Work with us

We also build for other people.

Most of what we do is our own apps. The rest of the time we take on work for other people — the same way, with the same standards.

You talk to the person who writes the code. There is no account manager in the middle, no team you never meet, and nothing gets subcontracted to someone we have not worked with.

We take on a few projects at a time on purpose. It is the only way to finish something properly, and it means that if we say yes, you have our attention.

What we do

iPhone and iPad apps

Native, written in Swift for Apple’s own frameworks — not a website in a wrapper. From the first sketch to the app being live on the App Store, including the parts nobody enjoys: review, privacy policies, screenshots and store listings.

Websites

Fast, readable on a phone, and built to keep working. No cookie banner, no tracking scripts and nothing loaded from a third party unless you ask for it. The site you are reading is one of ours.

Design and identity

Interface design, a logo and colours that survive being shrunk to 22 pixels, and the App Store artwork that decides whether anyone taps install. We design what we build, so it does not get lost between two suppliers.

Fixing what already exists

An app that got rejected, a site that is slow, a launch that stalled. Sometimes the useful job is not a rewrite: it is finding the one thing that is blocking you and getting it out of the way.

Our own work

Three apps designed, written and prepared for the App Store end to end — interface, code, icon, screenshots and store listing. The same work we would do for you.

This site is ours too. It is generated from a data file, it works in two languages, and it loads nothing from anybody else — no fonts, no analytics, no trackers.

How it works

  1. Tell us what you need

    An email is enough. What it is for, roughly when you need it, and anything you already have — sketches, a document, a half-finished project.

  2. We tell you what we think

    Within a couple of business days, honestly: what we would build, what we would leave out, and whether we are the right people for it. If we are not, we will say so.

  3. A fixed scope and a price

    Before anything starts, in writing. You know what you are getting and what it costs, and you see it working as it is built, not at the end.

Tell us what you need

Write to [email protected] with a couple of lines about the project. A person reads it and a person answers — usually within two business days.

We work in English and Spanish, and we are based in the United States. Everything we build is yours: you get the source code, the accounts stay in your name, and you are never locked into us to keep it running.
