quite cheap to buy the full version, but quite usable in free/demo form :)
I had a look at both SportTracks and Ride with GPS.
Whilst both look good, they use the GPS speed data (which can give odd readings at times) rather than that from your speed sensor (if you have one).
From my research, I believe that an option to use the speed sensor data may be added in the future to Sporttracks, but it is by no means definite.
I've been using Sporttracks in its various versions for almost 3 years. Mostly I really like it, with two reservations:
Overall though, I highly recommend Sporttracks.
Strava? Is that new? Not heard of it....
Well it was new 6 years ago!!
Nice thread dredge :-)
