App developers in London

App development for London startups and businesses

From our base in East Ham, we design and build mobile apps for startups and businesses across London and the UK: booking and appointment apps, ordering and delivery apps, membership and loyalty apps, and tools that connect to the systems you already use.

We help you shape the idea before any code is written: who the app is for, which features matter at launch, and whether a cross-platform build with Flutter or React Native or a native build is the better investment. Then we design, build, test and publish to the App Store and Google Play, and stay on for updates.

Pricing

What affects the cost of an app?

Every app is quoted individually. These are the decisions that have the biggest effect on the budget.

Features and screens

Each extra user journey — sign-up, payments, chat, maps, notifications — adds design, build and testing time.

Platforms

iOS, Android or both, and whether one cross-platform codebase or two native apps is the right fit.

Backend and integrations

User accounts, an admin dashboard, payment providers and links to your existing systems or APIs.

Design

A polished, custom interface with animation takes longer than a simple, standard layout.

Running costs

App store developer accounts, hosting, and maintenance to keep up with new iOS and Android versions.

Every project is quoted individually after a free consultation, with a clear quote within 24 hours. Get your free quoteRead our guide: how much does it cost to build an app in the UK?

FAQ

App development questions

Do you develop apps for both Android and iOS?

Yes. We offer native development as well as cross-platform solutions using Flutter and React Native, so we can deliver high-performance apps for both platforms with consistent design and functionality.

How long does it take to develop a mobile app?

It depends on the complexity of the app. Simple apps take 2–3 months, while complex applications can take 4–6 months or more.

Can you integrate payment gateways and third-party APIs?

Absolutely. We integrate popular payment gateways such as Stripe and PayPal, and handle third-party API integrations for shipping, inventory management, analytics, social login and more.

Do you offer app maintenance and updates?

Yes. We offer post-launch support including bug fixes, performance optimisation, OS update compatibility and new feature additions.

How much does it cost to build an app in London?

It depends on the features, the platforms, the backend and integrations, and the design. We do not publish a price list: after a free strategy call we send a clear quote, and we can suggest a smaller first version (an MVP) to keep launch costs down.

Should I choose Flutter, React Native or native development?

Cross-platform frameworks such as Flutter and React Native let one codebase run on iOS and Android, which usually saves time and budget. Native development can suit apps that lean heavily on device features or need the very highest performance. We recommend an approach after understanding your app.

Can you build an MVP first?

Yes. Starting with a minimum viable product — the smallest version that solves the core problem for your users — is often the smartest way to test demand before investing in the full feature list.

Will you publish my app to the App Store and Google Play?

Yes. We prepare the store listings and builds and handle the submission and review process, then publish your app and support it after launch.

Do you only work with businesses in London?

No. We are based in East Ham, London, and work with startups and businesses across the UK. Strategy calls and progress updates run over video call.
