Was macht eine Applikation iPhone-Like? Worauf sollten sich iPhone-Programmierer in erster Linie konzentrieren? Und warum ist Apples Notiz-Applikation eines der besten Beispiele für gelungene iPhone-Software.

John Gruber setzt sich mit den oben genannten Fragen auseinander und macht einen guten Punkt.

I’ll put forth one central, overriding guideline for iPhone UI design:

Figure out the absolute least you need to do to implement the idea, do just that, and then polish the hell out of the experience.

I further suggest the following, more specific, guidelines:

• Each screen should display one thing at a time. That “thing” may be a list, but it should just be a list.

• Minimize the number of on-screen elements.

• Make UI elements large enough to be easy to tap; place them far enough apart that there is little risk of tapping the wrong target by mistake.

• Eschew preferences as much as possible, and assume that nearly all users will use the default settings.

• As you show more detail, conceptually you move from left to right — but it’s best to minimize how deep you can get while drilling down to the right.
