Running late? Tap once and your whole day rebuilds itself. Set is a planner built around time. Every task has a length and a start time, so you always know what is next and when your day will really finish. When the morning slips, you don't redo the maths in your head. You tap Reschedule, and everything moves. ONE-TAP RESCHEDULE - Everything overdue moves forward from right now, in order - Meetings and tasks pinned to a time keep their slot, and the rest fit around them - Plan more than a day can hold and Set tells you, then moves the overflow to the days ahead - Nothing is quietly shortened to fit: six hours of work never becomes four - Drag to reorder and every start time updates as you go YOUR CALENDAR AND REMINDERS, IN ONE PLAN (PRO) - Calendar events sit in your timeline at their real times, so a meeting at eleven is never a surprise at ten to - Events stay in your calendar. Nothing is copied, so nothing is duplicated - Tasks you create in Set can add events to a calendar of your choosing - Reminders sync both ways, and each list can arrive as its own project - Prefer hands off? Import Only reads your calendar and reminders and never writes to them A TIMER THAT BLOCKS DISTRACTIONS - A continuous timer, not rigid Pomodoro blocks, that records the time you really spent - Overtime counts into the negative for a little deadline pressure - App Blocker (Pro, iPhone and iPad): block chosen apps while the timer runs, or allow only the ones you need - Or pick "Until Today is clear", where finishing your plan is what unlocks your phone - Breaks are never blocked - Ambient sounds, Lock Screen, Dynamic Island, and a menu bar timer on Mac NOTES THAT DO MORE (PRO) - Write notes in Markdown: headings, checklists, highlights, links, code and more - A formatting toolbar and live preview, so you never need to learn the syntax - AI rewriting with on-device Apple Intelligence tidies messy notes or turns them into clear steps EXPORT TO PDF - Export Today, any project or your Inbox as a clean, styled PDF, ready to print or send - Include notes and subtasks, or go black and white for printing - Markdown and Rich Text too, or email a list with both attached - PDF export is free for everyone SCAN ANY LIST (PRO) Photograph a handwritten list or planner page and Set turns it into scheduled tasks, with durations and dates. On device, with Apple Intelligence. APPLE WATCH - Today's timeline on your wrist: tap to complete, drag to reorder, add breaks, Reschedule - The timer runs on the watch when your iPhone is out of reach, then hands back - Complications, Smart Stack and dictated tasks PROJECTS, STAGES AND INBOX - Capture anything in the Inbox and sort it later - Break big work into projects and stages, with progress bars - Subtasks and templates (Pro), repeating tasks with streaks, due dates - Type "45m", "tomorrow" or "at 2pm" and Set fills in the details - Swipe down for the week strip to plan any day, and drag a task onto a date to move it MADE FOR ADHD MINDS Time blindness is easier to fight when time is visible. Focus mode shows only the task in front of you, and Sort mode takes a long list one question at a time. No more "wait, it's already 8pm?" EVERYWHERE YOU ARE iPhone, iPad, Mac and Apple Watch, synced through your own iCloud with no account to create. Widgets, Live Activities, Siri, Shortcuts and the Action button. Stats and achievements, themes and accent colours (Pro). Undo and redo everywhere.
