App developers for first-class iOS and Android apps
Native and cross-platform apps that feel right on the device and are built to survive real use.
How much does app development cost in the UK?
A simple app with a few screens and a basic backend typically starts around £6,000 to £15,000 in the UK. Apps with accounts, payments, real-time features and admin dashboards usually cost £20,000 to £60,000 or more. Devute's mobile app development starts at £6,500, with a fixed quote after a free audit.
We design, build and launch iOS and Android apps — consumer products and internal tools alike — with the backend, analytics and store compliance handled.
Consumer-app founders and businesses that need field, internal or customer-facing mobile tools.
What Mobile Apps covers.
iOS & Android
Native where it counts, cross-platform (React Native / Flutter) where it makes sense.
App UX & prototyping
Interfaces designed for thumbs, offline states and real-world conditions.
Backend & APIs
The services your app depends on, built to scale with it.
Store launch & compliance
App Store and Play submission, review and release handled for you.
Maintenance & analytics
Ongoing updates plus the analytics to see how the app is actually used.
Native, cross-platform or web app?
| Native (Swift / Kotlin) | Cross-platform (React Native / Flutter) | Progressive web app | |
|---|---|---|---|
| Cost | Highest: two codebases | Lower: one codebase | Lowest |
| Performance | Best | Very good for most apps | Good |
| App Store presence | Yes | Yes | No (installs from the browser) |
| Device features | All | Nearly all | Limited |
| Best for | Heavy graphics, deep device use | Most business and consumer apps | Internal tools, quick launches |
No quotes theatre. Four steps.
You get an indicative range before discovery and a fixed scope after it. Nothing about the price should be a surprise.

How much does it cost to build an app in the UK?
Simple apps typically start around £6,000 to £15,000, while apps with accounts, payments and admin dashboards usually cost £20,000 to £60,000 or more. Devute's app development starts at £6,500. You get a fixed quote after a free audit, so you know the cost before work starts.
How long does it take to develop an app?
A focused first version usually takes eight to twelve weeks, from design to App Store and Google Play launch. Smaller internal tools can be quicker. We release in stages and you test working builds on your own phone throughout.
Do you build for iOS and Android?
Yes. Most clients get one cross-platform codebase in React Native, which runs on both iPhone and Android and keeps costs down. We build fully native apps when performance or device features need it.
Will you publish the app to the App Store and Google Play?
Yes. We prepare the store listings, screenshots, privacy details and review submissions, and handle any feedback from Apple or Google until the app is live.
Do I own the app and its code?
Yes. You own the source code, designs and accounts. The app is published under your developer accounts, and we hand over documentation so any competent team could continue the work.
Can you build the backend and admin dashboard too?
Yes. We build the APIs, database, user management and the admin dashboard your team uses, and host them on reliable cloud infrastructure.
What happens after the app launches?
We offer maintenance plans covering OS updates, crash monitoring, security patches and small improvements, or a retained team for ongoing features. Phones update every year, so apps need regular care.
