Our services

Mobile app development

iOS and Android apps that people enjoy using – designed, built and launched by one team.

Let’s talk about your project What we build

We build mobile apps with React Native: one codebase for iOS and Android, native look and feel, and faster delivery than two separate native teams. Where a project needs it, we also build fully native.

From healthcare and pregnancy apps to sports, gaming and business tools, we have shipped apps used by thousands of people across Europe.

A few useful answers

Mobile app development

How much does it cost to build an app?

It depends on features and integrations. An MVP typically starts in the lower five figures; complex apps with custom backends can reach €100,000 or more.

How long does app development take?

A focused MVP usually takes 2–3 months, a complex app with backend around 3–4 months.

Native or cross-platform?

For most business apps React Native is the best balance of cost, speed and quality. We recommend native only when the app needs deep device features.
