The Good The Jawbone Up is comfortable, durable, and effortless to wear. Its mobile app is intuitive and presents data well.

The Bad The Jawbone Up lacks a screen. It only syncs with iPhones and some Android devices, so there's no other way to view your fitness data. It connects via a less convenient wired connection.

The Bottom Line The new Jawbone Up is comfortable and durable, but limited support means this gadget won't make sense for many phone users.

Editors' note, May 9, 2013: This review has been updated to reflect the addition of Android support.

Many high-tech fitness products have hit the market recently, all aiming to be better ways to help you get in shape. The newly redesigned $129.99 Jawbone Up, however, stands out by pushing the personal activity tracker into new territory. Unlike traditional pedometer-style devices, such as the Nike FuelBand and Fitbit One, the Up is designed to be worn 24 hours a day, 7 days a week, all to paint a detailed picture of your health and prod you to move more. While the Up band is small, durable, and comfortable enough to wear on your wrist around the clock, the gadget has big drawbacks. For instance, it lacks a screen, Bluetooth, or even a way to check your status other than via its iPhone and Android apps. That said, after a bumpy initial launch last year, the revamped Jawbone Up is indeed an innovative, though not perfect, personal fitness tool.

Much of the Jawbone Up's appeal lies in its groundbreaking design. The Up is essentially a complex bundle of electronics, a battery, a motion sensor, and flexible circuit boards, all stuffed into a twistable rubber skin.

To save space and cut down on weight, Jawbone kept controls and indicators on the Up to a bare minimum. The circular bracelet-shaped device has just one silver square button on one end. The Up band's opposite side is tipped with a nylon cap that covers its 3.5mm headphone plug. You use the plug to both sync data with your phone and charge the Up's battery via an included USB adapter.

Right below the button sit two status lights, one drawn in the shape of a starburst and the other a half moon. These lights steadily glow or blink green or red, depending on which mode the Up is in or which function it's performing. If you're looking for a gadget with fancy OLED eye candy such as the Nike FuelBand or Fitbit One, you'll be disappointed. Since the device lacks a true alphanumerical display, the Up also can't function as a high-tech watch like the Motorola MotoActv can.

At 0.8 ounce, though, the Jawbone Up is very light, especially compared with other wrist-style fitness products (the FuelBand is 0.95 to 1.13 ounces, depending on how many spacers are used; the MotoActv is 1.2 ounces). In fact, I found the Up band very comfortable to wear, to the point where I forgot it was on my wrist entirely.

According to Jawbone, that's the entire point of the Up: to be a device that effortlessly integrates into your daily life. To make it even more likely the Up will stay strapped to you, Jawbone also designed the Up to be water-resistant; you can even shower with it on. Just don't take the Up band swimming, since it can't handle being submerged in liquid.

For a mobile device that lacks a screen and has just one button, the Jawbone Up certainly does quite a bit. At its core, the Up band is a fancy pedometer that measures your movements and overall activity level by the steps you take. It also can calculate the number of calories burned (based on your age, height, and gender), plus it breaks down your daily activity in terms of total active time, longest time you were most active, and, my favorite, longest time idle.

All this data is displayed through your iPhone or Android handset using the Up's companion app. I'm glad that Jawbone made good on its promise to offer support for Android, but be advised that only some devices are officially supported. Check here for the full list.

The Up band goes well beyond the capabilities of a typical pedometer. The device tracks your sleep and reports the quality of your snoozing by time slept and deep versus light sleep, plus the total time you spent in bed. You can also see how long it took you to fall asleep and how many times you woke up during the night.

This is all well and good, but what do you do with this data once you have it? The real power of the Jawbone Up system lies not merely in logging personal stats but in the fact that you can use it to set goals you strive to accomplish. For instance, the default number of daily steps the Up recommends you take is 10,000. You can increase that all the way to 18,000, though, if you choose.

Similarly, the Up application recommends you get 8 hours of sleep each night, though you can raise this to a slothlike 10 hours within the Sleep Goal section of the app. Your progress toward your sleep and activity goals is displayed on the app's home screen. They're represented by two easily discernible color-coded bars (blue for sleep, orange for steps), which also show raw performance numbers and their percentage value in relation to your current goal.

For further motivation, below your performance stats the Up app provides daily inspirational factoids with health advice trivia. For example I was mortified to learn that lack of sleep increases cravings for high-calorie/high-fat foods. Yikes!

Additionally, clicking on a smiley face (what Jawbone calls the mood icon) lets you tell the Up system how you're currently feeling. Moods range from Totally Done on the low end to Amazing as the ultimate high. Of course, the app allows you to describe your mood in your own words, too. Jawbone claims that the Up notes how you feel and maps this against actual performance data to provide more personal insights over time.

Another interesting aspect of the Up application is its social component. The software lets you search for friends with Up accounts and then invite them to become a member of your team. Once linked, team member performance is listed in a real-time social feed on the home screen.
