Sports and fitness app makers Pear Sports are now offering a free app that interfaces with a $150 kit sold at Apple retail stores to help users achieve fitness or weight-loss goals using personalized coaching from top personal coaches based on the biofeedback the kit sends the app. The product includes a Bluetooth heart monitor, a pair of Pear earbuds for listening to music and the coaching, and the app for iPhone or iPod Touch. The app provides real-time feedback and encouragement using data gained from the heart rate monitor.
