Jawbone is a wearable device company that has been in business since 2000.  The company is truly focused on helping guide people to a healthier life. "Get UP and find the better version of you" is their motto and all of their devices have been designed with this in mind.  They provide personalized insight for users and are a world leader in consumer technology.  Jawbone's approach to fitness tracking is unique, with over 600 patents related to its technology and processes. 

• Great features
• Food tracking
• Device options

First, Jawbone's UP system is truly impressive. It features an open API, which allows it to seamlessly integrate with other fitness and weight loss apps, including the popular RunKeeper, MyFitnessPal, Strava and Lose It! apps. Offering so many integration options means that you can easily get a full, detailed picture of your health, as well as have the option to tailor the tracking to your specific needs rather than work within the confines of only one app. This also saves time, as you'll only need to check one app to see your status instead of three or four. UP is also well-designed from an aesthetic standpoint: it's easy to read and navigate, and houses details in themed groups so you don't have to click through multiple screens.

Second, if tracking food is a priority for you, the UP is a wise choice. You can log how much water you drink and what you eat, including selecting from lists of popular restaurant menus, to keep track of your calorie and nutrition intake. And UP's Healthy Food Score feature will make it easy to see if you're on track.

Third, Jawbone offers 4 different devices, depending on what you as a user want.  The UP Move is a baseline tracker for people wanting to focus on health and weight loss.  The UP4 has detailed activity and sleep tracking with AMEX payment built in, for those wanting to be thoroughly involved in their fitness.  The UP Move is only $49.99 and the Up4 is $199.99, with the UP2 and 3 in between.

• No lights or display screen
• No alerts

The biggest drawback of the UP System is that there are no lights or display screen - you'll have to check the app if you want to monitor your progress throughout the day. You also won't receive any reminder alerts with the cheaper model, so you'll need to keep yourself motivated and moving by remembering to check the app or harnessing your competitive spirit.

Jawbone is truly an innovative leader with its software platform, but it could improve upon its device design by adding sync options to the cheaper model. A display screen would be a nice option as well, however, the software is so appealing that you'll probably be tempted to check it several times a day anyway - so you may not even notice that you don't have a display screen.
