PDF Reader Pro for Document helps you finish real PDF work on iPhone: read a report before a meeting, mark up a contract, turn a PDF into an Office file, or send just the pages someone needs. Read PDFs in a clean mobile viewer built for everyday documents: business reports, agreements, class notes, research papers, proposals, receipts, and more. Mark up what matters with highlights, underlines, strikethroughs, ink, shapes, and text notes. Select existing annotations to remove them, or update FreeText notes when your comments change. Convert PDFs to Word, Excel, PPT, or images when you need reusable files for work, school, or sharing. Encrypted PDFs are detected before conversion, so protected documents stay out of the conversion flow. Organize pages without going back to a desktop. Reorder pages, delete unwanted pages, merge documents, split files, or export only the pages you need. Free users can read and annotate PDFs, with limited conversion access. VIP unlocks full conversion plus advanced page tools. Download PDF Reader Pro for Document and make PDF work simpler on iPhone.

About

Cue

Read full description

Cue is a cozy corner for the internet you mean to come back to. No feeds, no noise, no account — just your queue, waiting for the right moment. SAVE WITHOUT LEAVING Tap Share in any app and pick Cue. Tag it and add a note right there in the share sheet — Cue never opens, and you stay exactly where you were reading. The preview catches up on its own, title and image and all. Copied a link? Cue offers it when you open the app. Beautiful previews work across the sites that usually resist them: YouTube, X, Instagram, Threads, Bluesky, Reddit, TikTok, Hacker News, GitHub, Wikipedia, arXiv and more. TAGS THAT ALMOST TAG THEMSELVES When you save, Cue suggests the tags you'd probably pick for that link — one tap files it. Tags sort themselves alphabetically, wear their own colors, and the tag box doubles as a live filter. Housekeeping is built in: merge duplicates, recolor, and see which tags have gone quiet. EVERY TAG BECOMES A SHELF Your Library keeps a shelf for each tag, so you can find things by how you filed them — and your archive is a shelf too. Search everything, or narrow by tag and by what kind of thing it is: Video, Post, Thread, Paper, Repo, Audio, Article, detected automatically. In the mood to watch something? Two taps. A QUEUE THAT ENDS Swipe a card to archive it when you're done, pin what matters, and enjoy the calm of an empty queue. Cue is designed to feel finished, not infinite. PRIVATE BY ARCHITECTURE - No account. No ads. No analytics. No tracking. - Everything lives on your device and syncs through your own private iCloud — we run no servers and cannot see your data. - Your library is yours: export it as JSON or CSV anytime, or erase everything with one tap. OPENS THE APPS YOU LOVE Optionally open saved links directly in their native apps — YouTube, X, Instagram, Spotify, Apple Music, GitHub and more. Cue is lovingly small: fast to open, quick to save, calm to browse. Give your someday-links a home.
