Jawbone Up 24 Review – Specs, Sleep Tracker, Price

Jawbone Up 24

The wearable tech craze started sometime back in 2013, Jawbone, to keep up with the trend, came up with a wristband of their own: the Jawbone Up (predecessor of the Jawbone Up 24) which did fairly well in the then young market. Save for the poor architecture, aesthetic, no display, lack of wireless connectivity and iOS-only compatibility, the gizmo was an above average effort, to be very honest, and deservedly ranked as one of the finest fitness trackers of its.

What is a UP24?

Jawbone Up 24 With the new Jawbone Up 24 though, a number of those shortcomings have been meticulously addressed. Ok, nothing much has been done to the design as the band still bears its predecessor’s look, but there’s a lot to acknowledge in the functionality facet.

For one, to read your activity stats, you don’t necessarily need to take off the band and plug it to your smartphone anymore; the new fitness band connects wirelessly and syncs automatically with your smartphone as long as you have the Up app running. Here are a few more differences between the Up and the Up 24.


  • Light and deep sleep data
  • Wireless syncing
  • Water resistance
  • Slim unobtrusive architecture
  • Smart alarms for naps
  • Idle alert/Sedimentary alarm
  • Great App design and interface
  • Longer battery life than most competitors, though lower than the Up’s
  • Smoother band ends, which were too protrusive and sharp in the original Up
  • Both iOS and Android compatibility


  • No display, which translates to no immediate feedback. Dependent on phone to read data.
  • A good smartphone app but no website interface
  • Hair can easily get caught in the cap
  • May over-count steps sometimes due to irregular arm movements

Jawbone Up vs. Jawbone Up 24

Jawbone up 24Beginning with the price, the Up 24 goes at around £35, roughtly the same as the UP these days. The Up 24’s battery can sustain charge for an estimated 6-7 days, three less than the Up’s maximum, and this can be validly put down to the more charge-consuming features sported in the new band.

Sync Jawbone Up 24

On syncing, the Jawbone Up 24 is easier to sync than an average fitness tracker, while the Up generally has below average syncing capabilities, based on the PC and mobile device syncing technologies used and whether or not the band syncs automatically. The Jawbone 24 Up syncs automatically, the Up doesn’t.

Jawbone Up 24 Design

The Jawbone 24 Up, as pointed out earlier, isn’t any different from the Up, from an architecture perspective. It’s a simple, inconspicuous band that’s been designed to curl around and fit perfectly to the wrist without the aid of a clasp.

For the record, this means that we have the Jawbone Up 24 small, medium and large versions for all wrist sizes.

Jawbone Up 24 Colours

Jawbone Up 24 also comes in six different colours:

  • Persimmon (orange) lemon lime,
  • pink coral,
  • onyx,
  • blue,
  • green
  • and shiny grey.

They may seem too loud but practically the slim design provides little room for unwelcome glitziness.

11 Things You Can Do With Jawbone UP

Jawbone Up 24Even without a screen, the band still sports spot-on delivery with a single button that does virtually everything. To tell the current mode, awake or sleeping, you only need to tap the button once, and a signature vibration will be produced.

By long-pressing the button, you will be changing the mode (the sun and moon emblems displayed stand for awake and sleep modes respectively)and be able to toggle between the modes. One-time tapping followed by long-pressing starts the stopwatch while double-tapping and holding the button opens the Jawbone Power Nap Mode where the band gives you a maximum 60-minute “nap-time” before waking you up (with an alarm, of course).

1. Jawbone Up 24 Activity Tracking

Most of the fitness trackers, especially the earliest ones, only count the number of steps you make, and the Up 24 is no exception. It can be really effective and motivating for people who want to increase their work rate but then lack of a heart rate monitor, for instance, or just another mode of measuring activity, besides counting number of steps, does heavily count against the fitness tracker’s usefulness.

2. Jawbone Up 24 For Cycling or Gym

If you have to do some squats, a set of heavy or lighter ones for stronger repetitions, without actually moving or making steps, it would be useless to have the band on. Or, maybe you’re cycling, and are having spells of long rides; much of your activity is likely to go unrecorded as your arms remain fixed to the handle bars throughout the sessions. It’s arguably the biggest downside of this kind of fitness trackers, but you can be guaranteed of accuracy and reliability if counting steps is the main reason you would like to have this band.

On the credit side, the Jawbone Up 24 has been designed to motivate you to get more active in one very interesting way. Using the app, you can set the band so that if you go inactive for a certain length of time, say, 1 hour, it makes a pattern of vibrations as a reminder that you need to get back to work. Trust the pedometer tracking to give the exact number of steps you make daily, and to motivate you to try and meet the default daily goal of 10,000 steps.

3. How Does the Jawbone Up Track Sleep?

Sleep tracking is one of the main reasons most people want to have a fitness tracker. Just as the hype suggests, the Jawbone Up 24 delivers some of the most accurate nighttime data compared to other trackers. It surprisingly has the capability to differentiate between deep sleep and “sound” or light sleep periods.

Although sleep tracking doesn’t necessarily help make any changes in your life, it’s interesting to wake up in the morning and see not only how much you’ve slept, but also how much sound sleep you’ve had. It tells you if you’re a good sleeper, at the very least, and can help you make appropriate daily activity adjustments so that you get as much sound sleep as you need.

It’s easy to relate the sleep data on the app with the previous day’s activities, and this can help you point out the reasons behind too little, or even too much sound sleep. You may have had too much of something – coffee, alcohol or anything – and realised just how much sound sleep it carts off your programme.

For these reasons, the Jawbone Up 24 may be a very helpful device to have.

4. Idle Alert

Jawbone Up 24

This can be tuned to meet your goals/needs. You can set the band to remind you to get moving every time you’re inactive for a certain period of time. So, if you’ve set it to alert you after 1 hour of inactivity, and you’re seated in your desk for an hour or more, the band will let out slight vibrations, which should be a nice excuse to get up and grab a glass of water or coffee, go release yourself, or even take a short walk in the backyard.

Sometimes, however, such as when you’re driving, the alert becomes irrelevant and has to be ignored, making it somewhat an imperfect system.

5. How to Take a Power Nap with Jawbone Up 24

Daytime napping has numerous health benefits, according to health experts, but then sleeping too long may be detrimental, especially if you have a tight schedule.

There’s also the possibility of feeling groggy if woken by a loud alarm while you’re in deep sleep, and that’s where the Jawbone Up Power Nap feature comes in. The band, with the help of this feature, not only ensures a soft vibration rouses you and not some piercing alarm tone, but also does it at the perfect time – during a light sleep cycle. The moment it notices you’re in light sleep, it gives you a slight buzz on your wrist, and up you get.

7. Stopwatch

This is one of the least useful features of the Jawbone Up 24. You can still use it though, but then it’s somewhat counter-intuitive that a device with no display has a stopwatch. If you need a realer stopwatch, then you can just use your phone. Furthermore, you’re going to use your phone to set the stopwatch, so what’s the use? But if you’re having a walk, run or hike and doesn’t want to carry your phone with you but wish to time yourself while you’re out, the fitness band’s stopwatch may come in handy.

8. Smart Alarms

With this feature, you can set a string of alarms for the whole week based on your activity schedule. For example, you’re free on Tuesday and Thursday mornings and would like to get your workouts before leaving for work at 9am. Rather than setting your phone or an alarm clock to wake you up ahead of everyone else, you can set a smart alarm on your band, and when it’s time to wake up, the band will vibrate to rouse you without anyone else in the room or house hearing a thing. What’s more, the band doesn’t need juicing up every 48 hours like your phone.

The real reason it’s called a smart alarm is because you can schedule a specific period of time when the band will vibrate and wake you up during a light sleep cycle. If for example you set your alarm for 5:00am with a “window” of 15 minutes before or after 5:00, the band will wake you up any time between 4:45am and 5:15am when you’re in light cycle of sleep. If you’re in deep sleep throughout the window, the band will wake you up at the last minute, which is 5:15 in this case.

9. Reminders

The reminders feature works the same way as the smart alarm. If you want to time your snacks at certain intervals during the day, or want to set the time when you can go out for a walk with your dog and a friend, you can set a reminder which will let out a signature vibration pattern on your hand and display the alert on your phone.

10. How Long Does it Take to Charge a Jawbone Up24?

Charging is via a jack plug similar to the one used in the old Up band, only that this one is 1mm thinner. Charging to 100% only takes less than an hour and a half. You only need to juice up the unit once in a week, which facilitates easy week-long activity tracking.

The differences between the Jawbone Up24 and the Up do not extend to charge time, though, as both of them take an approximate 80 minutes to charge fully.

11. Is the Jawbone Up24 Waterproof?

Regarding waterproofness, Jawbone describes the Up 24 as only water resistant, which means the app can withstand small splashes, a shower, and light rain, at the very most, but not submergence.

That said, lack of a display remains the fitness band’s biggest letdown. It simply means you must bring your phone with you during gym sessions and runs if you’re going to need the clock or some real time notifications and alerts. Jawbone did try to make up for that weakness, though, by fitting the band with a few LEDs that alert you on mode change and charge status, but a screen would still work better.

The Jawbone Up App for iPad (iPhone) and Android

Jawbone Up 24 AppThe iOS-compatible app has a nice design, runs pretty well and sports the easiest of interfaces. It does fail to locate the band automatically at times, though, according to some users, but runs really smoothly for the most part.

Running the app in your iPhone all day for real time notifications also does help drain the band’s battery real quick because Bluetooth is constantly running, but you can reduce this by sporadically opening the app to check your progress and closing it once data gets synced with the app.

As an added bonus, the app displays a few motivational quotes on the home screen as it starts each day, which can act as your training tips as well (I can’t promise that, though).

Jawbone Up 24 vs. Fitbit and Competition

Yes, the Jawbone Up 24 doesn’t have a screen, which is very bad news for many users. But compared to what its biggest market rivals –Fitbit Flex, Misfit Shine and Nike FuelBand SE – have to offer in terms of features and functionality, the little wristband is a hands down winner and perfectly justifies its £35 price tag. A lot of its success is mainly thanks to the Up 24 app which displays data in an awesome “news feed” style, but there are other features on the band itself that make it the best of its kind.

The most useful of all, probably, is the tracker’s one button, which shuts it down as the user sleeps and starts it each morning, with LEDs that keep you alert on what’s going on.

Shine has a very unsophisticated app, and is quite unresponsive, the FuelBand has no Android app altogether, while Flex sports an uncomfortable fit.

The Up 24 is not perfect either. Its design, I maintain, is a major letdown and it looks wanting, but on the whole, the band is efficient, gives you value for your money and is worth a try.
