Overland GPS Tracker is an iPhone application developed by Aaron Parecki. This free utility tool tracks your location and securely sends data to a server of your choice. The app is designed to save data while offline, ensuring no information is lost, and then transmits it in batches to the server.

With Overland GPS Tracker, users have access to highly customizable tracking settings, allowing for optimal control over their tracking preferences. Whether you prefer detailed track logs at the expense of battery life or tracking only significant movements to conserve energy, this app caters to your needs.

The program supports tracking various activities such as bike rides, runs, walks, car trips, and train journeys. It's important to note that prolonged use of GPS in the background may lead to a significant decrease in battery life.
