Trello

Free (IAPs) | Needs iOS 12 or later

If you’re planning a big multi-stage project with lots of spinning plates that you need to keep track of at a glance, try this. Trello also works with task ‘cards’, but they are arranged on a ‘board’ (which can be shared) that’s divided into columns denoting different statuses. When you progress a task, simply move it from one column to another.
