Palm Pre App Catalog Total App Downloads Since Launch, via Medialets

That's impressive when you consider the fact that those millions application downloads can be attributed to just 150,000 Pres sold. That's an average of more than six app-downloads per device and 33,333 thousand total downloads per application, according to Medialets, with a download-low of 2,400 and a high of 114,000.

It's even more notable with some additional context. For example, the Palm Pre/webOS software developer's kit (SDK), dubbed Mojo, which provides developers with the tools necessary to create webOS apps, isn't even publically available yet. Developers using the Mojo SDK are participants in Palm's "early access program," and have likely signed away all sorts of freedoms in exchange for access to the tools. In other words, developers using the Mojo SDK for Pre are currently doing so according to a set of (strict) Palm rules.

Palm plans to release the SDK by the end of summer, but until then, it's up to the company who can and who cannot build Pre apps for distribution via App Catalog. Also developers who sign Palm's Mojo SDK non-disclosure agreement (NDS) can't talk about the SDK to anyone. They can't share feedback or best practices.

Furthermore, the App Catalog itself is still in "beta" testing stages, and as such, developers aren't yet allowed to charge for applications, according to Ed Finkler, creator of the popular Spaz Twitter application, which is available in Palm's App Catalog.

Finkler's currently offering Spaz for free via App Catalog, but he plans to eventually charge a small fee--from $1 to $3--to compensate folks who have contributed to Spaz, which is an open-source project. (Finkler will also make all pertinent Spaz for Pre source code available online, so it'll be free to those crafty enough to circumvent App Catalog.)

Such SDK and pricing restraints make it difficult, if not impossible, for independent developers like Finkler--who isn't funded by some large corporate entity--to sink time and resources into a Pre app because he and his fellow Spaz contributors aren't monetarily compensated in any way...yet.
