Jawbone’s newest activity tracker can measure REM sleep

Jawbone announced two new fitness trackers on Wednesday. Although there isn’t a firm release date yet, both the entry-level UP Move and the higher-end UP3 will be on store shelves by the all-important holiday shopping season.

Jawbone UP3

The UP3 is the direct successor to the UP 24, and like previous Jawbone UP trackers, it’s worn around the wrist and has a battery life measured in days — seven, when it first hits the market, and previous Jawbone products have received updates that improve battery life. Physically, it’s a more refined version of the UP24, with lights and a capacitive touch sensor on the top of the band, and a slightly slimmer profile that hugs the wrist better. It’s got a new magnetic charger, too.

It adds two new sensors to the familiar accelerometer: Sensors for measuring skin and ambient temperature, and four tiny contacts that make up a bioimpediance sensor. Unlike other fitness trackers, Jawbone hasn’t added an optical heart rate monitor to its wristband. But the new bioimpediance sensor on the UP3 will eventually allow Jawbone to track heart rate. To start, users will be able to track their resting heart rate — taken first thing in the morning because Jawbone can sense when a user wakes up — and eventually the UP3 will be able to provide heart rate information on demand.

The UP3 also builds on the sleep tracking features of previous Jawbone trackers, which were limited to data from an accelerometer. Using information from the new sensors, the UP app will have an improved sleep tracking interface, which has charts and specifies how much REM, deep, and light sleep a user gets. The bioimpediance sensor also opens the door for Jawbone’s app to quantify and track fatigue, stress and even hydration.

Jawbone UP3 clasp — it feels solid on the wrist but putting it on for the first time might be tricky

One of the most divisive aspects of the UP3 will be its new clasp. As opposed to the UP24, which came in three sizes, the UP3 is one-size-fits-all, and uses a new fastening mechanism that has a hook go into the band horizontally. It’s supposed to reduce pain and discomfort, but appeared to me to be overly fiddly — especially compared with the elegance of the UP24, which doesn’t even have a clasp.

Jawbone’s other tracker isn’t necessarily worn around the wrist, although it can be with an optional band. The UP Move is a disc-shaped accelerometer step tracker that can sync with the UP app as well as display your progress toward your step goal in lights. In terms of features, it will match the fitness tracking capabilities of the UP24 but lacks notifications and IFTTT integration. In concept, it is similar to the Misfit Flash, another disc-shaped activity tracker that costs $50. The Jawbone UP Move won’t require daily charging — it’s got a built-in battery that should last six months before it needs to be replaced.

Jawbone’s products are designed by Yves Behar, and they largely reflect his design sensibility: That once used, good design should become almost invisible to the wearer. That’s why the UP3 has a seven-day battery life, for instance, so there are fewer reasons to fiddle with it and the user can forget about it and wear it to sleep or in the shower. If you’ve got questions about his “invisible design” approach to wearable technology and Jawbone, Behar is going to be speaking at Gigaom’s Roadmap design conference this November.

The Jawbone UP Move will cost $49.99 and the UP3 will cost $179.99 when they go on sale “later this year,” although Jawbone isn’t providing an exact date. The existing Jawbone UP24 tracker isn’t going anywhere, and pricing-wise, it will fit comfortably in between the two new trackers at $130.

Was it tested on people with sleep disorders such as Sleep Apnea or Better yet with neurological disorder such as people with Narcolepsy to see how accurate the sleep stages are???

I’m having REM Sleep feature in my Basis Fitness tracker for quite a few months !

The old one broke on me constantly. Have had two replacements and after the next broke after a few months, I called it quits with them.
