I don't believe he claimed he had zero sales from the beginning - just that he had zero sales for the last few days:
Unlike some people here, I agree that BlackBerry World needs a lot of work. Actually I think a lot of the mobile app stores need work.
And here is where the conflict of interest comes in: BlackBerry has in some cases corporate interests that conflict with developer interests. Case in point: app store owners always want their stores to appear "huge" and "full of variety". But the tactics used to create that impression often work directly against developers and users, making it in many cases very difficult to find the apps you want.
Specifically in regards to the example above: mapping and GPS apps. NINETY NINE PERCENT of that category is filled-up with page after page after page after page after page of so-called "apps" which are in fact just mapping data for a single town or city, for a single mapping app. THIS IS RIDICULOUS. Those stupid things completely swamp the other content in a category, or when trying to do a search for "GPS" or "maps" etc, making it completely useless trying to find something in that category.
Google Play suffers from a similiar problem, but I don't see the operators of these stores doing much about it because they are so addicted to the revenue from the "Top 40" apps, that all the rest are just basically fodder for them to bulk up the numbers. NONE of those stores actually have a good search function, as far as I'm concerned. And to be honest, I don't think they WANT to. They want people to constantly roll around in there amongst tens of thousands of things that aren't what they are looking for, trying to give the impression that if they didn't find the right thing, it must be the USER's fault, because, after all look at all those darn apps!!. :mad:
It's very similiar to the music industry: a few top headline acts get all the investment and all the promotion, and make 90% of the money, while most of the artists don't get enough in royalties to buy a cup of coffee.
My suggestion: Polish the app as per some of the suggestions here, then get some journalists to write about it, and it will stand out. EVERY SINGLE TIME I see a feature article about an app on Crackberry, that app rockets up to the top of the "top grossing apps" list. This tells me that the main issue is indeed, exposure. Especially if the app itself is decent.
I think creating this thread was an excellent first step, actually. Already a bunch of people are aware of your app that never knew it before. :)
Good luck.
