Any iOS app for measuring distance between 2 points ?

Hi, we are a FTTH deployment company and we need to measure the raw distance of the path we go for point A to point B and save them for future reference.

For example, we are a point A, we save Point A and then start on a bike.
And reach point B and save the trip, then it should show me how much distance I covered and which path I took and I should be able to save that exact path trip with all details like longtitude and latitude of point a and b and the distance in km or meter.

So, is there any such app ?

I just paid for one app called Waypoint, but its buggy and doesnt work
