Mobile app development for businesses

We design and build mobile apps for Android and iOS for businesses in Poznań and across Poland. We specialise in React Native, which lets us create an app for both platforms from one codebase — faster and cheaper than two separate projects. When maximum performance matters, we also build native apps in Swift (iOS) and Kotlin (Android).

Every mobile app is built to order — from a workshop and UX/UI design, through development with regular demos, to publishing on the App Store and Google Play. We take care of push notifications, offline mode, integration with your API and data security. Mobile app development starts from €300, and you will get the exact cost after a free consultation.

Frequently asked questions

Find answers to the most common questions

Building a mobile app in React Native (one codebase for Android and iOS) starts from €300 for simple solutions. More complex apps with their own backend, push notifications and external integrations typically cost €750–€2 000. Native apps (Swift/Kotlin) start from €750. Every quote is preceded by a free consultation.
An Android-only app in React Native or Kotlin starts from €300–€375 for a simple solution. If you plan an iOS version in the future, it is worth choosing React Native from the start — an app for both platforms from one codebase is not much more expensive than separate projects.
A cross-platform app (React Native, Flutter) runs on Android and iOS from one codebase — lower cost and faster delivery. A native app (Swift for iOS, Kotlin for Android) gives maximum performance and full access to system APIs, e.g. advanced camera or sensor handling. We will help you choose the right approach after discussing requirements.
A simple mobile app takes 3–6 weeks of development. On top of that comes the App Store review process (Apple, 1–3 weeks) and Google Play (a few days). From project start to the app appearing in stores typically takes 2–3 months for a standard scope.
Yes — publishing in stores is included in every mobile app project. We help create developer accounts, prepare screenshots, description and metadata, and guide the app through the entire review process. If rejected by Apple or Google, we implement the required changes.
Maintaining a mobile app usually means the cost of backend hosting and developer accounts (Apple $99/year, Google Play a one-time $25) plus an optional support package. Minor updates and fixes can be handled within a monthly care package or billed hourly.
Yes — we operate from Poznań and serve clients across Poland. Meetings can be held in person in Poznań or online, and the whole process — from quote to post-launch support — can be done remotely.
