The tile delivery slips by a week. Now the electrician can't start, your painter has taken another job, and a project you built around one long weekend has quietly moved into next month. A checklist never warns you about that. A timeline does. gantt puts the whole project on one chart and connects the tasks that actually depend on each other. Move one bar and everything downstream moves with it, including the steps you had forgotten were downstream. WHAT PEOPLE PLAN HERE A kitchen renovation with three trades, each waiting on the last one to finish. A thesis with a defense date nobody is moving. A wedding, a relocation, a trip stacked on non-refundable bookings. Client work you have run before and will run again next quarter. HOW IT WORKS Zoom the timeline from minutes to months, whatever the project needs. Link the dependent tasks and set the gap between them: two days for paint to cure, a week for a delivery. Switch on the working calendar and the plan stops counting weekends, your days off, and public holidays in your country. Split the big items into subtasks, tag them, add reminders, and fill in progress as you go. Then something changes, because something always changes. You drag one date and read the new finish date straight off the chart. FREE The timeline, tasks, subtasks, progress, tags, filters, reminders, Apple Calendar sync, the Apple Watch app, export as an image and sending a plan as a link. No ads, no trial countdown. WITH PRO Task dependencies and automatic rescheduling, a workweek you define, public holidays by country, export to PDF or a spreadsheet, and a Home Screen widget. NO ACCOUNT There is no sign-up screen because there is nothing to sign into. Projects sync across your devices through your iCloud. When someone else needs the plan, send it as a link in Messages: they open it without installing anything. Monthly Pro includes a free first month for eligible new subscribers and renews until you cancel. Lifetime Pro is a single payment.
