MalMath vs Xcas

MalMath is a math problem solver that explains steps and displays interactive graphs. It covers algebra, calculus, trigonometry, matrices, functions and arithmetic. Users can enter problems using photo input, analyze graphs, and save or share solutions and graphs. The app also generates practice problems across categories and difficulty levels. Its full solver works without an internet connection, and an interactive Math AI Assistant supports follow-up questions in chat. MalMath is available on Android, iOS and the web. Google Play lists English, German, Spanish, Italian, French, Turkish, Albanian, Croatian, Arabic, Portuguese, Azerbaijani, Russian and Japanese. The free plan is listed as free, and the App Store listing says free with in-app purchases. In-app options include Premium for 2.99 USD once, All access for $4.99 a month, and All access for $24.99 a year. The Premium listing does not say what it unlocks. MalMath’s privacy policy says it uses Firebase Analytics to analyze app use; Google Play reports no data collected or shared with third parties and encryption in transit.

Xcas is a free interface for computer algebra, geometry, graphs, spreadsheets, statistics, and programming. Its symbolic tools include arbitrary-precision arithmetic, polynomial operations, simplification, equation solving, calculus, and linear algebra. Users can build programmable dynamic 2-D geometry and work with 3-D geometry and graphs. The spreadsheet supports relative and absolute references, formal objects in cells, and one- and two-dimensional statistics, including regressions. Programming features include functions, variables, tests, loops, an editor, a debugger, and C-like, Maple, MuPAD, and TI89 syntax modes. Xcas runs on Android, iOS, Linux, macOS, web, and Windows. The browser version can work locally without installation or an internet connection, though it is less complete and slower than compiled desktop versions. The Giac library can be used from C++, Python, Java, and JavaScript programs; the site also describes LaTeX and TeXmacs interfaces. Xcas is free under GPL3, but commercial software inclusion requires contacting the makers about a dual license. The site offers tutorials, guides, a forum, and documentation, which it calls incomplete on its English overview.
