Distance Tracker | GPS Distance Measure Tool
You can track distance in meters as straight line (from point A to point B) which is distance you can measure on the map with the ruler or you can track travelled distance which is the real distance you have travelled.
There is also reset button that resets your start location to the current location and right now all distance is measured in meters.
Distance tracker is also ad free and I will never add any ads in the future versions. My plan is to add only additional extra features.
