SwiftoDo
SwiftoDo is a modern, powerful todo.txt app for iOS.
Features
A task list that you control
Your task list is a plain text file, not some proprietary format owned by a company or locked to a specific application.
A simple and timeless format
Plain text is the simplest file format there is. It will always be accessible, by some kind of application, forever.
Few rules to learn
Learn only a few simple formatting rules (which SwiftoDo will take care of for you) to indicate task priority, task completion, and so on.
A GTD-ready system
The todo.txt format was built with Getting Things Done in mind. It supports projects (which begin with “+”) and contexts (which begin with a “@“).
Use alongside any app on any platform
You can sync your task list with any app on any platform via any app that supports the Files app, or via the built-in Dropbox plugin.
Native
Built for iOS. At home on either the iPhone or the iPad.
