PocketCAS vs Cabri Express

PocketCAS is a graphing calculator for iPhone and iPad. It graphs your functions, finds derivatives and works with exact fractions and roots. Everything runs on your device, so it works without internet or an account. An in-app purchase unlocks PocketCAS Pro, with steps, integrals and the solver. Graphs - 2D plots of functions, implicit equations, polar and parametric curves and vector fields, two functions per plot. PocketCAS marks zeros, extrema and intersections. In full screen, tap a mark to read its coordinates. - 3D surfaces with soft light and shading. Drag to turn them, pinch to zoom. Derivatives - Under each function, a suggestion shows its derivative, already worked out, and a small plot sits beside the result. Tap one to add it to your document. - Exact derivatives of products, quotients, roots and chains, written the way your textbook writes them. Exact results - Arithmetic with exact fractions and roots, trigonometric, exponential and logarithmic functions. - Matrices: determinants, inverses and products. - Your own functions, with conditions and recursion. - Common units and physical constants. Reads like your textbook - Results look the way they do in a textbook: fractions, roots, powers and matrices. - A math keyboard with every function in reach, and a hint shows what goes between the brackets. Made for daily work - Documents keep your calculations and plots together, and iCloud syncs them between your devices. - Export and print plots, entries or whole documents (with a watermark). - Help built in: the function reference explains every function with examples, and tutorials get you started. Unlock PocketCAS Pro One purchase in the app unlocks everything in PocketCAS Pro, without a subscription: calculation steps that name the rule behind each step, integrals, limits, series and sums, equation and system solving, factoring and simplifying, eigenvalues, differential equations, scripts, plots with more than two functions, imports of documents and CSV data, larger matrices in the editor, exports without a watermark, and suggestions with zeros, extrema and integrals. Family Sharing is included, and Restore Purchases is in the main menu. Until you unlock it, the function reference marks the functions of Pro with a PRO badge. PocketCAS Pro is also sold as its own app; you need only one. Questions or ideas? Write to us at https://pocketcas.com/support.

Features of Cabri Express include a dynamic geometry environment, an agile calculator (scientific & graphic), a formula and equation editor. All wrapped in an intuitive app. With its friendly interface, Cabri Express allows students to visualize and manipulate abstract mathematical concepts in any topic: algebra, calculus, tables, functions, graphs, 2D & 3D geometry, transformation, statistics & trigonometry. The app is a laboratory in which they explore, model, and investigate without any limits. Cabri is free, it is the reference software for dynamic mathematics. It has been used for more than 25 years by millions and millions of teachers/students around the world.Good maths for students and power & ease for teachers, to teach math, not the software.
