Why It Matters
Building a mobile app traditionally means hiring one team for iOS (using Swift) and another for Android (using Kotlin), then keeping both versions in sync as features are added. React Native reduces that to a single team and a single codebase that produces both versions. For businesses, this means lower development costs, faster time to market, and simpler maintenance. It also allows companies that already have web developers with React experience to move into mobile development without hiring entirely new skillsets. The trade-off is that highly platform-specific features or performance-critical applications (like 3D games) may still benefit from fully native development, but for the vast majority of business applications (dashboards, tools, e-commerce apps, communication platforms), React Native delivers native quality at a fraction of the cost.
Example
A field services company needs a mobile app for its engineers to receive job assignments, capture photos of completed work, collect customer signatures, and submit reports. Rather than building and maintaining separate iOS and Android apps, the company builds a single React Native application. Engineers on iPhones and Android devices get the same functionality with a native feel on each platform. When the company adds live GPS tracking for dispatchers, the feature is built once and deployed to both app stores simultaneously. More definitions are in the glossary.
