XOJO.CONNECT Designing a beautiful iOS App

During this session at XOJO.CONNECT I will demonstrate how to create a nice and appealing looking app.
Having a nice UI is very important in both business and consumer apps, especially on mobile.

I am thinking of either showing a dummy app and how to improve the design, or using an existing app from one of the attendees.
If one of you has an iOS app that needs a big design overhaul, feel free to post a link to the app and I might select it for the session.

Nice idea. But for a pleasant speech, maybe better prepare a bad app yourself and apply the steps needed to make it nice.
