Snapchat is a social media platform that allows users to share moments through photos and videos. It has introduced features like 'Home Safe' and 'Arrival Notifications' to enhance location sharing and safety for its users. Snap Map, a feature within Snapchat, has over 400 million monthly active users and allows users to see friends' locations, discover local hotspots, and find things to do. The company aims to compete with services like Life360 and Apple's 'Find My' with these location-sharing features.
