Mobile app development.
iOS and Android apps, from idea and design to App Store and Google Play.
We develop apps in Flutter and React Native: one codebase for both platforms means faster development and lower cost, with native performance. When a project demands it, we go fully native. We cover the whole cycle: UX/UI design, development, backend, publishing and growth. One team, one responsibility.

Complete App Store and Google Play process under your ownership.
Data security
Encryption, secure authentication and privacy best practices.
Maintenance
New versions, new features, ongoing support.
Two platforms, one budget.
Development cost for iOS + Android
Flutter and React Native share one codebase across platforms.
-40%
lower development cost, and one team for every future change.
Industry estimate for typical business apps.
Mobile app security
A phone is personal. Trust must not be broken:
- Encrypted traffic: every server call over TLS.
- Biometric sign-in: Face ID / fingerprint instead of passwords.
- Secure token storage: Keychain and Keystore, not plain files.
- Store review ready: Apple and Google standards from v1.
- GDPR privacy: only the permissions we truly need.
What drives the price of a mobile app
The biggest factor is not the number of screens, it is how much logic sits behind them. An app that displays content and sends notifications is one level of work; an app with user accounts, payments, maps and real-time sync is another entirely. That is why, before any estimate, we sketch out what the app actually does, screen by screen, and only then talk numbers.
The second factor is the backend. If the app has accounts, content that changes or communication between users, it needs a server side: a database, an API and an admin panel. We build both halves, so you get one team and one line of responsibility instead of juggling vendors. And because we work in Flutter and React Native, a single codebase covers both iOS and Android, which in practice means a 30 to 40% lower price than two separate native builds.
The app types we build most often: ordering and booking apps, internal apps for field teams (delivery, servicing, stocktaking), apps that accompany an online store, and MVP versions for startups testing an idea before the big investment. Your idea does not have to be fully formed. Tell us about it and we will help shape it.
How much a mobile app costs
An MVP app, the smallest useful product for validating an idea, starts at €4,500. Apps with accounts, payments and an admin panel start at €8,000, and complex platforms are quoted per project. The detailed breakdown is in our guide to mobile app development cost, with ranges also on the pricing page. We work in Flutter and React Native: one codebase for iOS and Android, which practically halves the cost compared with two separate builds.
A real example
The Termin app, salon appointment booking with search, a calendar of free slots and reminders, shows our approach: simple for the user, practical for the business, with a backend and a staff panel behind it. We run the whole process, from idea to publishing on the App Store and Google Play.
Mobile app FAQ.
How much does a mobile app cost?
It depends on screens, features and integrations. Cross-platform development (Flutter/React Native) typically costs 30–40% less than two native apps. Free estimate for your idea.
Does one app work on both iPhone and Android?
Yes. We use Flutter and React Native: one codebase, both platforms, native performance and look.
Do you publish to the App Store and Google Play?
Yes. We handle the entire publishing process under your accounts. The app remains fully yours.
