What a mobile app developer does

A mobile app developer builds and maintains the apps people use on their phones and tablets, either natively for iOS and Android or across both from one codebase.

‍

On a delivery team, a mobile app developer typically:

  • builds iOS apps in Swift or Android apps in Kotlin, or both platforms at once with Flutter
  • connects the app to your APIs and back end, including sign-in, payments and notifications
  • tests on real devices and screen sizes, and fixes what breaks
  • prepares releases for the App Store and Google Play, and handles the review process
  • keeps apps working through each year’s iOS and Android updates

‍

Native development gets the most from each platform. Cross-platform development with Flutter or React Native ships to both from one codebase. If your team works in React Native, see our React Native developers.

When to bring in mobile app developers

Mobile app developers make the difference when an app is part of the work and your team is built for the web.

You’ve won a project with an app in it
Your team is strong on web, and the client wants iOS and Android too.
You’re adding an app to your web product
Customers are asking for one, and nobody on the team has shipped to the App Store.
You need to choose between native and cross-platform
Getting it wrong is expensive, so you want people who’ve built both.
This year’s iOS or Android update broke something
Every major release needs work, and it lands when your team is busy.
App store ratings are slipping
Crash reports and bug fixes are piling up faster than your team can clear them.

Mobile app developer profiles

Mobile work varies with the platform and the product. These are some of the profiles we supply:

‍

  • iOS developer. Builds native iPhone and iPad apps in Swift and SwiftUI.
  • Android developer. Builds native Android apps in Kotlin and Jetpack Compose.
  • Flutter developer. Builds one app for iOS and Android from a single Flutter codebase.
  • Mobile lead. Sets mobile architecture and release processes, reviews code and leads a small group of developers.

‍

React Native developers have their own page. If you need a different mix, tell us what the work involves and we’ll match profiles to it.

How teams use mobile app developers

One mobile developer or a whole app team, for as long as the work runs. You can start part-time, for example three days a week moving to five, and scale down with two weeks notice.

Where our mobile app developers work from

Most work nearshore in Central and Eastern Europe on UK hours, so they’re online when your team is. Where a client needs people on site, developers can work onshore in the UK. For US work, developers in LATAM work US hours.

FAQs
Mobile app developers
How much does it cost to hire a mobile app developer through Brightbox?

Mobile app developers are on daily or hourly rates, which depend on seniority, platform and where they work from. Ask and we’ll send a rate card, usually within hours.

Can you build an app for us?

Not as a project we run on our own. We supply mobile developers who join your team and work under your direction, so you keep control of the build, the code and the roadmap. If you have someone to lead the work, such as a CTO, product owner or technical partner, we can supply the developers to build it with them, from a single iOS or Android developer to a whole app team. If you need someone to own the entire build from start to finish, we can introduce a proven delivery partner from our network who takes on that responsibility.

Native or cross-platform: which do I need?

Native apps, built in Swift for iOS and Kotlin for Android, get the most from each platform. Cross-platform apps, built with Flutter or React Native, ship to both platforms from one codebase, which often suits a smaller team or budget. Tell us about your app and we’ll suggest the right profiles.

Do your developers work with Swift, Kotlin and Flutter?

Yes. Tell us your platforms and tools and we’ll match developers with experience in them, including Swift, SwiftUI, Kotlin, Jetpack Compose and Flutter.

Do I need a React Native developer?

If your app is built in React Native, or you’re planning one, yes. React Native developers have their own page.

Can they publish to the App Store and Google Play?

Yes. They prepare releases and work through the review process with your team, using your developer accounts.

Can they work on our existing app?

Yes. They join your team and work in your repositories, tools and release processes.

How quickly can a mobile app developer start?

Usually within days, rather than the months a permanent hire takes.

Can a mobile app developer work remotely?

Yes. Most work remotely, nearshore in Central and Eastern Europe on UK hours, so they’re online when your team is. Where a client needs people on site, developers can work onshore.

Can we hire mobile app developers for just a few months?

Yes. There’s no minimum term, and you can scale down with two weeks notice. Engagements shorter than about six weeks rarely work, because onboarding takes too much of the time.

Who owns the code?

You do. Everything they build is yours.

How do you handle IR35?

We’ve worked both inside and outside IR35, and we work with a partner to help with status determinations when needed.

Need mobile app developers for your next build?

Send us a short brief. We’ll come back with profiles and rates, usually within a day.
