Todo.txt
Many power users attempt dozens of to-do list software programs, only to return to their todo.txt files. It can be difficult to open todo.txt on your touchscreen device or at the command line. That's where the Todo.txt apps come in. There won't be many drop-downs or reminders here. Todo.txt apps offer minimal, todo.txt focused editors that help you manage your tasks in as few keystrokes as possible. Numerous productivity apps and websites store your tasks in their own file format and proprietary database. You can use your todo.txt file with any text editor, regardless of the operating system or vendor.
