It depends on your usage, for sure. For me, I’m more on the side of not seeing much there that’s valuable enough to subscribe to, though I’d probably pay a few bucks for the app just to support them. I think that if you’re happy with Google Podcasts, though, you’ll be happy with Pocket Casts without a subscription. It’s not like you have to pay for basic functionality, like downloading or queuing episodes, which is the evil version of the subscription model.
