iSMARTtrain V4.1 Released
Finally, we’ve released iSMARTtrain V4.1. This new version includes several new analysis graphs, improved swim tracking and many bug fixes.
Power-Duration Graph
Power-Duration Graph shows the maximum average power for each duration from one second up the duration of the session.

Force-RPM Graph
Force-RPM Graph is based on a concept by Dr Andrew Coggan and shows the force on the pedals and rotation speed of the cranks for each data point recorded. The graph has four quadrants:
- The top right is high cadence and high force. Sprint efforts are in this area.
- The top left is low cadence and high force. Accelerations from stopped in a big gear are in here.
- The bottom left is low cadence and low force. Recovery rides and easy spinning are mainly in this area.
- The bottom right is high cadence and low force. A time-trial effort generally be this area.
