Positioned as an alternative to the Apple-endorsed Nike + iPod Sport Kit, Wahoo Fitness’ Fisica Sensor Key for iPhone and iPod touch ($80) is a small, very expensive little Dock Connector dongle that allows certain biking, running, and fitness apps to receive data from ANT+ compatible fitness products including heart rate sensors, speed and cadence sensors, and weight scales. The company sells a Premium Speed and Cadence Bike Sensor ($50), Soft Heart Rate Belt ($60), and Stride Sensor ($80) as optional add-ons. Plugging in the Sensor Key leads to a collection of different free and paid apps, some capable of monitoring multiple sensors at the same time; Wahoo’s own app lets you see live data from the bike, stride, and heart rate sensors shown here.
