How long does a mobile app take to build?

A focused first version typically takes 6 to 12 weeks. Complex apps with backend systems take 3 to 12 months. We launched a live streaming app on iOS and Android within 3 months for The World Games.

Do you build for both iOS and Android?

Yes. We build native apps in Swift and Kotlin, and cross-platform apps in React Native and Expo when one codebase makes better commercial sense.

Do you offer support after launch?

Yes. We provide 24/7 monitoring, bug fixes, performance optimisation and feature updates under an ongoing support agreement.

Will my app be GDPR compliant?

Yes. We design data handling around UK GDPR from the start, and we are ISO 27001 and Cyber Essentials certified.

Do you handle the app store submissions?

Yes, both stores, including the review cycles. We prepare listings, screenshots and compliance details, and we handle rejections if they happen so launch dates hold.

BUILD PHASEFOR PRODUCT OWNERS GOING MOBILE

Mobile apps that make it to the store, and keep working after.

Q: Native or cross-platform: which will you recommend?

Whichever the evidence supports. Native Swift and Kotlin when performance or platform features demand it, React Native or Expo when one codebase makes commercial sense. We show you the reasoning before you choose.

We design and build iOS and Android apps for clients in the UK and internationally: native Swift and Kotlin when performance demands it, React Native or Expo when one codebase makes commercial sense. A focused first version takes 6 to 12 weeks.

Where app projects go wrong

An idea with no route to the storeYou know what the app should do, not how it ships. Between the idea and the App Store sit a hundred decisions you should not have to make alone.

An agency that vanishedAn app in the stores and nobody maintaining it. Each OS update is a small gamble, and the reviews record every crash.

Web-only when users are mobileYour customers are on phones; your product is not. Every mobile visit to a desktop experience is a quiet apology to your users.

Two codebases, twice the costSeparate iOS and Android teams burning budget. Two codebases mean every feature is built twice and fixed twice.

Worked example

How an app project runs, start to finish

Drawn from The World Games streaming apps: iOS and Android, delivered alongside the web platform in three months

01A deadline that could not moveThe games had a start date. Web, iOS and Android apps were scoped to ship together, in twelve weeks.

02Streaming-first designLive video, schedules and results built around the moments fans actually use mid-event, on stadium wifi.

03Both stores, first passApple and Google review requirements designed in from the start, so approval came without resubmission loops.

04Live through every eventOur team watched the apps through every competition day, tuning as real usage arrived.

Technology

The right tools, not all the tools

Native Swift and Kotlin when performance and platform features demand it, React Native or Expo when one codebase makes commercial sense. The choice is made on evidence about your product and users, and we show you that evidence.
