iPhone Programmer Profiles and Endorsements

Tuesday, December 9th, 2008

I’ve just launched Mobile Orchard Profiles, a wiki-like site featuring profiles and endorsements of iPhone developers.

The launch announcement covers the details. I’ll summarize here:

It’s hard to prove you’re a capable developer in a brand-new tech. Nobody’s got years of experience or a deep showcase of examples to point to. The site help show credibility by letting developers endorse other developers. Being in good company is a great way to be credible!

Update: as of right now, the site’s #3 on Hacker News

Podcast Interviews: Decoding iPod Backups, Calculating The Temp By Listening To Crickets?!?

Sunday, December 7th, 2008

I posted a pair of interviews to the Mobile Orchard Podcast:


The first interview is with Padraig Kennedy, author of a very useful iPhone/iPod Touch backup decoder.

The second interview is with Pete Schwamb, creator of an app that can tell you the temperature by analyzing the sounds of crickets chirping.

iPhone App Economics

Tuesday, December 2nd, 2008

There’s been a lot of talk about pricing iPhone applications.

I was curious about correlating price and popularity within product categories. Peter Cooper thought it’d probably follow a Zipf-like distribution, with more expensive apps falling off quickly.


(see article for larger graph)

Turns out, it kind of does and it kind of doesn’t. By and large, cheaper apps are more popular. That said, in every category there are exceptions: there are apps that are way more popular than they should be for their price. Can better apps fetch more?

While working on this, I started experimenting with combining price and popularity. Multiply them together and you should get a relative ranking of who is making the most, the second most, etc. You can’t get absolute numbers, but as a relative gauge it’s interesting.

Anyway, we’re working on a series of articles about this that’ll be posted to Mobile Orchard. The first one, Price and Popularity: The iPhone App Store’s Data Show Who’s Making The Most Money, went up today.
