More than just tasks, it includes GTD features for checklist tracking, habit tracking, goal setting and monitoring, 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.

The highly customizable task management options.

Toodledo has been around for a very long time and I have been a user and paying customer for a very long time as well. The application does a very good job for task management and offers a lost of options for the user to customize it to his own workflow and liking. The new owners are doing a very good job supporting the solution and making it evolve through time to remain competitive and relevant. It integrates well with many third party applications.
