The Wahoo TICKR is a heart rate sensor with both ANT+ and Bluetooth Smart. Thanks to this, you can use the TICKR with ANT+ products, like sports watches and cyclocomputers, but also pair it with a smartphone with Bluetooth 4.0 (Smart). The sensor also keeps track of how many calories you burn and what distance you've run. Look at your data in popular apps like Runkeeper and MapMyRun. Get the most out of your TICKR with the Wahoo Fitness app. Here, you can choose different heart rate programs to lose weight or improve your endurance.
