For reference, for the people saying I shouldn't raise my price:

Pocket Casts: $40/year
The Podcast App: $37/year
Castbox: $35/year
Castro: $25/year
…
Overcast: $10/year

I have no problem telling everyone this now: I'm raising my price in the near future.

I've only waited this long because I wanted to give you some new stuff at the same time!
