I created TaskPaper as an alternative to more complex task manager databases. I think that most people are better served by TaskPaper’s simpler solution.
Works like a text editor
Type your lists into TaskPaper and each line is formatted into a project, task, or note. TaskPaper doesn’t force a particular system on you; it provides you with basic to-do list elements and then you use them as you see fit.
Feels like a magic piece of paper
TaskPaper has a magic trick. It understands your list's structure and will instantly filter your list to show only items of interest. TaskPaper’s filter system is simple to use—focus on a particular project or tag with a single tap. It also supports advanced searching if need.
Stay synced between work, home, and your iPhone/iPad/iPod touch
TaskPaper uses the Dropbox.com sync service to keep your files synced. TaskPaper for iOS has Dropbox sync built in. TaskPaper for Mac can use the Dropbox client to stay synced with the iOS version.
