About Us

If you need an app, we're your go-to team

Complete and transparent project plans
Brilliant talent pool - in house and remote
Public-facing, internal, games, stores... and more

We can give you total app development following a project plan designed to make your idea work. We have loads of experience creating a multitude of apps. So we can entertain your fans with mobile games, streamline your sales with a mobile store or generate income from your content with in-app purchases.

Alongside incredible apps for customers, we also make apps for inside your business - internal management, booking systems, payment, point of sale and even TV game show control systems. Let’s chat and we’ll work out how to build an app that works for your organisation.

Our tech heads love to use the very latest app programming technology too. We design apps that work on iOS and Android using robust programming systems such as Flutter, React Native, Unity plus loads of up-to-the-minute tools to wow your customers, audience, whoever!

Built from scratch. Kept running smoothly.

Each project built from scratch
Integrated analytics tools
Expert support and maintenance

To give you complete control, we’ll connect your app to a bespoke content management system which makes updates a piece of cake. You can also reach out to new customers by using powerful built-in analytics tools and trade securely with super-safe data processing.

Naturally, our in-house development team takes care of absolutely everything - app design, coding, installation and maintenance. Standing by, we have our remote experts for larger projects or when we need specialist help.

Once your app is up and running, we’ll keep it working in great condition. We’ll submit it to app stores, look after updates and generally keep an eye on things to guarantee your customers always get a great experience using it.

How much does it cost?
Transparent and fair pricing

As we’re a small team (not a big agency) with few overheads, we can offer our clients exceptional value.

We love working on projects of all sizes, whether they take a day or weeks and weeks. So we charge a ‘per-project fee’for each deliverable produced, agreed at the start of a project by looking at the hours and resources needed.

Current industry rate guides set our hourly rates, so you can be sure to get the best cost performance.
