What Subject Should I Focus On When Making Software?

I'm a software developer who builds around my own interests: Wisecart came from a shopping-list problem, my boilerplate from rebuilding the same app foundations, and since early 2025 I've been posting on YouTube, which pushed me toward a new project focused on improving scripts. The problem is I'm not the most skilled developer, so a polished, competitive app isn't really my lane — so what should I actually focus on?

This is a common problem. Builders like Marc Louvion ship developer tools — Datafast, Shipfast — and do well, but a lot of that success comes from personal brand and community as much as the product itself, and those tools compete in crowded fields against the likes of Plausible or Google Analytics.

The way out is areas like finance, sports or productivity, where any competent developer can build something genuinely useful for a general audience instead of fighting for a sliver of a competitive niche. Finary is the example that stuck with me — a finance app I'd actually subscribe to, mostly because of how well its personal branding on YouTube built trust.

So my plan now is to bring my skills to low-competition areas — dressing, nutrition, productivity, motivation, personal management — not to avoid competition for its own sake, but to be early enough somewhere to actually make a difference. The bar stays the same either way: build something useful enough that I'd use it myself.
