A native React Native library for geofencing and region monitoring on iOS and Android.
react-native-boundary is a React Native library that enables geofencing and region monitoring in mobile applications. It allows developers to define geographical boundaries (geofences) and trigger events when users enter or exit those areas, solving the need for location-aware functionality in cross-platform apps.
React Native developers building location-based applications such as proximity alerts, location-triggered notifications, or geofenced content delivery.
Developers choose react-native-boundary because it provides a simple, unified API for native geofencing on both iOS and Android, ensuring better performance and battery efficiency compared to JavaScript-only solutions while maintaining cross-platform compatibility.

Uses iOS and Android native geofencing APIs for optimal battery efficiency and performance, as highlighted in the README's key features.
Offers a consistent JavaScript API for both iOS and Android, simplifying development without platform-specific code.
Supports event callbacks in both foreground and background, enabling location-triggered actions even when the app is inactive.
Provides straightforward functions like add, remove, and removeAll for easy handling of geographical boundaries with unique IDs, as demonstrated in the usage example.
Limited to ENTER and EXIT events only, lacking advanced geofencing capabilities such as dwell time monitoring or dynamic radius adjustments.
Requires manual linking steps for iOS and Android, which can be complex and error-prone, especially for developers unfamiliar with native integration.
The README suggests a radius greater than 50 meters for reliability, indicating potential issues with accuracy or performance for small geofences.
