What is the Jawbone UP24?

The Jawbone UP24 is the Jambox-maker’s second wrist worn activity tracker aiming to whip you into shape whether that’s pushing you to do more exercise, eat healthier food or get a good night’s sleep.

Set to live alongside the Jawbone UP which is now priced at £100, for an extra £25 the UP24 now adds Bluetooth Smart syncing with iPhones and Android phones so you can view data in real-time.

The Jawbone UP was not without its issues when it launched back in 2011 and with the likes of Samsung, LG and Sony now trying to tap into the fitness tracking movement, is there enough of an improvement to make the upgrade to the UP24? We slapped it around the wrist to find out.

Watch our video on the Key Features of the Jawbone UP24

Jawbone UP24: Design

Aesthetically, the original Jawbone UP is still one of the sleekest and most stylish bands around so it’s no surprise to see that the UP24 doesn’t get a drastic design overhaul. It’s still made from a textured rubber but now has a swirled pattern design where the ends snake over each other to create the grip around the wrist. Jawbone says it has used a hypoallergenic and medical-grade rubber so you shouldn’t, in theory, encounter any Fitbit Force-like skin irritation issues.

It still comes in three sizes small (19g), medium (22g) and large (23g) making it lighter than the smallest version of the Fuelband SE (27g). Bending the band and submerging it in water are still off limits as well so it’s clear that the insides of the UP24 have largely remained the same.

On one end of the band you’ll find the syncing button to set up a Bluetooth connection and switch between day and sleep tracking. Jawbone is still resisting on including a built-in screen so once again you’ll need to rely on your smartphone for a quick review of data collected. Jawbone does include two single green LEDs that light up with either a little crescent moon or flower icon to indicate the tracking state.

The other end of the band hosts a cap that hides away the 2.5mm charging connector. This does unfortunately mean you are stuck with Jawbone’s headphone jack-style USB cable to power up the UP24, rather than a more universal alternative. Unlike its predecessor, though, the cap definitely feels altogether more secure and less likely to fling off.

It’s now only available in either orange or charcoal black colours but it remains one of the slimmest and most unobtrusive bands to wear during the day and at night. It doesn’t shout ‘fitness tracker’ in the same way that the Nike Fuelband SE, the Fitbit Force or Fitbit Flex do, and for some people who want to keep tracking more discreet it definitely has that appeal.

Jawbone UP24: Features

Tracking all of the data is done via the Tri-axis accelerometer, technology that’s similarly found in the Nike Fuelband and the Fitbit trackers. The biggest change of course is Bluetooth Smart syncing. The benefits of having the newest Bluetooth standard support on board is the ability to exchange data in real-time without draining the battery life on your smartphone. It also means you don’t have to plug the band into a computer to sync the data.

That data is still focused on the step counting information that a standard pedometer records and sleep tracking with a new sleep recovery mode as back up when you forget to sync. You can also log food consumption and workouts to build a more comprehensive view of your day. There’s a lot of data to take in so the aim of the Jawbone ecosystem is to make better sense of that data.

One of way of doing this is by using Jawbone’s Insight engine. Perhaps the most intriguing of the new software tweaks, the company has invested in a data science team to analyse personal data and make recommendations to improve step count and sleep time. These recommendations come in the form of little information cards that appear in your UP news stream after data has been collected for at least four to five days.

Jawbone also sends out an email every Monday giving you a summary of the previous week’s step and sleep averages. At the bottom of the summaries we were reminded that good sleep requires a dark room and to think small about making improvements whether it’s going to sleep 30 minutes earlier or walking when taking phone calls. All reasonably sound advice but not entirely what we would call tailored information.

You don’t have to rely on Jawbone’s suggestions to decide to take action. There’s plenty of new software additions to take more a proactive attitude towards improvement. The pick of the bunch is the new ‘Today I Will’ feature that makes you promise to sleep, move or drink more water.

If you are struggling to keep track of all the activities you promised to - like getting ready for bed earlier, going for that run or you’ve been inactive for too long - you can get a nudge by setting up alerts and reminders. These can either be through phone notifications or sending a vibrating buzz on the band.

I have owned and used the Jawbone Up for almost a year and I'm very disappointed. The idea of the band was a good one, but the execution of that idea falls flat. So many problems: (1) In order for it to record your sleep, you must push a button when you go to bed and push it again when you get up. If you forget to push the button it does not record your sleep. That is a simple fix in the design programming, but they failed to design it to detect when you go to sleep or get up. (2) Once you download the software, you cannot alter or change your entries, like if you make a mistake in typing, or simply want to start over. It matches up with your email address, so if you want to start over, you have to delete the software from your computer/phone, reset the band, and re-enter it with another email address. If you enter the same email address, the old data reappears on your log again. This is ridiculous. (3) The biggest flaw in the design is that it does NOT measure your activity accurately. Since the band is on your wrist, if you wave your arms around, it thinks you are moving. I tried an experiment. I walked briskly for 30 minutes without moving my arms. Then I did arm exercises sitting on the couch for 30 minutes. The band recorded the arm movements as exercise and did not record the walking as activity. That is a MAJOR FLAW in the band! It should base the activity on your elevated heart beat not on whether you wave your arms around or not. (4) There is no way to record data at a later date. For instance, if you fail to push the button to record your sleep, and you are busy during the day and the time rolls past midnight, you cannot enter the data for the day. Same thing with food; if you forget to log in something, at midnight, the opportunity to enter for the prior day is gone forever. If you have a busy life, this is a major drawback. (5) Finally, it is poorly made. I took very good care of my band and yet it started to fall apart 90 days after I started wearing it and by the ninth month, it had stopped charging and the cover that attached over the plug would no longer attach. It did not even make it to the one year anniversary of purchase. I would NOT recommend this band. You will not only be disappointed, but frustrated with its inadequacies.

As an FYI on points 2 and 4 - the new app allows you to record your sleep even when you don't push the button. You can do this days after for multiple days.

They fall off. We had 3, all fell off when removing clothing so beware

I have had the jawbone up 24 for less than a year and had to replace it two times already. None of the jawbones lasted more than several months (3-6 months each). I got jawbone to replace it each time, but at this point, I think I'm just going to give up on it. I took good care of my jawbone too. My boyfriend got one at the same time as me and even though his jawbone lasted longer than mine, it didn't even make it to a year either.

i'm using the jawbone for a month now and it was working just fine.... Until i bought a Harley Davidson. since then, it seems that the sensors got crazy! for a 2 miles trip on the bike from home to work, its recording like 3000 to 5000 steps! the motorcycle exhaust vibrations are considered massive steps for the band! so by the end of the day i look like a marathon maniac and an above normal calorie burner, if it continues like that, the band app should declare me dead in a week!.
Am thinking of giving it to my brother!
jawbone and motorcycle are not compatible!

If your Harley davidson is one with a keyless start and only requires the fob to be on you somewhere, there's your issue. Bluetooth interferes with it and the motorcycle maker recommends keeping cell phones turned off during riding these motorcycles so this could be your culprit.

I purchased the 24 UP in October 2014, and it worked up until this past weekend. It then stopped syncing, then charging (it is still plugged in), and then stopped communicating with my iPhone. I wrote the company at mobile support@jawbone twice, and have received nothing from them at all. the unit is still plugged in, but no charge or functioning at all. this is disappointing, and makes me not want to purchase anything from this company again...

UP24 is TOTALLY unreliable, just look at this, and other forums...

A complete waste of money, mine stopped working after one month, so I reset it, and lost all data (handy), it worked again for nearly 2 days!!! Broke again, BEYOND frustrating, tried everything, soft reset and hard reset, re-synced it, re-started apps, deleted app, syncing it with another device, but nothing. And I'm not alone.

They should stop selling them until they can sort out the bugs.

Be warned!

Mine worked for about a week and even then it was spotty. Returning it took six weeks of emails, headaches, and jumping through hoops because "their warehouse did not receive my package". I had to get a confirmation document from the post office before they would refund me. Don't even bother.

Unbelievable, but UP24 detects REM sleep phases. No doubt.
