Almost a year ago, I linked to Lee Robinson’s essay “Personal Software” and later explored why we need a HyperCard for the AI era. The thesis: people would stop searching the App Store and start building what they need. Disposable tools for personal problems.

That future is arriving. Dominic-Madori Davis, writing for TechCrunch, documents the trend:

It is a new era of app creation that is sometimes called micro apps, personal apps, or fleeting apps because they are intended to be used only by the creator (or the creator plus a select few other people) and only for as long as the creator wants to keep the app. They are not intended for wide distribution or sale.

What I find compelling here is the word “fleeting.” We’ve been conditioned to think of software as permanent infrastructure—something you buy, maintain, and eventually migrate away from. But these micro apps are disposable by design. One founder built a gaming app for his family to play over the holidays, then shut it down when vacation ended. That’s not a failed product. That’s software that did exactly what it needed to do.

Howard University professor Legand L. Burge III frames it well:

It’s similar to how trends on social media appear and then fade away. But now, [it’s] software itself.

The examples in the piece range from practical (an allergy tracker, a parking ticket auto-payer) to whimsical (a “vice tracker” for monitoring weekend hookah consumption). But the one that stuck with me was the software engineer who built his friend a heart palpitation logger so she could show her doctor her symptoms. That’s software as a favor. Software as care.

Christina Melas-Kyriazi from Bain Capital Ventures offers what I think is the most useful framing:

It’s really going to fill the gap between the spreadsheet and a full-fledged product.

This is exactly right. For years, spreadsheets have been the place where non-developers build their own tools—janky, functional, held together with VLOOKUP formulas and conditional formatting. Micro apps are the evolution of that impulse, but with real interfaces and actual logic.

The quality concerns are real—bugs, security flaws, apps that only their creator can debug. But for personal tools that handle personal problems, “good enough for one” is genuinely good enough.
