What's harder for you: building a product or finding its first users?

I've been working on my own iOS side project alongside my full-time job.

As a developer, I thought building the app would be the hardest part. Turns out, getting people to discover it is an entirely different challenge.

I recently crossed 200 users, which feels like a pretty exciting milestone for something I started just for myself.

But now I'm realizing how much I still have to learn about distribution, marketing, and growing a product without a big budget.

For other indie makers here: what was harder for you — building your product or getting your first 100–200 users?

And what actually helped you get past that stage?
