App development services in London
We design and build iPhone, Android, TV and web apps for businesses and founders, along with the backends, payments and dashboards behind them. The same small team that makes our own apps works on yours, from first sketch to store release and the updates after.
Apps, websites and the systems behind them.
Pick one service or several. Most projects combine an app with a backend and payments, and we can take on all of it.

Proof we ship: our own apps.
We build and run our own products, so we carry the same costs and risks our clients do: store reviews, payments, support and updates.

Who we work with.
Based in London, working with clients across the UK, Europe and worldwide. Most work happens over video calls and shared documents, and we are happy to meet in person in London.
We work with start-up founders building a first product, and with established businesses adding an app, a TV channel app or a customer dashboard to what they already run.
How much does it cost to build an app in the UK?
It depends on the platforms, the number of screens and what the backend needs to do. After a short discovery call we send a fixed-price proposal with the scope written out, so you know the cost before any work starts.
How long does it take to build an app?
It depends on the scope: the platforms, the number of screens and what the backend needs to do. We agree the scope first, then fix the timeline in the proposal, so you know the release date before any work starts.
Do you build for both iPhone and Android?
Yes. We build native apps for each, in Swift for iPhone and iPad and in Kotlin for Android, sharing one backend and one account system so users get the same service on both.
Do I own the code and designs?
Yes. Once the project is paid in full, you own the code, designs and everything we built for you. We hand over the repositories, store accounts and documentation.
Do you work with clients outside London?
Yes. We are based in London and work with clients across the UK, Europe and worldwide. Most meetings happen on video calls, and we can meet in person in London.
Can you take over an app someone else built?
Yes. We start with a code review to understand the app and its risks, then agree a plan to fix, update or extend it, and look after it from there.
