Smart technology meets our most popular display, the padrone. Download the free Cat Eye cycling App, stash your smart phone away safely in your jersey pocket or saddlebag and hit the road. Use mirror Mode to get gps-powered ride data, sms (text), call and email alerts from your phone displayed on the padrone smart's screen while your phone is kept safe from the elements in sleep Mode, preserving the battery. When carrying a phone isn't ideal, use sensor Direct Mode to get speed, cadence, heart rate and power data directly from Bluetooth smart wireless sensors. After use in either Mode, seamlessly upload ride data to Cat Eye Atlas, starve and training peaks. Please check Cateye.Com to see if your smart phone is compatible.
