Formula Canvas vs Paperwrist

Formula Canvas is a native math workspace for writing formulas, building study notes, and preparing clean LaTeX without fighting plain text syntax. Create expressions visually with a structured math keyboard. Add fractions, radicals, superscripts, subscripts, sums, products, integrals, scalable brackets, matrices, equation systems, accents, Greek letters, arrows, relations, set symbols, and common functions. Tap to place the cursor, move through formula structures with direction controls, and undo or redo edits as you work. The live LaTeX preview keeps your source visible while you edit. Copy LaTeX instantly, or unlock advanced export and sharing with Formula Canvas Pro. Formula Canvas also includes a document workspace for longer notes. Combine text blocks, formula blocks, and handwriting blocks in the same document, then keep everything organized in a local document list. Use the drawing canvas for quick geometry sketches, annotations, diagrams, and handwritten ideas. Apple Pencil is supported through PencilKit, and built-in shape stamps help you insert lines, arrows, rectangles, and ellipses quickly.
