Stack is a project planner built the way a Mac app should be. Lay work out on boards, see the same work on a calendar, and watch it run on a timeline — on iPhone, iPad and Mac, with everything synced privately through your own iCloud. BOARDS THAT MOVE Lists and tasks you can drag anywhere. Colour-coded labels, cover images, checklists, due dates, priorities, attachments and comments. Give a board a key and every task gets a number you can quote — HRB-14. THREE WAYS TO SEE THE SAME WORK Columns when you are running the work. One long list when you are working through it. A month calendar when you need to know what lands when — and a timeline of lanes and bars when you need to see the whole project at once. PLAN ITEMS, NOT JUST TASKS "Design freeze". "Launch". Dates a project has to remember that are nobody's to-do. They sit on the calendar and the timeline beside the work without pretending to be tasks. TODAY, THIS WEEK, FLAGGED Saved views that cut across every board, so you can start the day in one place instead of opening four boards to find out what is due. FIND ANYTHING Full-text search across every board — titles, descriptions, checklists and attachment names — with the board and list each result came from. SHARE A BOARD Invite someone with a link. They see your board, you see their edits, and it all runs on iCloud sharing. No accounts to create, no seats to buy. EVERYWHERE YOU WORK Quick add from anywhere. A menu bar item on Mac. A share extension so anything you are looking at can become a task. A home-screen widget for what is due today. Shortcuts and Siri support for the rest. WORKS OFFLINE, ALWAYS Every read and every write happens on your device first. Sync catches up when the network does. A plane, a basement, a bad hotel — the app does not care. PRIVATE BY DESIGN No account. No server. No tracking. No ads. Your boards live on your device and sync through your personal iCloud — nobody else can see them, including us. Free, with no subscription and nothing to unlock. Built natively for iPhone, iPad and Mac, localized into six languages, and designed to feel at home on every screen size.

Verdict
The clearest difference is in-app purchases: Stack at none against Simple Memo's 1. Stack also leads on ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
