Notedown vs OneMarkup

Notedown is a featherweight markdown notes app for people who just want to write. No accounts, no sync, no clutter — every note is saved as a plain .md text file on your device and never leaves it. WRITE IN MARKDOWN Use familiar markdown to structure your thoughts: headings, bold and italic, bulleted lists, checkboxes, quotes, code, and links. A one-tap formatting toolbar inserts the syntax for you, so you never have to remember it. EDIT OR PREVIEW Flip between a distraction-free editor and a clean rendered preview with a single tap. See exactly how your note looks, then jump back to writing. FULLY OFFLINE, FULLY YOURS Your notes are stored as standard markdown files in the app's own folder on your device. There is no cloud, no login, and nothing to set up. What you write stays with you. FIND ANYTHING FAST Search across all of your notes instantly. The list keeps your most recently edited notes at the top. SHARE WHEN YOU WANT Export any note as markdown text through the standard share sheet. SIMPLE BY DESIGN - Light and dark themes - English and Japanese - Portrait, one-handed friendly layout - Free to use (contains ads) Notedown is the calm, lightweight alternative to heavy note apps — just markdown, and nothing in your way.

Open and inspect the files people actually send you—from Files, Mail, WeChat, and any app that shares documents. Ordinary file preview, search, and editing stay on your device, with no account, ads, analytics, tracking, or in-app purchases. PREVIEW MORE FILES • PDF, common and modern image formats including WebP and AVIF, Office/iWork, audio/video, and USDZ with iOS system controls • Complete ZIP website exports with index.html plus local CSS, images, fonts, and media • CBZ comics, ZIP-compatible package contents, GLB structure, fonts, certificates, property lists, email, source files, and unknown binaries READ AND EDIT Read Obsidian-style Markdown with a table of contents, heading jumps, tasks, callouts, footnotes, frontmatter, tags, and wide tables. Edit text-based formats through a Files-visible working copy while the original stays untouched. TRUSTED HTML MINI APPS HTML and ZIP websites open as isolated trusted-network mini apps by default: JavaScript and package assets can run, while network access is limited to HTTPS/WSS. Switch to Offline Mini App or Safe Preview at any time. HTTP/FTP, embedded frames, unexpected in-view navigation, and arbitrary access to other local files remain blocked. Webpage code can still contact third-party servers or send information you enter when its own logic requests it. QUICK ACCESS Recent files automatically appear in widget choices. Add multiple OneMarkup widgets, then choose a different file, name, and icon for each—including HTML mini apps. Small files are kept as local copies by default so source permissions cannot strand a shortcut.
