It’s hard to make a living selling a niche app to price sensitive people.
Also if it is a niche app, with a small addressable market, how do you continue making money on it since their is no facility for upgrade pricing - especially since you have to keep releasing updates to support newer devices and new screen sizes?
I've seen companies get around the upgrade pricing question by just releasing a new version of their app every year and deprecating the old one.
when i say it is a niche market i mean it not only in terms of number of customers, but also in term of potential generated revenues. there are businesses , especially in artistic fields, where people simply aren't willing to spend a lot of money on accessories, even if they are useful to their job.
now i'm not saying i will never be able to be profitable enough. just that with my current marketshare ( which is very good on a local scale, but not yet worldwide), those 30% are what makes the difference.
ps : as for the revenue model, i had to invent some kind of pay per use model, based on in app purchases.
I'm not an app developer, I'm in the music industry (day job in IT infra), but it seems to me there are some people projecting their bad business sense onto Apple. As per my other comment in this thread, and the reply someone made for me, the commission drops on subscription based apps, could you not use a subscription, rather than your pay-per-use system (which sounds like a creative workaround, kudos) and then you'll get the benefit of the tax rolloff.
Trying to make your own way in this world is damn hard work, and if a business model falls apart because one needs to "pay taxes," Apple will not be the biggest problem for very long. I'm sure most here would agree that it stinks that Apple are demanding a 30% tax whilst paying ~0% to the U.S. Government, but that is the way of things for now.
But, a niche product where people aren’t willing to spend money is a business model problem.
But do you know how many businesses would die to be able to sell products that had a 70% gross profit margin?
The only fixed cost imposed by Apple is the $100 developer fee and whatever it cost to buy a Mac.
The services provided by the App Store would have to be present for the business exist at all.
So without the 30% Apple charges those businesses would certainly not survive unless they paid someone else for the services.
