SymCalc+ vs TeXitor

Solve equations, simplify algebra, take derivatives and integrals, work with matrices, and visualize results in 2D and 3D from one app. Whether you need an exact symbolic answer, a decimal approximation, or a graph, SymCalc keeps the full workflow in one place. Store your work in reusable sessions, assign variables, define your own functions, and come back to your calculations later. - Solve single equations and systems with exact or numerical results - Simplify, factor, expand, substitute, and find roots, limits, sums, products, and Taylor series - Handle calculus tasks including derivatives, indefinite and definite integrals, and differential equations - Work with matrices and vectors: determinants, inverses, rank, RREF, eigenvalues, eigenvectors, dot products, and cross products - Graph standard functions, implicit equations and inequalities, polar curves, parametric plots, and 3D surfaces - Use logarithmic axes, inspect intersections, and adjust extra variables with sliders - Compute with complex numbers and common scientific functions - Save worksheets, keep multiple sessions, create custom functions, and export your work as PDF or SymCalc files - Learn faster with built-in function help and examples inside the app - Built for students, engineers, scientists, and anyone who needs more than a basic scientific calculator

TeXitor turns the intimidating task of writing mathematical and chemical formulas into something every student, teacher, and researcher can do in seconds — right on their iPad, iPhone, or Mac. Built with classrooms in mind, TeXitor lets you type LaTeX or Typst code and see your formula rendered instantly — no compiling, no waiting, no prior LaTeX experience required. Whether you're a chemistry teacher writing reaction equations, a student typesetting an exam solution, or a researcher preparing a paper, TeXitor gives you professional-grade scientific typography in a tool as simple as a notes app. KEY FEATURES FOR EDUCATION • Live formula preview — see your math and chemistry notation rendered as you type, powered by the industry-standard KaTeX (LaTeX) and Typst engines. • Chemistry made easy — full support for mhchem/Alchemist syntax. Write \ce{H2SO4} or ce("H2SO4") and get correctly formatted chemical formulas, reaction arrows, and equilibrium notation. • Custom keyboard toolbar — dedicated keys for fractions, roots, superscripts/subscripts, chemistry arrows, and common symbols mean less hunting for characters and more focus on content. • Templates & snippets — save frequently used formulas (reaction schemes, skeletal structures, common expressions) as one-tap templates, perfect for building a personal formula library over a semester. • Export anywhere — turn any formula into a PDF, scalable SVG, or plain .tex/.typ file for worksheets, slides, lab reports, or your school's LMS. • Undo/redo, including shake-to-undo — mistake-proof editing that feels natural for students working under time pressure. • Works with CU-Book — a seamless companion to the Worlddidac Award-winning CU-Book STEM learning system, used in classrooms to teach computer skills, data visualization, and scientific writing. BUILT FOR SCHOOLS, NOT JUST USERS TeXitor was designed from the ground up with data protection in mind — a rare feature in educational software: • No accounts, no sign-up, no login — students open the app and start writing immediately. • No personal data collected — no analytics, no tracking, no advertising IDs, no crash reporting. • Everything stays on the device — formulas, templates, and settings are stored locally; nothing is uploaded to a server. • GDPR-compliant by design — because no personal data is processed, TeXitor can be deployed on school devices without parental consent forms or data-protection sign-off. • Curated, whitelist-only web access — the few in-app help links open only in a locked-down in-app browser. No open web browsing, no unexpected content. • Safe for all ages, including young learners — no social features, no chat, no ads. Whether you're outfitting a school's device fleet, teaching a chemistry unit, or just need to typeset a formula for tomorrow's worksheet, TeXitor makes rigorous scientific notation approachable — without ever compromising on privacy.
