Palmory is a mobile viewer for Markdown notes, HTML artifacts, PDFs, and related files hosted in GitHub repositories. It is built for browsing knowledge vaults, design docs, research notes, and AI-generated HTML reports on mobile. Use Palmory to open a repository, browse folders, read Markdown, view safe HTML artifacts, search your indexed content, and return to recently opened notes. Palmory stores your GitHub token in local secure storage on your device and keeps repository indexes and cached content local to the app. The current release focuses on viewing and search. It does not edit repository files, commit changes, push branches, resolve merge conflicts, or run a backend operated by GAVRRI. It also does not include ads, tracking, or paid features. Palmory is an independent app and is not affiliated with GitHub, Inc.

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. OPEN FILES, KEEP CONTROL ⢠Import Markdown and plain-text files, including multiple files at once ⢠Open Markdown documents from Files ⢠Export and share standard Markdown through the iOS share sheet ⢠Recover notes from Recently Deleted before permanent removal ⢠Keep document content locally without creating an account ⢠Use layouts that adapt to iPhone, iPad, larger text, and the software keyboard PRIVATE DOCUMENTS MDer does not include an AI service and does not send document titles or content to AI providers. Documents are stored on your device. You choose when to export or share them. MDer Pro is ad-free. MDer Free displays a Google AdMob banner and hides it while the software keyboard is open. Advertising privacy options are available when required. Advertising data is handled separately from document content; details appear in the App Store privacy label and privacy policy.
