Geolocation technology plays a vital role in mobile apps by enabling them to determine a user's precise location using GPS, Wi-Fi, or cell tower signals. This functionality enhances user experience by providing personalized services such as navigation, local recommendations, and targeted advertisements. Geolocation allows businesses to offer tailored content relevant to a user's surroundings, improving engagement and satisfaction. Additionally, it is instrumental in location-based services like ride-sharing, food delivery, and social networking, thus becoming a significant aspect of the modern mobile ecosystem.
