Tracker 8 is a free iPhone app developed by Vijay Sachan in the Travel & Navigation category. With this app, users can easily view and share the real-time location of their family and friends.

In addition to tracking others, Tracker 8 also allows users to track their own routes, paths, runs, and walks. Users can save their current or favorite locations for easy access later on. The app also supports the import and export of GPX and KML files, making it convenient for users to share their routes with others.

One of the standout features of Tracker 8 is its ability to show live movement, time, and distance. Users have the option to share their location in real-time or at predefined intervals of 5, 15, or 30 minutes. Despite the continuous use of GPS, the app has been designed to have minimal impact on battery life, consuming only 5-8% in 24 hours when sharing locations at the predefined intervals.

Tracker 8 also provides notification alerts when the location of family and friends changes, ensuring users are always aware of their loved ones' movements. The app keeps a history of tracked locations, allowing users to easily access past data by date, month, and year. Additionally, users can view a street view of any saved location for a more immersive experience.

Please note that continued use of GPS running in the background can significantly decrease battery life, so users should be mindful of this when using the app.

Overall, Tracker 8 is a versatile and user-friendly app that offers a range of features for tracking and sharing locations. Its efficient battery usage and notification alerts make it a reliable choice for keeping tabs on loved ones' whereabouts.
