IpBike is free but has a 1,000,000 wheel revolution limit (or equiverlent if no real wheel sensor is present).  This is ample to trial the application.  The limit has nothing clever enforcing it so if yopu realy want to avoid getting IpBikeKey which unlocks the limit then just uninstall it and reinstall it and you have another 1,0000,000 wheel revs.

IpAntMan is free.

IpBikeKey is a sold app that unlocks the 1,000,000 wheel revolution limit on IpBikeIpBike.
