I prefer using built-in apps whenever possible, and it requires a significant functionality delta for me to switch to a third party option.
I just hit that escape velocity for my podcast application.
Apple’s redesign of the Podcast application wasn’t great for me. I tried to make it work, but the main competitor—Overcast—has simply become too compelling.
To get to your Smart Speed settings, open your full player view and swipe right.
I particularly like the black theme because it goes so well with the iPhone X in Space Grey, and I like my Smart Speed to be set to almost 2x for most things. Here’s a screenshot from mine just now.
If you’ve been unhappy with the native podcast app in iOS, but weren’t sure if you should switch, now might be the time. Overcast has enough better features to make it worth it.
