I too rarely take the time to discuss apps or services that I really enjoy, so I’m going to do jump ahead and do this now.

If you’re looking for an application to use with your task management (and especially if you’re into GTD), I highly recommend using Things*.

Things

You can install it on your Mac and iOS devices and with the newly updated version, it will cloud sync between all of them. The new version also brings a very cool and easy way interface for reviewing the tasks scheduled for the day and deciding on whether they should be done today or postponed, which I have found to be hugely useful in keeping the lists clean.
Other than that you get what you’d expect from a GTD-type task management application, with tasks, projects tags etc. But the attention to detail is significant and you can tell right from the start.

The new version also implements my favorite date picker to date in any app…ever! I’ve long complained about digital calendars trying to imitate paper ones, including their limitations. This is much better.

Take it for a spin and see for yourself.

* Apple world only though

PS: I’m neither affiliatted with the guys at Cultured Code, nor do I get paid for promoting this. But it really is a damn good app to have.
