Pick Milestones if
- You want a planner, not a writing tool.
- You want to spend zero time configuring before you can plan something.
- You're tired of Notion's web-app feel and want something that opens instantly on iPhone.
- You care that your project data stays in your own iCloud, not on a third-party server.
- You want milestones with deadlines, not 'a database of milestones with a date property'.
