Jawbone Sleep Tracker: Understanding Its Functionality And Features

The Jawbone UP MOVE Wireless Activity Sleep Fitness Tracker is a device that can track your sleep, as well as your steps, calories burned, and overall activity. The tracker can be worn on the wrist, with a clip, or a strap. The Jawbone UP MOVE is compatible with both iOS and Android and comes with an LED display that indicates the time and progress towards your fitness goals. The tracker also comes with a Smart Coach feature that learns your habits and gives you personalized suggestions to help you get to bed on time.

The Jawbone UP24 tracker's design

One of the most significant design aspects of the Jawbone UP24 tracker is its collaboration with designer Yves Béhar, the company's Chief Creative Officer. Béhar's design philosophy is evident in the tracker's quirky aesthetic, incorporating brightly coloured plastics that not only serve a functional purpose but also make a bold fashion statement. This unique approach to design set the standard for future fitness trackers, blending style with functionality.

The Jawbone UP24 tracker also introduced wireless syncing capabilities, a feature that is now commonplace in the industry. This advancement eliminated the need for manual data syncing through a physical connection, streamlining the user experience. The tracker seamlessly integrated with a companion app, providing users with a user-friendly interface to track their fitness goals and progress.

Additionally, the Jawbone UP24 tracker's design included a refined and sleek form factor. While the specifics of its dimensions are not readily available, it is known for its slim and stylish design, ensuring comfort and discretion during wear. This design consideration has become a key differentiator in the fitness tracker market, where consumers seek devices that are unobtrusive yet aesthetically pleasing.

Furthermore, the Jawbone UP24 tracker's design incorporated automatic sleep tracking. This feature, introduced in subsequent models like the UP2 and UP3, revolutionised sleep monitoring by eliminating the need to manually activate sleep mode. This enhancement contributed to a more seamless and accurate tracking experience, allowing users to gain deeper insights into their sleep patterns without any additional effort.

How it tracks sleep

The Jawbone UP MOVE Wireless Activity Sleep Fitness Tracker is a clip-on or strap-on device that can be worn anywhere on the body to track sleep. It has an LED display and a Smart Coach to guide you. The UP MOVE tracker counts steps, tracks sleep, and monitors overall calories burned throughout the day. It also has a companion app that provides a bar graph with two metrics: steps and sleep progress towards 100% of your targets. Push notifications inform you if those goals are met or how you slept on previous nights.

The Jawbone UP2 is another Jawbone device that tracks sleep. It has a crosshatch pattern with three indicator lights hidden underneath it, lighting up only when needed. It automatically figures out whether the user has been sleeping or exercising and sends alerts to enter relevant information on workouts. The UP2 is water-resistant but not waterproof, and it does not have a heart rate monitor.

The Jawbone UP24 is a successor to the UP2 and offers wireless syncing to the companion app via Bluetooth Low Energy. It does not have the ability to cross-reference step data with heart rate and GPS, but it can judge sleep length based on the infrequency of the user's movements. The UP24 also provides distance and calorie data from the built-in 3-axis accelerometer.

The Jawbone UP has been evaluated in studies and shown to have high sensitivity in detecting sleep and good overall agreement with polysomnography (PSG) measures. It overestimates PSG total sleep time and sleep onset latency and underestimates wake after sleep onset, with greater discrepancies on nights with more disrupted sleep.

How it tracks activity

The Jawbone UP MOVE Wireless Activity Sleep Fitness Tracker is a device that can be strapped on to your wrist or clipped on to your clothes. It tracks your steps, calories burned, and sleep. It has an LED display that shows the time and your progress towards your goals. The tracker also comes with a Smart Coach feature that learns your habits and gives you personalised suggestions to help you achieve your goals.

The Jawbone UP2 is another Jawbone fitness tracker that can be strapped onto your wrist. It automatically tracks your basic physical activity and sleep. It has three indicator lights hidden underneath a crosshatch pattern that light up when needed. The UP2 software on your phone automatically figures out whether you've been sleeping or exercising and sends you alerts so that you can enter the relevant information about your workouts.

The Jawbone UP24 is the successor to the UP2. It features a refined design and a host of new features while resolving some issues with the original 2011 device. The UP24 does not have a heart rate monitor or GPS, but it can judge sleep length based on the infrequency of your movements. It also has a 3-axis accelerometer that calculates the distance travelled and calories burned.

The Jawbone UP has been evaluated in studies for its effectiveness in tracking sleep. One study found that the Jawbone UP had high sensitivity in detecting sleep and good overall agreement with polysomnography (PSG) measures, making it a feasible alternative for monitoring sleep-wake rhythms over several days. Another study found that the Jawbone UP overestimated sleep efficiency and total sleep time while underestimating wake after sleep onset compared to PSG in a group of 65 adolescents.

The tracker's compatibility with other apps

The Jawbone sleep tracker is compatible with other apps, such as Sleepio, which is a "clinically proven sleep improvement program". Sleepio offers cognitive behavioural therapy (CBT) sessions that provide advice on improving your sleep efficiency (SE) – the total time spent asleep as a percentage of the total time in bed. Sleepio also provides a simple online diary where you can input additional information about your sleep habits.

The Jawbone UP24 was also the first in the range to offer wireless syncing to the companion app via Bluetooth Low Energy. This allowed the device to integrate with other apps that tracked exercise, caloric intake, and even water consumption.

The Jawbone UP MOVE Wireless Activity Sleep Fitness Tracker is compatible with both iOS and Android. The Jawbone UP app is also available for iOS and Android. However, one source notes that the Jawbone does not connect to any other apps or devices.

The tracker's limitations

The Jawbone sleep tracker has several limitations. Firstly, it does not have a heart rate monitor, which is a feature offered by competitors such as Fitbit. This is a notable omission as heart rate data can contribute to deeper sleep analysis. Secondly, while the Jawbone UP2 is water-resistant, it is not totally waterproof, which is a drawback for swimmers. The UP3 model was intended to be water-resistant, but this caused long engineering issues and was eventually abandoned.

Another limitation is the clasp, which some users have described as "fiddly" and "annoying". The UP3 model also suffered from an "awkward, cheap clasp". In addition, the Jawbone sleep tracker has been described as dated compared to newer models on the market, and the company that produces it is going out of business, which means there won't be any support for the product.

Despite these limitations, studies have shown that the Jawbone UP provides acceptable levels of agreement with PSG measures when the overall night is considered. It may be a feasible alternative for ecologically monitoring sleep-wake rhythms over several days.
