Mobile applications

Apps designed for the phone first.

We design and build phone-first products, from companion apps to standalone tools.

Photonnic, a private photo diary that keeps its data on the device, is one we built as an installable web app. The right approach for your product is chosen with you, based on what it needs to do.

Problems this solves

The situations that usually bring people to this service.

  • Customers or staff do most of their work on a phone, and the current tool was made for a desktop.
  • An idea needs a first working version before it is worth a larger build.
  • Data needs to stay on the device, or the app needs to keep working without a connection.

What is included

The scope is agreed with you in planning. Not every project needs every item.

  • Product and screen design

    Screens designed for small displays and one-handed use before any code is written.

  • Build for the approach you choose

    An installable web app, as with Photonnic, or another route agreed in planning. The choice follows the product's needs.

  • On-device storage and offline use

    Where the product needs it, data stays on the phone and the app keeps working without a connection.

  • Testing and release

    Tested on real phones where we can, then released and handed over with documentation.

Technology

Chosen to fit the problem, not the other way round.

  • Installable web app (PWA)
  • IndexedDB
  • Vite

How we work

A typical engagement. Not every project needs every step.

  1. Discover

    Understand the business, users, goals and constraints before anyone opens a design tool or an editor.

  2. Plan

    Define information architecture, scope, functionality and the technical direction.

  3. Design

    Interfaces designed to be built, not reinterpreted by whoever picks up the file next.

  4. Build

    The stack the product actually calls for: Laravel, React, Next.js or WordPress.

  5. Refine

    Test, optimise, correct and polish before anything ships.

  6. Launch

    Deployed and verified in production, ready for handover.

  7. Hand-off

    Documentation, credentials and a walkthrough, so nothing stays as knowledge only we hold.

Questions

Straight answers to the usual ones.

Will it be a native app or a web app?

We decide this with you in planning, based on what the product has to do and who will use it. Photonnic is an installable web app; other products may call for a different route.

Can you build a first version to test an idea?

Yes. A first version with a small set of screens is a common way to learn whether an idea works before committing to more.

Tell us what you need built.

Describe what you need. We will tell you what we would do and what we still need to know.
