Till January of this year, the Wahoo Key for iPhone ($80) dongle pwned fitness on the iPhone. Why? Because the tiny, ubiquitous dongle gives the iPhone access to dozens of ANT+ sensors, and more fitness apps than any other system — turning your iPhone into a fitness-tracking powerhouse.
Then in January, Wahoo one-upped itself and introduced the Wahoo Blue Bluetooth heart-rate strap, which completely bypasses ANT+ and instead communicates via low-energy Bluetooth v4.0. Does this mean the Key is obsolete? Not by a long shot.
Wahoo’s popular ANT+ Fisica dongle, which allows the iPhone to read signals from fitness gadgets like heart-rate monitors, pedometers and bike sensors, is probably most widely used fitness iPhone accessory since its release a little over a year ago. And today, Wahoo took the first step toward killing it.
Presumably for those without an iPhone and its wealth of app-basedfitnessoptions, iHome has partnered with New Balance to offer a set of earphones packed with workout features, including a pedometer and a heart-rate monitor.
