WorkFlow is the privacy-first project manager built natively for iPhone and iPad. Free to try for 30 days, then a single one-time purchase unlocks everything for good โ€” no subscription, no account, no trackers. Your data lives in your iCloud, never on our servers. TEN WAYS TO SEE YOUR WORK Board, Calendar, Gantt, Today, My Day, My Work, Inbox, Dashboard, Documents and Notepad โ€” pick the ones you use, put them on the tab bar in the order you like, and choose which one the app opens on. Tap the Board tab again to page through your columns; tap any other tab again to jump back to the top. A NOTEPAD THAT TURNS INTO WORK Jot it down first, sort it out later. Notes capture thoughts, links and shared text the moment they arrive; when one grows up, turn it into a task or a whole project with everything it held. A review sweep walks you through what's waiting. INBOX: EVERY CONVERSATION, NEWEST FIRST Every task with a comment thread, unread on top. Tasks with something new to read carry a badge on the board and the Inbox tab counts them. Open the thread and it clears. Comments merge safely across devices โ€” nothing you write gets overwritten by a sync. WORKS WITH AN AI ASSISTANT Pair WorkFlow with WorkFlow for Mac and an assistant such as Claude Code can work your tasks: read them, create projects, tick off subtasks and reply in the comments. Assign a task to it or write "@claude" in a comment from your phone โ€” the Mac starts a session on its own and the reply comes back as a notification on your iPhone. Only projects you haven't shared are ever in scope. Requires WorkFlow for Mac and your own assistant, sold separately. COLLABORATE IN REAL TIME Share any project through iCloud. Invite people by iMessage, email or link. See who's viewing and who's typing, assign with a tap, @mention, react with emoji โ€” and every action in the activity log says who did it. GANTT AND CALENDAR Your whole portfolio on a timeline with a Today marker and days-until-due on every project. Two-way sync with Apple Calendar, so a due date changed in either app changes in both. STAY FOCUSED A built-in focus timer with 15, 25, 45 and 50-minute presets and auto-cycling breaks; every minute is logged against the task. Time tracking per task. Smart nudges raise a task's priority as its deadline nears. Snooze what can wait. CAPTURE EVERYTHING Share a link or text from any app straight into a task. Attach photos, files and voice notes; annotate images in place. Subtasks with their own documents, tags, priorities, recurring tasks, dependencies, and a note pinned to the top of any card. SMART LISTS Save any combination of filters as a named list โ€” "Overdue", "This week", "Waiting on me" โ€” one tap away. MAKE IT YOURS A gallery of task card styles, custom header and tab layouts, project colours and icons. Import from CSV or Apple Reminders; export CSV or JSON. Siri Shortcuts and actionable notifications. Full VoiceOver support, dark mode and Reduce Motion. PRIVACY BY DESIGN Zero analytics. Zero trackers. Sharing uses Apple's own iCloud sharing, end to end. We can't see your tasks โ€” and we don't want to. EVERYTHING INCLUDED - Board, Calendar, Gantt, Today, My Day, My Work, Inbox, Dashboard, Documents, Notepad - Notepad with note-to-task and note-to-project conversion - Inbox with unread badges and safe comment merging - Works with AI assistants through WorkFlow for Mac - Real-time sharing with presence, @mentions and reactions - Focus timer, time tracking, smart nudges, snooze - Subtasks, dependencies, recurrence, tags, pinned notes - Attachments, voice notes, photo annotation, share sheet - Smart Lists, two-way calendar sync, Siri Shortcuts - CSV and JSON import/export, Apple Reminders import - Full offline support with iCloud sync Free for 30 days. One purchase after that โ€” every feature, every update, forever.

Check the result Preview your compressed PDF and see its file size, page count, and percentage reduction. Your original PDF stays unchanged, so you can review the compressed copy before using it. Save, share, and find it again Save the result to Files or send it through the share sheet. Saved results remain available in History for previewing, sharing, renaming, or deleting later. Process your PDFs locally Compression runs locally without uploading your documents to a processing server. No app account is required. Choose the access that fits your needs Free access includes advertising and two successful compressions per day. Cancelled or failed attempts and results without a meaningful size reduction do not use your allowance. Previewing, saving, and sharing an existing result remain available without using another compression. Optional Pro access removes advertising and the daily compression limit. The same compression quality options are available with free and Pro access. Before you compress Compression converts each page into an image within the output PDF. Visual quality may decrease, and text in the compressed copy will no longer be selectable or searchable. Some PDFs may not become smaller, and a specific output size is not guaranteed. PDF Compressor lets you use the app at no cost. However, premium access may be available as an optional in-app upgrade.
