About

A small London company that makes its own apps.

YYY Software Ltd is a London company, filed at Companies House in England and Wales. We make our own apps for iPhone and Android: nobody commissions them, and nobody else’s name goes on them. Below: what gets made, how one thing is chosen over another, and the number to check us against.

The rest of this page is method: how an idea earns a build, and how a build earns a place on somebody’s phone.

What the company is

A product company, not a services vendor.

The apps are ours. Nobody commissions them, nobody signs off a scope, and there are no hours to buy. Anyone who arrived here hunting for an agency to build their app has the wrong company, and it seemed fairer to put that near the top than to spend twenty minutes of a call getting there.

A person sitting sideways on a window seat in a plain flat, framed below the shoulders, holding a phone with a dark screen loosely on one knee. — The test for a consumer app is whether it survives a dull Tuesday, not a demo.

A communal stairwell in a British block of flats, worn stone steps and a painted handrail with one hand entering at the top of the frame. — London is where the company is registered and where the work is done.

How we work

Method, described plainly.

An idea has to survive one sentence

Before anything is drawn, an idea is written as a single sentence that a person outside the company would understand without a preamble. If the sentence needs a second one to make sense, the idea goes back.

Design and engineering are the same conversation

The same small team draws the screens and writes the code, so a decision made in a sketch is not renegotiated in a ticket. The practical effect is that the thing that ships is the thing that was drawn.

The first build is deliberately narrow

The first build exists to be carried around for a week of ordinary days. It is judged on whether it gets used when nobody is watching, not on whether it demonstrates well.

Abandoning is part of the method

Most ideas do not survive that week, and we say so when one is dropped rather than leave it implied. Saying so keeps the list of live work short enough to mean something.

Data stays on the device by default

Some features cannot work without a server. When one of ours does, the screen doing the sending spells that out on the spot, and the privacy notice repeats it in the same plain words rather than a legal paraphrase.

On the name

YYY, three letters, one word.

There are other companies on the register with similar names, and there are unrelated software firms in the United States trading under names built from the same letters. We are none of them. Our name is written as one word, YYY, and never shortened, so the company number below is the safest way to be sure which company you are looking at.

That is the most useful thing anyone sends us, and it is the same address for questions about the company, the method, or a sentence on this page that reads wrong.
