Ask HN: How would you grow a screen recording app after hitting $3.5K MRR?

Hey! I’m currently making $3.5K/month from a Mac screen recording app with zoom effects. It feels like I’ve hit a plateau and I’m not sure how to grow it further.

Most of my sales come from X and blog posts on my website. I’m trying to push both, but it takes a lot of time to see meaningful results.

Any non-obvious advice on how you’d grow something like this?
