Mobile App Development in London, Built and Maintained

London runs on apps. From fintech startups in Shoreditch to retail brands in the West End, hospitality groups across Soho and logistics firms serving the M25, a well-built mobile app is often the difference between a customer who sticks and one who drifts to a competitor. But London agency quotes for a cross-platform app can be eye-watering, padded with account managers, project leads and layers you never actually speak to. That is exactly the model we sidestep.

We build iOS and Android apps, usually from a single cross-platform codebase, at a fixed price with everything included: hosting, developer accounts, security, ongoing updates and store submissions. You deal directly with the engineer writing your code, not a sales team relaying messages. That means faster decisions, no scope-creep surprises, and a product that actually launches. For London firms weighing a five-figure agency retainer against getting something live and earning, the maths is simple: half the cost, none of the middle-men, and a working app you own.

Mobile App Development in London — questions answered

Do you build separate apps for iPhone and Android in London?

Usually we build one cross-platform codebase that runs on both iOS and Android, which keeps your fixed price down and updates in sync. If your London business genuinely needs a fully native build for one platform, we will tell you honestly and price it accordingly.

What does the fixed price actually include?

Everything to get you live and keep you there: design, development, backend hosting, Apple and Google developer account setup, security, store submission and ongoing updates. There are no separate line items appearing later, which is the opposite of most London agency contracts.

Can you take on an app another London agency abandoned?

Yes, we regularly pick up half-finished projects. We audit the existing code, tell you plainly whether it is worth continuing or rebuilding, and quote a fixed price either way so you are never left guessing.

Will my app handle payments and Apple App Store rules?

We handle payment integration, whether card, subscription or in-app, and we know the App Store and Play Store review rules well enough to get you approved without weeks of back-and-forth rejections that stall a London launch.
