According to a research report by Clammr (via RAIN News), podcasting is an increasingly mobile phenomenon with 82% of mobile listening happening on iOS. According to the report, Apple’s Podcasts app is also, by far, the most popular choice among users:

That means that of every 100 mobile podcast plays, 82 are on Apple devices, and 64 are in the Podcasts app, which is a carve-out of the Podcasts section in iTunes.

While I don’t doubt the overall accuracy of the report – by virtue of being a default choice on iOS, Apple’s Podcasts app is more than enough for most people – keep in mind that this report is based on a sample of RawVoice clients. These numbers are not, I assume, entirely representative of independent realities like Relay FM or shows such as The Talk Show and ATP, where the choice of clients tends to be more skewed towards alternatives such as Overcast.

Still, it makes sense for mobile podcast listening to be closely tied to iOS – Apple’s dominance with the iTunes directory and pre-installed Podcasts app must be playing a big role in that.
