Perfect to-do list if you want simplicity and ease of use

I have tried nearly every to-do list available for the Mac. While many of them are very good apps, they tend to be too feature-heavy to be convenient and easy to use. This app is perfect if you want to keep your lists handy and you want a clean, intuitive interface. Ive built a nice and easy Kanban board on my desktop using multiple lists. Its easy to drag list items from one list to another or within the same list, to add list items and so on.
I also have the iPhone app and the sync between desktop and mobile is quick and quiet using Dropbox.
