If you have a file called todo.txt on your computer right now, you're in the right place.
So many power users try dozens of complicated todo list software applications, only to go right back to their trusty todo.txt file.
But it's not easy to open todo.txt, make a change, and save it—especially on your touchscreen device and at the command line. Todo.txt apps solve that problem.
Simplicity is todo.txt's core value.
You're not going to find many checkboxes, drop-downs, reminders, or date pickers here.
Todo.txt apps are minimal, todo.txt-focused editors which help you manage your tasks with as few keystrokes and taps possible.
At the Command Line
With a simple but powerful shell script called todo.sh, you can interact with todo.txt at the command line for quick and easy, Unix-y access.
The Todo.txt CLI supports archiving completed tasks to done.txt and priority/context tab autocompletion.

In Any Text Editor
Countless productivity apps and sites store your tasks in their own proprietary database and file format. But you can work with your todo.txt file in every text editor ever made, regardless of operating system or vendor.
The todo.txt format is a simple set of rules that make todo.txt both human and machine-readable. The format supports priorities, creation and completion dates, projects and contexts. That's all you need to be productive. See an example Todo.txt file.
