The Good The Basis B1 Band by Basis Science tracks steps, calories, heart rate, and sleep automatically, syncs wirelessly via Bluetooth with iOS devices and a variety of Android smartphones, and has clever motivational software. Its watch design is handy and comfortable, too.

The Bad The Basis Band is big, bulky, and expensive compared with other health trackers.

The Bottom Line The $199 Basis Band offers a powerful mix of sensors and motivational tools, but pass if you'd rather spend less on a fitness tracker or aren't partial to big, watch-style designs.

Editors' Top Picks

The $199 Basis B1 Band from Basis Science puts a new spin on the personal health monitor. It may be larger and more expensive than similar products, but it's also way more capable, plus its watch-style design is very handy, and it syncs with iPhones and various Android handsets wirelessly.

Like many similar products on the market, such as the Jawbone Up, Nike FuelBand, and Fitbit Flex, this watch-style gadget tracks steps and basic activity level. Additionally, the Basis Band measures how long and how well you sleep, a trick both the Jawbone Up24 and Fitbit Force manage as well. What really sets the Basis Band apart is that it also keeps an eye on heart rate, skin temperature, and perspiration. It uses this information to record sleep data and is the first device of its kind to do so automatically. Also innovative is how the Basis Band pushes users to adopt "healthy habits" such as burning more calories by taking walks throughout the day. All this makes the Basis is one of the best personal fitness trackers available.

Editors' Note, January 27, 2014: This review was updated to include our experience using the Basis Band's enhanced sleep and activity tracking.

Design
When I first got my hands on the Basis Band, I admit I wasn't blown away by its styling. At first glance the Basis looks like a standard, even basic digital watch. It's not exactly thin, either; its monochrome LCD screen is small, and there's only one obvious button, which is located on the right edge.

Flip the watch over, however, and you'll begin to realize that this is no ordinary timepiece. On the bottom of the device are six stud-shaped sensors and two green LED lights. The Basis uses these to measure your heart rate by estimating blood flow through your skin.

Additionally, the four silver circles in each corner of the watch face (which I initially thought were ordinary screws) are capacitive buttons. The two buttons on the right cycle up and down through views of steps, calories, and heart rate data. The key in the top-left corner activates the Basis Band's backlight, and tapping the bottom-left button pulls up the date.

It turns out that these fancy touch-sensitive controls aren't just for show. They help you operate the watch in wet environs without fear of moisture entering the Basis' chassis. Indeed, the Basis Band is splash-resistant, so taking it out in the rain or keeping it on in the shower isn't a problem.

On the left edge of the watch are four metal contacts. They connect to the Basis Band's wired charging cradle, which in turn plugs into USB ports. The folks at Basis Science claim the watch's lithium polymer battery can run the Band for four days straight between charges.

The original Basis B1 Band model shipped with a stock plastic strap (black or white). To add a bit more oomph to the Basis Band's visual impact, Basis Science also offers artist-designed wrist straps to replace this rather plain band. For example the company once sold upgrades such as the Cityscape band ($34.95) which starts with a white background but is stenciled with a stylized cartoon street scene.

Sadly this Cityscape option appears to have sold out but other choices include the colorful Kaleidoscope ($34.95) and Electric Spring ($34.95) straps. My favorite though is a more conservative and more expensive Carbon Steel ($49.95). It gives the Basis Band a handsome touch of metallic silver and black silicone.

You’ll be glad to learn, however, that in January 2014 Basis began bundling the premium Carbon Steel strap with its tracker. Called the Basis Carbon Steel Edition, the fresh package costs the same $199 that the original Basis B1 band did, while its predecessor drops to $179 and will be sold until supplies are exhausted.

Features
As mentioned before, the Basis Band uses a built-in accelerometer to record the steps you take. But its features go way beyond those of the average pedometer. The device relies on a pair of green LED emitters to pulse light into your wrist periodically. An optical sensor uses the pulse to calculate the amount of blood flowing through your skin, and ultimately your heart rate.

Other sensors take note of your skin temperature and perspiration level. Since body temperature typically drops significantly during sleep, as does heart rate, the Basis uses the data its sensors generates to determine the length and quality of your slumbering. What's more, the device does so automatically. Other gadgets, such as the Jawbone Up24 and Fitbit Force, require that you press a button to begin sleep logging. After a very long day, remembering this step can be a tall order.

Deeper sleep analysis
Automatically capturing a snapshot of how long you sleep is just the beginning of the Basis Band’s nocturnal abilities. Indeed, thanks to a recent software update the gadget will now breakdown recorded sleep by several criteria.

These include the percentage of time the band thinks your mind spent restoring itself in REM (Rapid Eye Movement) sleep, deep sleep (recharging the body), along with how many times you tossed and turned, or how often your Zs were flat-out interrupted. With all this measured, the Basis mobile app (Android and iOS) will also provide a personalized sleep score. Listed as a percentage, Basis says this stat is calculated by comparing nightly slumber against your current lifetime sleep performance.

Automagical fitness tracking
Sleep isn’t the only bodily activity the Basis Band tracks and quantifies on autopilot. The device also leans heavily on its array of advanced sensors to figure out just what kind of physical exertion you're currently engaged in. Termed Body IQ, the watch can comprehend when you’ve started out on a serious stroll, begun to actually run, or even have hopped on a bike for zip around town.
