Read full description

Relay is the project planner built for small teams and software businesses that need more than a to-do list. Plan work your way — kanban boards for tracking status, checklists for straightforward task lists, a freeform canvas for sketching ideas with sticky notes and links, and rich-text notes for meeting recaps and specs. Pick the board type that fits the work instead of forcing everything into one format. BOARDS, YOUR WAY • Kanban boards with custom columns and drag-and-drop cards • Checklist-style list boards with priorities, due dates, and labels • A freeform canvas for sketching out ideas — sticky notes, text, and links • Notes boards with a full rich-text editor for specs and meeting notes STAY ON TOP OF EVERYTHING • My Work pulls every task assigned to you into one place • A calendar view shows what's due, day by day • Local reminders notify you right when something's due — no account or server required • Global search finds any board, task, or note in seconds BUILT FOR TEAMS • Real accounts with Sign in with Apple — the same account on your Mac and iPhone • Assign tasks to teammates and set up a reporting hierarchy • Message your team directly in the app to keep work moving • Task comments keep context and discussion attached to the work itself DESIGNED FOR MAC AND IPHONE • A genuinely native experience on both platforms — not a stretched-out phone app on your Mac • Six accent colors to make Relay feel like yours • Profile photos for you and your team YOUR DATA, YOUR DEVICE Boards, tasks, and notes live on your device. Team messaging is delivered through Apple's iCloud — nothing is sold, and there's no advertising or tracking. Relay is for anyone who's outgrown sticky notes and spreadsheets but doesn't want the bloat of enterprise project management software. Simple enough to open and start planning, powerful enough to run a real team.
