whether you're a student checking coursework or solving a problem set, Linprog walks through each method in full, saves your work so you can revisit it, and presents results as exact fractions or decimals. OPERATIONS - Simplex method calculator - Dual simplex method calculator - Transportation problem โ potential method calculator - Assignment problem โ Hungarian method calculator - Travelling salesman problem calculator (TSP) - Game theory calculator - Dynamic programming calculator LINEAR PROGRAMMING Maximize or minimize a linear objective function under linear constraints. Linprog handles the full setup โ objective, constraints, and bounds โ and shows every pivot of the simplex (and dual simplex) algorithm so you can follow exactly how the optimum is reached. FEATURES - Full step-by-step solutions for every method - Custom keyboard for fast, convenient data entry - Save and edit your solutions - Works without an internet connection - Results as ordinary or decimal fractions Web version: https://linprog.com

Verdict
The clearest difference is in-app purchases: Linprog at none against CalC's 2. CalC's advantage is ads (none vs shown) and update cadence (every 4 days vs every 2 weeks). On price, device support and iOS requirement there is nothing between them.
