It can be used to track your speed, distance, and time on any type of road or path, such as a street, highway, trail, or mountain road. It is suitable for running, car driving, biking, or hiking.

The app displays your current, maximum, and average speed, as well as the direction, total distance, and time traveled. It is based on the GPS (Global Positioning System) sensor, which is present in most Android phones and tablets.
