Duplex Print Helper - print on both sides, even with a printer that can't. Print the odd pages first, flip the stack, then print the even pages. That's the whole trick. This app makes the two PDFs for you and shows you the page order before anything goes to paper, so you don't waste a whole stack finding every back page upside down. One-time unlock. No subscription, no ads, no account to create, and your PDFs stay on your device. [What you get] - Two ready-to-print PDFs: front (odd pages) and back (even pages). Print them in the app, or export and share them to print anywhere. - A preview of both sides and the exact page order before you print. - Back pages ordered for top-feed or bottom-feed printers - the order changes with your printer. - If the backs still come out reversed, tap "Switch order" on the result screen. No re-splitting needed, and the choice is remembered. [3 steps] 1. Open your PDF 2. Check the front/back preview and choose how your printer feeds paper 3. Print the front PDF, flip the stack, print the back PDF [Why people use it] - Kids' homework - teachers keep asking for double-sided printouts - Office documents - the work printer has no duplex - Home - save paper without buying a new printer [Also included] - Convert Word, images, e-books and other formats to PDF - Works with inkjet, laser and most printers - Simple enough for anyone, including seniors --- If this saves you a ream of paper, a 5-star review helps more people find it!

MDReader

MDReader opens your Markdown files and folders and renders them properly. There is no library to import into, no account to create and no sync service in the middle. Your .md files stay exactly where you put them, and MDReader reads and writes them in place. FAST, EVEN ON BIG FILES A two-tier parser scans a document in a single pass and only fully parses the blocks you can actually see. A 10 MB file opens before other editors have finished showing a spinner, and scrolling stays smooth all the way down. RENDERS THE WHOLE OF MARKDOWN GitHub-flavoured Markdown with tables, task lists you can tick straight from reading mode, footnotes that jump both ways, YAML front matter shown as a card, LaTeX math inline and display, fenced code with syntax highlighting, and Mermaid diagrams rendered offline. AN EDITOR THAT STAYS OUT OF THE WAY Live syntax highlighting, lists that continue and renumber themselves, bold/italic/link shortcuts, find and replace, table and formula inserters, and paste an image to save it next to the document. Autosave goes through the system file coordinator, so editing alongside Obsidian, git or iCloud is safe. PICKS UP WHERE YOU LEFT OFF Reading position is restored to the pixel, per document, across relaunches, rotation and window resizes. FOLDER WORKSPACES (PRO) Open a whole folder: a repository's docs, an Obsidian vault, a Zettelkasten. Fuzzy quick-open, full-text search across every file in the folder, [[wiki-links]] with a backlinks panel, a front-matter tag browser, and read-only git status per file. Changes made by other apps are picked up in place, without losing your position. MORE IN PRO PDF export and print, publishing to GitHub Gist and Telegraph, presentation mode for slides, a custom theme editor with imported fonts, focus and typewriter modes, word-count goals, reading statistics, text-to-speech with follow-along highlighting, local version history with diffs, snippets, Vim keybindings, and an AI pack that summarises and rewrites entirely on device. BUILT FOR APPLE PLATFORMS One purchase covers iPhone, iPad and Mac. Keyboard shortcuts throughout, multiple windows, menu bar commands, a Share extension, Shortcuts actions, widgets, a URL scheme, Spotlight indexing, VoiceOver labels and Dynamic Type. PRIVACY MDReader collects nothing. No analytics SDK, no account, no server of ours to talk to. The only network traffic is what your own documents ask for, such as remote images, plus the publishing integrations you set up yourself. FREE AND PRO The reader and the single-file editor are free forever: all rendering including math and syntax highlighting, the base themes, table of contents, in-file search, HTML, Markdown and plain-text export, and position restore. Pro unlocks folder workspaces and the power features above, as a one-time purchase or as a yearly subscription with a free trial. SUBSCRIPTION AND PURCHASE DETAILS MDReader Pro (Yearly) - auto-renewable subscription, 1 year, USD 9.99 per year, including a 7-day free trial for new subscribers.
