Keep your Markdown and text files close, from a quick note on iPhone to a longer writing session on iPad. READ AND WRITE IN THE SAME FILE Open documents through Files, create a Markdown file, or return to a recent document. Switch between Read and Edit, save changes explicitly, and use Undo, Redo, Find, or Find & replace while writing. Read Markdown as a formatted page, jump through Contents, and adjust reading and editor text sizes. WORK WITH YOUR FILES Browse folders, view PDFs and images, and share, rename, or duplicate a document. Files remain in the location you choose, including supported Files providers. A provider may require its own account or network connection. OPTIONAL SYNC WITH YOUR COMPUTER Connect a computer running Syncthing, approve your device on that computer, and choose matching shared Folder IDs. Download files, keep a shared folder available offline, and save edits for sending when the computer is reachable. Transfer activity distinguishes a local save from a revision confirmed by your computer. Review conflicting versions before choosing what to keep. YOU CHOOSE WHEN TO CONNECT Syncthing is off until you enable it. Local discovery, global discovery, and relays have separate connection settings. Background work depends on the time iOS grants; continuous background syncing is not promised. No Treo account is required.
