The standards race to turn smartphones into sports accessories has heated up and it appears that ANT+, used by SRAM, Garmin, Adidas and others might win. As we mentioned in an earlier post, Polar has OEMed their technology to Nokia and developed a Bluetooth based Heart Rate Monitor to connect to a Nokia smartphone. Now a new Minnesota company, Pedal Brain, is offering an ANT+ accessory and application that will turn your iPhone or iPod into a full blown cycling computer.
