Due for iPhone and iPad: a great design example

Building iPhone applications is a lot about graphic design and user workflow. For complex applications, this can be a very big challenge. But what if the application is all about a very basic problem. Is it a challenge? You bet. Having a narrow scope is not enough to make your life easier as a developer. You can mess up big time. Here is an example of a very focused application design that make it a joy to use. This is Due for iPhone and iPad. (iTunes link).

I love this application design. More can be found on my other blog: http://buildingiphoneapps.posterous.com. Have a look why I love this app.
