Tail It is a free lifestyle application that provides the location of Tail It GPS trackers. The app uses GPS, WiFi, and LBS location tracking technology to give accurate position data at all times. It is equipped with smart and advanced algorithms for power saving and position location even when the app is not in use.

One of the app's unique features is that it enables you to have complete control over your visibility. You can hide your visibility from everyone or someone specific. Alternatively, you can choose to show your location only to friends or family, the group of people you know. The app allows you to track connected Tail It devices on your Map, which can be helpful in case of theft or loss of the device.
