iSMARTtrain is a Mac OS X application for storing and reviewing your athletic training. It allows download of data from Polar Heart Rate Monitors. It is designed for use by multi-sport athletes, such as triathletes and duathletes, but can be used equally well by single-sport athletes, such as cyclists, runners, rowers or swimmers.

The software also allows you to review your training and race data as a graph, a table or as a monthly calendar. A Summary of the data can also be displayed, showing total distances, times, etc., per week or month. Equipment use can also be tracked as can user-defined values such as weight and energy burned.
