Mobile App Development

Custom iOS and Android app development for companies across Brazil and Europe. Native and hybrid apps with React Native, focused on performance and user experience.

Mobile apps need to be fast, stable and pleasant to use — otherwise they get uninstalled in minutes. FDGE builds apps with React Native that deliver that experience on iOS and Android from a single codebase.

Why React Native

Most modern apps can (and should) be built with React Native: you keep one codebase, get near-native performance, faster time-to-market and lower maintenance costs. When the use case demands it (games, AR, specific hardware integrations), we drop into native Swift or Kotlin.

From idea to App Store

We handle the full cycle: planning and wireframes, interface design, development, backend integration, testing, store submission and ongoing maintenance. You follow each delivery with testable builds in staging.

Push, offline, integrations

Apps shipped by FDGE are ready for the real world: push notifications set up, analytics to understand usage, offline mode when needed, deep linking and integrations with APIs, payments and social authentication.

Who we work with

Companies looking to digitise customer service, build loyalty with rewards programmes, sell in-app, or create mobile communities. We also work with startups validating an MVP app quickly.

Frequently asked questions

Do I need two separate apps for iOS and Android?

No. We work with React Native, which lets us maintain a single codebase running on iOS and Android with excellent performance. This drastically reduces development and maintenance cost.

Do you handle store submission?

Yes. We manage the full submission process to the Apple App Store and Google Play, including developer accounts, screenshots, descriptions and review communication.

Can the app work offline?

Yes. When the use case requires it, we implement an offline-first architecture with automatic sync once the device is back online.

How much does building an app cost?

Simple apps start at around €6,000 / R$ 30,000. Apps with backend, authentication, payments and complex features can range from €16,000 to €50,000+ depending on scope.
