MathWrite Notes

Features
Read full description

MathWrite Notes turns your handwritten maths into LaTeX. Write on the page as you always do, with Apple Pencil on iPad or on iPhone, and MathWrite converts each page into clean, structured LaTeX and compiles it into a typeset PDF. HOW IT WORKS โ€ข Write a page by hand. โ€ข At the end of the page, pull down and hold to add a new one. The page you leave behind turns into LaTeX on its own. โ€ข Open the LaTeX tab to see the source, or the PDF to see it typeset. On iPad in landscape, the source and the PDF sit side by side, and you can put your handwriting next to the PDF to compare them. A NOTEBOOK BUILT FOR MATHS โ€ข Blank, ruled, grid or dotted pages, in portrait or landscape. โ€ข Draw and hold: a stroke held still at its end becomes a perfect line, circle, rectangle, triangle or arrow. โ€ข The shapes tool places lines, arrows, axes and polygons with a single drag. โ€ข The graph pencil: write a function such as y = sin x and get its graph, drawn in ink you can move, resize and adjust. โ€ข Insert photos on the page. โ€ข Apple Pencil only mode, so your hand can rest on the screen, and a read-only mode for reviewing. โ€ข Folders, favourites, search and dark mode. LATEX THE WAY YOU WANT IT โ€ข Three styles: Classic, Tagged and Boxed. โ€ข Conversion settings: page layout, font size, margins, title and table of contents, equation numbering, what to do with diagrams, crossed-out work and margin notes, and whether photos are converted or inserted as images. โ€ข Your notes keep their own language, and theorem and proof headings follow it. โ€ข Every page is checked before it reaches you, and if a page would break your document, MathWrite repairs it so the PDF keeps compiling. YOUR PAPERS AND PDFS TOO โ€ข Scan pages with the camera, choose photos or import a PDF, and convert them to LaTeX. โ€ข Import a PDF from another notes app as a notebook and keep writing on top of it. SHARE AND EXPORT โ€ข Copy the LaTeX, share the .tex file, or open it in Overleaf in one tap. โ€ข Export the typeset PDF, or your handwriting as a PDF. PRIVATE BY DESIGN Your notebooks are stored on your device. Pages leave it only to be converted, and our server does not keep them. MATHWRITE PRO MathWrite Notes is free to download.
