Here is a partial list of apps I’ve looked at:

So when it comes right down to it, the “right” app is probably more about its feel and a few features that make that feeling. You can usually prioritize and add notes. They let you break out your tasks into related groups. They have an inbox and built in views of what’s due today, tomorrow and other other points in the future. Most of these apps have similar features, many designed with the getting things done model in mind. Other than this, I am open to different methods of organizing tasks, at least as far as trying them out to see if they work for me. I’ve been looking at various task management applications.
