Swim+ represents a giant leap forward in technology that provides real time personalized coaching using an advanced artificial intelligence system that adapts to daily changes in your health & fitness to help maximize your training & performance. Swim+ alerts you to critical data: laps & sets during your swim, drifting out of the target speed, heart rate, stroke cadence, or effort for your workout, new best times or efforts, and acute or chronic fatigue limits indicating that you should stop to minimize the risk of injury.
