Don't use Fountain but this is the way. I've long refused to have my nsec anywhere else but in Amber.

What’s wrong with fountain?
It's closed source, buggy, constantly crashing and relies on a custodial bank to do v4v.
AntennaPod is superior in every way. It does not have v4v, it's just a minimal podcast app, but you can always zap/donate to podcasters directly without Fountian taking a middleman fee.
