I use this app to count distance of daily running, its quite useful to track distance you have covered while running- just start gps+ data connectivity and start running task.
Pros:
Can be used to track distance travelled while walking or running.
It also gives information on calories burnt during said activity. This is most important if you are health concious and trying to gain/loose weight.
Cons:
It displays steps you took even though you are travelling by vehicle at slow speed . Steps information seems to be inaccurate considering most of the people tends to keep gps off.
No way to export the data , which could be useful in other apps or sharing purpose.
