Link: SkyBuilder (NON affiliate link)
So far i'm actually VERY impressed with this one, I've already built one app and I will be submitting it to the apple AND android app marketplaces this coming weekend when I have a little free time to focus on that. :-)
Price points at $147 per month OR $1000 per year (which saves you $800).
You can make FREE apps and monetize via admob etc AND you can make apps for small local businesses and sell them for a flat fee AND/OR monthly maintenance fee
It's expensive, BUT i do recommend it.
I've got a few video reviews, but I can't throw them up due to affiliate links - but regardless - buy this - make apps - make money.
