v1.0, requires Apple Shortcuts on iOS 12
Next Small Thing is a project-based task manager that doesn’t overwhelm you, because it only shows the next actionable item.
You create a project using plain text. The first line is the project name. The following lines are the tasks. You can start this text anywhere and send it to Next Small Thing via the Share button and the Shortcuts Action Extension, or you can enter the text when you run Next Small Thing.
When Next Small Thing shows you your next task, you have a few options. You can mark it as complete, or create a reminder (in Apple Reminders) at a particular time, or location.
You can edit the project, adding or removing tasks by simply editing the text. You can work with multiple projects, which are just tiny text files on your iCloud Drive. You can archive projects when they’re complete. And then you can get on with your life.
