SymboliX — the symbolic calculator that explains itself Type a problem and get an exact symbolic answer, typeset like a textbook. Every result is a card: differentiate it, integrate it, plot it, or open the step-by-step solution with one tap. COMPUTE • Derivatives, indefinite and definite integrals, limits, series • Equations and systems, with numeric roots when there is no closed form • Simplify, expand, factor (and prime-factorize integers) • Matrices: determinant, inverse, eigenvalues • Differential equations (desolve) SEE IT • Results that are functions plot themselves: definite integrals show their area, solved equations mark their roots • Full-screen graphing with pan, pinch-to-zoom and live updates as you type PROGRAM • An Xcas-style language: functions, local variables, for / while / repeat loops, recursion, lists, print output • Example programs: Fibonacci, primes, Newton's method, the Collatz sequence, matrices • Variables carry across cards; reset them any time STEPS AND THE AI TUTOR • Step-by-step solutions are free for everyone • Want to know why each step works? Unlock the AI tutor once: it explains the reasoning, the common traps and how to check the answer (100 walkthroughs a month; a one-time purchase, not a subscription) ALSO • Notebooks to keep your work • Computing, plotting and programming work offline and are free forever • English and Simplified Chinese

Verdict
The clearest difference is in-app purchases: ODE Solver + at none against SymboliX's 1. ODE Solver + also leads on update cadence (weekly vs every 5 weeks). SymboliX's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
