App-Entwicklung: React Native New Development

React NativeNew Development

Building a new app from scratch in React Native means making the right decisions from the start: architecture, navigation, state management, and testability are not retrofitted but built solidly from day one. We develop React Native apps that feel native, are maintainable, and scale with your product.

Challenges you'll recognise

  • Your React Native project has, after a few months, an architecture that no one fully understands anymore.
  • You are starting an app project and know that the first architecture decisions will determine years of maintainability – and want to get it right this time.
  • You need an iOS and Android app in market quickly without sacrificing the quality that enables long-term development.

Architecture Design

Decisions made in the first weeks of a project determine maintainability for years. We define navigation structure, state management strategy, API layer, and folder conventions before the first feature development begins. A documented architecture prevents the project from becoming a black box after six months.

Navigation and State

React Navigation for routing logic combined with a clear state management approach forms the backbone of every React Native app. We choose the state solution based on your app's complexity – from simple Context to Zustand or Redux – and keep the solution as simple as possible.

Testing Strategy

We build testability into the architecture rather than treating it as an afterthought. Unit tests for business logic, integration tests for critical flows, and snapshot tests for key UI components ensure that further development does not produce unwanted regressions.

Store Preparation

From app icons and splash screens through review guidelines to store listing assets – we guide the entire process through to a successful publication in the App Store and Google Play. The accounts run under your name so you retain full control at all times.

Good to know

Architecture Before Features

We define navigation structure, state management, and API layer before feature development begins. This prevents architecture drift and keeps the project maintainable for future teams.

TypeScript from Day 1

Static typing makes code more readable, catches errors early, and significantly eases onboarding of new developers. We start every project with consistent TypeScript.

You Stay in Control

Code on your repositories, App Store accounts in your name, full architecture documentation. You are never locked in to us for ongoing operations.

Frequently asked questions

How long does a React Native new development take?
A simple app with few screens can be ready in a matter of weeks. A complex app with many features, backend integration, and store release typically takes several months. We estimate effort realistically after a requirements analysis.
What do I need to get the project started?
Ideally a clear picture of core functions, target audience, and target platforms. A complete specification document is not required – we help structure requirements and set priorities. The clearer the requirements, the more accurate the effort estimate.
Do I remain the owner of the code?
Yes. We develop on your repositories and with your App Store accounts. The code belongs to you – you are never dependent on us as a service provider to continue developing your app.
