Apps

Native iPhone apps, web apps, and small custom tools for jobs that off-the-shelf software does not cover.

An app is a much bigger job than a website. It takes far longer to build, and the first conversation is about whether an app is the right answer at all. Often it is not.

What it is

Software built for one job. That might be an app on a phone, or a small tool that runs on a computer in your office. We build the first version around the thing you actually need, get it into your hands, and add to it once you have used it for real.

Who it's for

These are custom apps for a business's own use, or for one person's own work. A business that wants its own tool for scheduling, checklists, or records, on the phones its staff already carry. A small operation copying the same numbers between a paper form and a spreadsheet every week. Someone whose own routine needs a tool that no off-the-shelf app covers.

What you get

  • The app itself, built the way you choose below.
  • Working builds you can try while it is being made.
  • The finished app running on your own device before it is published.
  • A handover covering how to run it and what it costs to keep.

Three ways to have it built

A web app
It runs in the browser on any phone or computer. There is no Apple developer account to hold, and it is the simplest way to own your app outright.
A native iPhone app under your Apple developer account
You hold the account, the listing, and the app. We build it and hand it over.
A native iPhone app under our developer account
We publish it, keep it updated, and deal with Apple. That ongoing work is an additional cost, quoted in the plan.

Which one fits is part of the first conversation, and who owns what is agreed in writing.

Our own apps, in development

  • A golf app for iPhone: GPS caddie, score tracking, game modes for playing with friends, and automatic course mapping so you can play courses nobody has mapped by hand.

  • A desktop control room for running many AI coding agents in one window.

  • DiscOff

    A disc golf companion app.

How it works

  1. You send a message describing the idea or the problem.
  2. We talk through what the app has to do, and what it does not need to do yet.
  3. You get a written plan for the first version, and a quote, before any work starts.
  4. We build it, and you try working versions along the way rather than at the end.

What we don't do

We do not guarantee App Store approval. Apple and Google review every app against their own rules and can reject or hold one. We do not commit to a launch date, because that review sits outside our control.

We also do not take on games, or apps that depend on custom artwork, animation or illustration. Those need a designer or an illustrator rather than the kind of work we do.

Questions we get asked

Who owns the app?
It depends which of the three ways above you choose. Each one says who ends up holding the app.
Do you build for Android?
Not at the moment. We build native apps for iPhone, and web apps that run anywhere.
Who pays the app store fee?
Apple charges a yearly developer fee. Whoever publishes the app pays it, and the plan says which of us that is.
Can you take over an app somebody else started?
Sometimes. It depends on how it was built and what state the code is in. We look first and tell you whether carrying on or starting again works out cheaper.
What if I only have an idea?
That is the normal starting point. The first conversation is about turning the idea into something with a shape, and it ends in a written plan you can decide on.
What happens after it launches?
Changes after launch are quoted as they come up.
