I Have No Idea [Why Apple Featured My App]

In the case of Halftone, the quality of the app is excellent and has significant usage. There are 1100+ reviews that average to 4.5 stars. These numbers would be considered fantastic by any developer's standards.
I don't know just my 2 cents.
Apple wants you to build beautifully crafted user experiences. Google does too, but that is not their primary focus.
Side note: digging a little bit, here's a very useful library for converting SVG to UIBezierPaths: http://ponderwell.net/2011/05/converting-svg-paths-to-object...
Seems like such a powerful thing to be able to use more freely.
Anyone knows why that is? CPU, battery something else? (I am not a programmer)
As per resource usage, vector graphics actually use less disk space. Rendering requires more CPU than bitmaps, but I doubt it's something Apple couldn't handle with a warning in the documentation.
Most of the toolbar icons you see in Mail, Preview, Finder, etc. are actually PDFs that scale to any size.
The OP could have (and probably should have) used PDF for his vector-based graphics. And actually, by exporting raw CoreGraphics drawing functions from Illustrator he's essentially exporting a PDF document in a custom file format.
Somehow I knew the app wasn't going to be free after reading the article: "I just have no idea, except maybe that's it a really quality app [that you too can feature on you homescreen for just 99 cents]".
What I don't understand is why Apple wouldn't indicate why an app is featured - if for example high quality and innovation are prized then this should be lauded aloud to encourage others.
I made an image with the app just now: http://i44.tinypic.com/aua3ic.jpg
Review: 3 stars Good UX path on loading the app, guides you through steps. The designer of this app has done well to make a sensible interface, with only some work needed on the settings screen and the labeling choices there.
Replay value is another question. There's no sequencing layout tools or anything relating to more than the single image you're working on. Tools are not that powerful, but they do their job ok. It does one trick, and most people will probably use it one time.
Yep, the vector thing is pretty cool.
Now it just needs the ability to arrange and re-arrange multiple images, and swipe through them as a slideshow. Throw in a library of sound effects to assign each slide, with animated visual effects for little movie-making mobile graphic novels... and THEN it'd be a paid app worthy of promotion in my mind, but this is a good start.
