Seconding Overcast - it has traditionally traded blows with Pocket Casts as the best 3rd party podcast app on iOS, but I like it better for the smart speed and voice boosting features.
Overcast is continuing to go against the podcast industry grain by making privacy a distinguishing feature (https://marco.org/2018/04/27/overcast42). Good move. It's not useful to me as I have Android as well as iOS devices, but if I was Apple-locked, I'd be having a serious look at Overcast.
I agree overcast is miles ahead of pocketcasts.It protects privacy of the users, smart speed is awesome (removing silences and thus saving tons of time) and app is not laggy as pocketcasts was
