Mobile apps for iOS and Android
From the first sketch to the App Store and Google Play: we design, build and launch apps that people keep on their home screen, and we stay around after launch.
We've built mobile apps since 2008, the year the App Store opened. Since then we've shipped festival apps that have to hold up when the whole crowd opens them at once, apps for global brands, smart-home control for a US company and apps for startups finding their first users.
Most new apps we build use Flutter: one codebase for iPhone and Android, with native performance. When a project needs native Swift or Kotlin, we write it natively. Either way you get one small team responsible for the whole app: design, code, back-end, store releases and support.

What we deliver
- Discovery & scopeWe turn your idea into a clear plan: users, features, priorities and a realistic first version.
- UX/UI designFlows, wireframes and clickable prototypes you can test before we write code.
- iOS & Android appsFlutter for one codebase on both platforms, or native Swift and Kotlin when it's the better fit.
- Back-end & admin panelAccounts, content, payments and the dashboard your team runs the app from.
- Payments & subscriptionsIn-app purchases, subscriptions and card payments, done the way Apple and Google require.
- Notifications & analyticsPush notifications, crash reporting and the analytics you need to improve the app.
- Store launchApp Store and Google Play listings, reviews, test releases and the launch itself.
- Support after launchUpdates for new iOS and Android versions, fixes and new features in regular releases.

How much does an app cost?
It depends on what the app needs to do: the number of screens and features, whether it needs a back-end, payments or integrations, and how polished the design should be. After a short discovery call we send a clear estimate for a first version. Starting with a focused first version and growing it from real use is usually the best value.
How long does it take to build an app?
A focused first version can launch within weeks; larger platforms with back-ends and integrations take a few months. After discovery you get a timeline with milestones and working builds along the way, so you're never waiting in the dark.
Flutter or native: which should I choose?
For most apps, Flutter is the best value: one codebase for iPhone and Android, with native performance and one team to pay. Native Swift or Kotlin is better when an app leans heavily on the newest platform features or deep hardware access. We've done both since 2008 and recommend what fits your project.
