@gschenk Yes. If you have a fancy phone then there's no cost. Its worth using for a week or so, one ride isn't enough to give you any results to compare.
I like using it for a year-goal, like total elevation or distance.
Plus it helps keep track of mileage accrued on parts, provided you enter them at change time.
Anyway I like Strava. It's pretty decent for analyzing the ride. It gives me the distance, average speed, instant speed and it also puts them on a map.
Speaking of data, you can also download it. I think it's in GPX format.
