Advanced GPS safety and tracking for road cyclists, mountain bikers, motorcyclists and horse riders. Fitting easily onto any cycle, motorbike or saddle, Ridersmate constantly tracks your location, speed, heading and altitude, then texts your loved ones should you become separated from your ride. At the same time, Ridersmate records data about your journey, which you can easily save, store and share with other Ridersmate users using this Ridersmate application for Mac OS X Mavericks/Yosemite. N.B. A Ridersmate GPS tracking device is required in order to effectively use this software (available seperately from the Ridersmate website).
