@Jean-YvesPochez what kind of sells boost can you expect from being published on the appstore ?
That's a million dollar question.
Unless Apple promote your application, it now goes straight into a black hole, where the only option you've got is either do marketing to promote your app outside of the App Store, directing traffic to the App Store, or you can pay Apple for search keywords, so that your application is guaranteed to come up when users search for it, because search is pretty much broken now.
All-in-all, for me at least, the App Store has been a complete waste of time these last few years, I do not have the resources to do effective marketing to get my app "noticed" in the sea of clones and copy cats, and quite frankly Apple's attitude where I've been rejected repeatedly for things that my competitors are allowed to do, just sours my enthusiasm for Apple and their stores even more.
@Mark C Absolutely. just wanted to check to see if there was already a simplified guide somewhere before doing that.
The main problem with this, is Apple change their design requirements as often as some people change their underwear. The App Store guidelines are published, but may be invalid tomorrow, and they're written losely, which makes it wide open to interpretation. Apple also do not provide a means for you to contact them and request if certain things can be done in a certain way, or even what's the best way to do task x so it doesn't violate any rules. Apple management knows how much of a problem this is, but have stated that they will not do this, because the guidelines change so frequently.
Start by selling on your own site, if you still want to be in the App Store, be prepared for it to be a nightmare, that way when it is, you're not too disappointed, and when it just goes through without a hitch or only requires minor changes, you'll be pleasantly surprised.
