Web apps, mobile apps & business software

App development in Hampshire, built around how you work

Off-the-shelf software makes you work its way. We build the thing you actually need, whether that’s a web app your customers log into, a tool to replace the spreadsheet everyone hates, or an app for the one job nobody else has built properly. We’re based in Eastleigh and work with businesses across the UK, and you deal directly with the people writing the code.

What we build

Software that fits the business

Most of what we build falls into one of these. If yours doesn’t, say so and we’ll tell you honestly whether we’re the right fit for it.

Customer-facing web apps

Accounts, logins, dashboards and payments, so your customers can sort things out themselves instead of ringing you.

Apps that install like native

They sit on the home screen, work offline and send push notifications, for roughly half the cost of building the same thing twice for two app stores.

Replacing the spreadsheet

That shared file three people edit and nobody trusts, turned into a proper system with records, permissions and an audit trail.

Booking, quoting and invoicing

We already run these for our own clients, so the hard parts are sorted: reminders, deposits, card payments and chasing late payers.

Joining systems together

Your accounts package, payment provider and supplier feed, connected up so nobody has to type the same thing in twice.

Internal tools for your team

Job boards, stock, route planning and reporting, built for the handful of people who use them all day.

Fixing what you already have

An app someone built and abandoned, or one that nearly works. We’ll take it on if it can be saved, and tell you straight if it can’t.

The code stays yours

At the end you get the repository and the deployment. There’s no licence or lock-in, and you don’t have to keep us on afterwards.

How it runs

Built and paid for in phases

Software projects tend to go wrong when everything is agreed and paid for up front. We split the work into phases, price each one, and you pay when a phase is finished and working. If you want to stop after phase one, you can, and you keep what’s been built. Need a website instead, or as well? Sites are £10 a month, and bespoke tools sit somewhere between the two.

Tell us what you need building

Send us a few details and we'll get back to you. If you need a website too, we'll include a free demo of what it could look like, and it's yours to keep.
