Very complete
Cyclometer tracks a lot of stuff. Speed, cadence, power, elevation gain and even temperature. It tracks laps and you can import routes and competitors. If you want to share your rides Cyclemeter can upload them to Strava or you can download the files and upload in whatever tracker you use.
Have I mentioned that the complete version is cheap? Because it is.
