Maps and Location
Showing where the user is without burning their battery.
react-native-maps gives you Apple Maps on iOS and Google Maps on Android with one component. expo-location gives you the device's coordinates. The watch-out is foreground vs background location — background needs a separate permission, separate plist entry, and a real reason. Don't ask for what you don't need.
