This week Jawbone officially announced plans to launch a connected fitness device -- UP -- which the company has been working on for the past two years. As we reported earlier, the company's as-yet unreleased UP device will have plenty of competition from other dedicated or peripheral connected fitness devices.

By our count there are 10 other devices like UP either in the market today or coming to the market shortly. This list does not include the hundreds of smartphone apps that also help users track fitness metrics. Jawbone and the 10 companies highlighted here are betting that most people would rather not have to lug their smartphones around with them while they run -- or they're betting they are willing to carry both their phone and a companion fitness device.

Nike+ is one of the few offerings listed below that has a separate smartphone app as well as an option to use a peripheral device embedded in or clipped onto the user's running sneakers. One of the more innovative competitors, Valencell, offers technology that embeds the fitness tracking technology right into the user's headphones.

Read on for our list of 10 competitors to Jawbone's UP device and let us know if we missed any in the comments below.

Basis

Basis, which was previously known as PulseTracer, offers a wrist worn device called Basis Band that measures the wearer’s heart rate and other vital signs. Basis plans to allow third party developers to build apps that work with the device.

The startup secured $9 million in funding this past March and its team includes a former Google Health alum and a new CEO, Jef Holove, who was formerly CEO of Eye-Fi. While Basis Band is available for pre-order from the company’s website at $199, the company has yet to announce when the device will first ship.
