ProjectBoard โ€” projects, tasks, notes, and files in one place. Everything a project needs lives together: the tasks, the notes, the files, and the conversation. No more scattering one project across four apps. PLAN YOUR DAY, NOT JUST YOUR LIST Drag a task onto the calendar to block time for it. Let Plan My Day pack your tasks into the gaps you actually have free โ€” it reads your real calendar, so it schedules around meetings instead of pretending they don't exist. Start a focus session and work a block at a time. TASKS THAT MATCH HOW YOU THINK Subtasks for the steps. #tags across projects. Saved smart lists for the views you return to. An Inbox that catches anything you haven't sorted yet. WRITES THE BORING PARTS FOR YOU โ€” ON DEVICE Smart Fill turns a sentence into a task with the right date, project, and priority. Your Daily Brief tells you what matters this morning. Smart Inbox Triage sorts what piled up. Search understands what you meant, not just what you typed. It runs on your device. ON EVERY SCREEN YOU OWN A genuine Mac app โ€” split view, menu bar commands, keyboard shortcuts throughout. iPhone and iPad. An Apple Watch app for checking off work from your wrist. Home and Lock Screen widgets you can tap to complete a task. Shortcuts and voice for capture without opening anything. FILES WHERE YOU EXPECT THEM A ProjectBoard folder in Finder and the Files app, syncing both ways. Open documents straight in from Finder, or share them in from any app. Annotate with inline markup. BUILT FOR WORKING TOGETHER Share a project, chat alongside the work, and watch tasks and notes update live as your team moves. START FASTER Seven built-in project templates, or build your own with tasks that schedule themselves relative to your start date or deadline.
