OTAG Technologies has announced the release of iSMARTtrain 2.0.3, the latest update to the company’s Mac OS X application for downloading from Polar heart rate monitors and tracking and analyzing sports training. The latest release contains many bug-fixes and includes support for the Polar S725x Heart Rate Monitor. The software is designed to allow multi-sport and single sport endurance athletes, for example triathletes, duathletes, runners and cyclists, to download training data, such as heart rate, cadence, speed and power, from Polar heart rate monitors and analyze it in graph, table and list formats. Information about training sessions, for example duration, distance and speed can also be similarly reviewed. iSMARTtrain is priced at US$40.
