I'm always looking for tools that show a lot of information, making it easy to scan. Too many tools nowadays seem built for phones and tablets only, with a TON of white space - which on a desktop, is all wasted space. On Toodledo I can see a lot more tasks or lists than on many other tools, because the views are compact. Love it!

It has a very flexible and robust set of folders, contexts, and even tags. Allows you to manage the different type of tasks across different projects. The recurring feature is also highly flexible allowing me to choose certain weekdays and even specific days of the week, or even after an arbitrary number of days. It may not have the most modern interface, but it is rock solid. If one cares about getting things done then this is the app to use.

More than just tasks, it includes GTD features for checklist tracking, habit tracking, goal setting and monintoring, easy to use on multiple devices, and integrates with my calendar. And, the few times I've needed support they've been responsive. It's my daily task manager, and the only one I've stuck with over the years - and I've tried MANY.
