Give your Markdown files a calm, native home on iPhone and iPad. MDer brings together a document library, a focused editor, and a dedicated reading experience. ORGANIZE YOUR LIBRARY Search titles and document contents. Sort your library, use collection filters, mark favorites, and pin notes. Start with a template, duplicate a document, or restore a note from Recently Deleted. WRITE WITH FOCUS Apply Markdown formatting at the cursor or to selected text. Use native undo and redo, Find, and hardware keyboard shortcuts. Live word and character counts, estimated reading time, and automatic local saving help you keep writing. Clear save status and retry controls let you respond if a save fails. READ COMFORTABLY Enjoy serif typography, comfortable line lengths, adjustable text size, and Paper, Sepia, or Night themes. Read headings, nested lists, checklists, tables, quotes, code blocks, and reference links. Navigate with the heading outline and return to your saved reading position. Long code blocks scroll horizontally and can be copied. External images appear as placeholders rather than loading automatically.
