37 apps since 2008. Why no hit?

PayDown is the 37th mobile app I've built since 2008. My first — a vacation countdown widget — sold about 2,000 copies and is still on the Play Store. None of the thirty-seven ever really took off, and mid-build I finally asked the question out loud: why can't I make an app that makes money?

The answer I got back from Claude was uncomfortable because it was true, so I'm publishing it where I can't un-see it:

Building was never the problem. Thirty-seven shipped apps in eighteen years is an elite shipping record. But each one got months of engineering and roughly zero sustained distribution. That's not bad luck thirty-seven times; it's the same allocation decision thirty-seven times.

There's no guaranteed money on the App Store. What exists instead: a niche with real pain (BNPL sprawl qualifies), a product that solves it honestly (this one does), and then the part I've always skipped — showing up in public every single week. A post, a video, a build log, an answer in a community. Boring, repeatable, compounding.

So that's the standing rule now: from beta onward, every week ships one marketing artifact alongside the code. This post is one. This whole blog is the enforcement mechanism.
