iPhone: Overcast is one of the best podcast apps on iOS and now it's a lot better. Not only is it totally free, it also got a big update to add chapter support, more streaming options, and more.
Previously, Overcast locked away a few features behind an in-app paywall. Now, everything is free. That includes its smart speed option, voice boost, and cellular downloads. You can also finally now stream episodes instead of downloading them. Overcast also adds support for chapters, so you can easily jump through long podcasts.
