Back-Track is a free iPhone app developed by Pilot X Ltd in the Travel & Navigation category. This app utilizes the GPS feature of your device to help guide you back to any location you've marked. With Back-Track, you can easily save your current position by marking the location, ensuring that you can find your way back whenever needed.

One of the key features of Back-Track is the ability to create and edit unlimited preset destinations. This allows you to save multiple locations such as where you parked your car or the hotel you're staying at. Additionally, you can manually enter longitude and latitude coordinates if necessary.

The app offers a variety of user interface styles to choose from, allowing you to customize your experience. The Heads-Up Display (HUD) provides detailed information about your current and target locations, ensuring you stay on track. The settings panel gives you full control over the information displayed and the measurement units used.

It's important to note that continued use of GPS running in the background can significantly decrease battery life. However, Back-Track includes a power saving mode to help conserve battery life when needed.

Please remember that the accuracy of Back-Track is dependent on the accuracy of your device's GPS. For optimal results, it is recommended to keep your device away from magnets and electronics, and calibrate it if prompted to do so.

With its user-friendly interface and convenient features, Back-Track is a reliable companion for navigating back to marked locations.
