App and software development
A London app and software development agency. We build apps and platforms that are still maintainable when the people who built them have moved on.
Building the thing you’ve been told is too complicated
We take on the awkward projects — the integration nobody wants to own, the rebuild that keeps getting deferred. You get working software in weeks, not a document about working software.
Our services include
App and web development
The thing your customers actually touch.
We build apps and websites that are quick, reliable and don’t fall over the week you get written about. That means proper foundations: search engines can read it, it works on a four-year-old phone, and when something does break you find out before your users tell you. You own the code and you can take it elsewhere.
Lean project management
Fewer meetings, more decisions.
We’d rather test an assumption in a fortnight than argue about it for a quarter. So we work in short cycles, put things in front of real users early, and change course when the evidence says to. You’ll always know what we’re working on, what it costs and what’s at risk. And you’ll hear about a problem when we spot it, not at the end of the month.
C-level advisory
A technical opinion with nothing to sell you.
Sometimes you need someone to read the proposal and tell you whether it’s reasonable. We do that — on hiring, architecture, what your roadmap will actually cost, and whether the quote in front of you is fair. Non-technical founders use us to ask the questions they’d rather not ask a supplier. Experienced teams use us for the opinion their own suppliers have an interest in not giving.
What’s included
App and software development, from plan to launch
One team covers the plan, the design, the build and what happens after launch, so you don’t have to stitch suppliers together.

Featured work

App development questions
Are you a UK app development agency?
Yes. Contic is a UK product team based in London, and we design, build and look after apps and software for founders, scale-ups and the public sector across the UK. You work with the people building your product, not a sales layer.
How much does app development cost in the UK?
It depends on the scope. Our LaunchPad packages run from £25k to £100k at a fixed price, covering design, build, infrastructure and launch. Larger platforms are priced after Discovery. Our guide to app development costs in the UK breaks the numbers down. For a quick range, try our app cost estimator.
How long does it take to build an app?
Most first versions launch in two to four months through LaunchPad. Larger platforms take longer, and we agree the timeline alongside the price once Discovery is done.
Do we own the code?
Yes, the code and the IP. During the build, developer accounts, hosting and the repository sit with us or with you, whichever you prefer. They’re yours at launch either way.
Can you take over an app another agency built?
Yes. We took over Electragram’s platform from a previous supplier mid-season and kept live events running. We start with a review of the code, so you know what you have before we build on it. Here’s how a takeover works.
Do you build for iPhone and Android?
Yes, from one codebase, tested on both. Websites work on current versions of Chrome, Safari, Firefox and Edge.
What happens after launch?
TotalCare looks after hosting, app store accounts, third-party services and support for a fixed monthly price. We agree it before the build starts, so there are no surprises.
Got something that needs building?
Tell us what it has to do and who it’s for. We’ll give you an honest view of the scope, the price and where to start.
