In the wake of the "Spring Forward"
full reveal for Apple's watch, other fitness-oriented wearables have been struck from the inventory of both the Apple online store, as well as the retail lineup. Confirmed as removed are the Nike FuelBand, and the Jawbone UP. Some more specific health monitoring peripherals still exist, however.
Heart rate monitors such as the Tickr are still available, but for how long remains uncertain. Liz Dickinson, MIO CEO was reportedly told that the Fuse and other similar products would be removed from sale, and she recieved this notification "months ago."
Dickinson wasn't specifically told the Apple Watch was the impetus for the removal, but the inference is clear. She said of the removal that "they said they brought in a new executive in the marketing area who wanted to rework branding for the stores, and to make the Apple brand more front and center and clean up and minimize the number of accessories."
