My app made $250 last month, how do I market it correctly?

I made PodBuddy, an iOS app that allows podcasters to create animated videos from their audio clips, to share on social media.

I've always wanted to make an editor app (of any kind), and I saw an opportunity to make one where podcasters could add waveform animations, progress parts, etc..

I've so far received good feedback from podcasters, and some are using it constantly to create posts and stories for their podcast.

But when I compare it to larger competitors (Wavve or Headliner), the revenue PodBuddy is making at the moment is negligible. I wonder how they nailed the marketing game.

So far it has been tough even getting podcasters to download it (I'm trying Apple Search Ads and Reddit ads), let alone convert them to paying customers.

I know I have a more intuitive product, and I know it's a winner. I just don't know how to market it (yet).
