Apple removes Nike FuelBand and Jawbone UP from its stores as Apple Watch launch looms
Other fitness monitors are still listed for sale in the online Apple Store, although they are not worn on the wrist. For example, both Wahoo and Polar have monitors that are worn around the body. The Jawbone UP Move clip-on finess tracker is also still available online.
Apple had already stopped selling popular fitness bands made by Fitbit last year after the wearable manufacturer decided not to allow its products to integrate with Apple's HealthKit. The latter keeps track of the fitness and health data generated by third party fitness trackers, and the Apple Watch once it is released.
Nike, for its part, has been focusing on software instead of hardware and its health and fitness focused Nike+ app will be available for the Apple Watch.
