Web, Android and iOS app development

Apps your customers download from the App Store and Google Play, and web apps that run your business behind the scenes.

What you get

An app earns its place when customers use it again and again: to book, to order, to track something, or to reach you without a phone call. We start by working out what that repeat job is, so the app does one thing well before it does ten.

We build Android and iPhone apps from a single codebase, so you pay for one build and get both. Web apps and portals run in any browser with nothing to install. Every app comes with an admin dashboard, so you can manage users, orders and content yourself.

When it is ready, we publish it to the App Store and Google Play under your own accounts, and stay on for updates and fixes after launch.

Questions people ask

Do I need separate apps for Android and iPhone?

No. We build both from one codebase, so there is one project to pay for and maintain, and both versions get updates at the same time.

Who owns the app?

You do. The code, the App Store and Google Play accounts, and the hosting are all in your name.

How long does an app take?

A focused first version usually takes six to twelve weeks, depending on features. You get a written timeline with the quote.

Can you publish it to the stores for me?

Yes. We prepare the listing, screenshots and store details and handle the review process with Apple and Google.
