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.
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.

Your todo.txt file isn't useful if it's not always at your fingertips. The Todo.txt mobile apps make it easy to view and update your tasks on the go.
Currently connected to Dropbox, Todo.txt Touch helps you manage your todo.txt on your touchscreen mobile device and automatically syncs your changes to all your computers.
Also available in the Amazon Appstore.
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.

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.
Several months in and I don't know how I got anything done before my @todotxt + @geektool + @Dropbox task tracking system.

Found @todotxt. Synch todo.txt with unix script, dropbox and an android app. Supports GTD contexts & projects. Nerdtastic!
