Not to mention that the ONLY way to get an application into an iDevice is via
the Apple store. (At least if you don't expect end users to "jail-break" their
devices to allow downloads from "unauthorized" sources.) You can't just put
your app out for downloading on a site like SourceForge, TAPR.org, a Linux
repository or your own website.
Even if you want to give the application away for FREE to end users, it costs
the developer thousands of dollars in charges for specialized development
tools, yearly charges for access to the Apple Store, etc. And that's after you
pay to submit the app to Apple for approval before it goes live in the store,
with no certainty that it will be approved.
Charges like these are not too significant for mainstream consumer or business
apps that will sell a significant number of copies, but are a MAJOR obstacle to
low-budget part-time hobbyist-type developers in a niche field like APRS.
