Why building internal, personal apps is the future of software

For most of software's history, building an app was expensive enough that it only made sense to build things lots of people would use. You needed a team, months of time, and a market big enough to justify the cost. So we all ended up using the same handful of generic tools, bending our actual workflows to fit whatever the product manager at some company decided was 'the' way to do it. That constraint is quietly disappearing.

The cost of building just collapsed

With modern tooling and AI, the time it takes to go from 'I wish a tool did X' to a working app has dropped from months to, sometimes, an afternoon. When building gets that cheap, the math changes completely. An app no longer needs a market of a million people to be worth making. It can have a market of one — you — and still be absolutely worth it.

When software costs almost nothing to build, it stops needing to be for everyone. It just needs to be exactly right for someone.

Generic software is a compromise

Every mass-market tool is the average of a million different needs. It has features you'll never touch, is missing the one thing you actually want, and forces you into someone else's idea of the 'right' workflow. We've been so used to that compromise that we stopped noticing it. A personal app has no such tax — it does your job, your way, and nothing else.

• No features you don't use cluttering the screen
• Built around your workflow, not a committee's
• Your data, your rules, no subscription creep
• Changes the moment your needs change

What 'internal and personal' actually looks like

It's the small tracker for the exact metrics you care about. The dashboard that pulls together the three tools you check every morning. The little automation that handles the repetitive task nobody else has, because nobody else has your particular job. Individually these feel too small to ever be 'real' products — and that's precisely the point. They were never meant to be products. They're tools.

I've felt this shift in my own work. A lot of what I build now started as something I made for myself or for one specific client's odd workflow — too niche to ever ship to a mass market, but genuinely better for the person using it than any off-the-shelf option. The best software increasingly isn't bought; it's built to fit.

Why this is the future, not a fad

Software has always trended toward whatever the cost of building allows. When it was expensive, we got monolithic apps for the masses. As it gets cheap, we get a long tail of small, sharp, personal tools — software shaped to the person instead of the person shaped to the software. That's not a downgrade from 'real' apps. It's what software was always supposed to be once we could finally afford it.

The future of software isn't fewer, bigger apps. It's millions of small ones, each built for exactly one situation.

If there's a tool you keep wishing existed — for you, your team, or your business — that wish is now a perfectly good starting point. Tell me about it, and let's build the version that fits you exactly.
