Services

Four lines of work, all of them things this company does itself. Each one is also how our own apps get built, so the methods are not borrowed.

Software development

iOS and macOS applications, from the first sketch to a build that passes App Review and keeps passing. Native Swift and React Native, offline-first data, StoreKit purchases, and the release plumbing around them.

AI applications

Language-model features that do a specific job inside a product: classification, summarising, generation, speech. Built behind a server-side key with a rate limit, never with an API key shipped inside the app.

Digital content

Short video, store screenshots, listing copy and the assets a launch needs — produced as a repeatable pipeline rather than a folder of one-off files.

Advertising design and placement

Creative for a campaign and the running of it: design, production, placement and the reporting that says whether it worked.

How the work runs

One point of accountability

The person who scopes the work is the person who does it. Nothing is handed to a team you never meet.

Measured, not asserted

Load time, contrast, memory ceilings, battery — anything that can be measured is measured before it is claimed. The engineering notes on this site are written the same way.

Yours at the end

Source, assets and store accounts belong to you. No part of the work is locked to us.
