App & software development

Apps and web systems, built properly.

iPhone and Android apps, the office systems behind them, and the servers, payments and integrations that hold it all together. Designed with the people who’ll use it, built by one small team, and looked after for years.

What we build

Everything an app needs, under one roof.

The phone app, the office system behind it, the server, the payments and the joins to everything else. One team builds all of it, so nothing falls between two suppliers.

iPhone and Android apps

One codebase, both app stores. Apps your customers and your team actually open, with notifications that arrive when they matter.

Web systems and dashboards

The office side: bookings, rotas, timesheets and reports, in any browser. Nothing to install, nothing to update.

Works with no signal

Saves on the device and syncs when it can. For boats, building sites and fields.

Payments, servers and integrations

The back end and the API, card payments and Apple Pay, SMS, email, Google, and the systems you already run.

Hosted and looked after

We host it, keep it updated and backed up, and stay on hand. The people who built it are the people who support it.

How we work

From a sketch to the App Store.

Scroll to watch an app come together, the way ours do.

  1. 01Sketch

    It starts with the job, not the tech. We sit down with you, and the people who’ll use it, and sketch what they actually need.

  2. 02Design

    The sketch becomes screens you can tap through. We change them until they feel obvious.

  3. 03Build

    Then we build it properly: the app, the server behind it and the joins to everything else.

  4. 04Launch

    We publish it to the App Store, Google Play and the web, then keep it running and keep making it better.

Our own products

Proof, not promises.

We build, sell and support software of our own, used every day by restaurants, fire stations, rescue teams and engineering firms. Yours gets the same care.

Questions

Questions people ask about app development

Do you build for both iPhone and Android?

Yes. We build one app that runs on iPhone, iPad and Android from the same code, and usually a web version for the office too, so there is one thing to maintain rather than three.

Can the app work without a signal?

Yes. Our apps can save everything on the device and send it on when they are back in range. DayBoat works that way at sea and SiteNotes on survey sites with no coverage.

Can it connect to the systems we already use?

Usually. We build the server and the API behind each app, and connect it to card payments, Apple Pay and Google Pay, SMS, email, Google and other systems through their own interfaces.

Who looks after the app once it is live?

We do. We publish it to the App Store and Google Play, host the server side, keep it updated and backed up, and stay on hand when something needs changing. The people who built it are the people who support it.

Do you only work with businesses in Cornwall?

No. We are based in St Issey, Cornwall, and work with businesses anywhere. Our products are used by restaurants, fire stations, rescue teams and engineering firms across the UK.
