Product Description

Track your sleep, activity and food with the revolutionary UP band and mobile app. UP gives you meaningful, personalised, insights so you can make lasting improvements to your everyday life.

Live Better. Start Now.

Food & Drink
Track your sleep

Small and comfortable to wear all day and night, UP senses your micro-movements while you sleep and uses advanced algorithms to determine how many hours you slept, how long it took you to fall asleep, time spent in light vs. deep sleep and how many times you woke during the night.

Track your activity

Wearing UP captures a complete picture of your day, so you don’t have to guess how active you are.
UP tracks your steps, distance, calories burned and time spent active vs. idle.

Track your food & drink

UP’s mobile app lets you log what you eat and drink and get as detailed as you want.
Take a photo of your food, scan a barcode, browse the UP image gallery or search the ingredient database.
UP also helps you track calories, fats, carbohydrates, protein, sugar, fiber and sodium.

Gain insight

UP simply and beautifully visualizes your information so, at a glance, you can understand the meaning behind your data.
UP also delivers personalized insights and clear, actionable tips to help you achieve your goals.

Take action

UP helps you set daily goals and tracks your progress over time. It also lets you set helpful alarms and reminders. You can set a Smart Alarm to silently wake you at the ideal moment in your sleep cycle to help you wake up feeling refreshed. You can also set Idle Alerts to remind you to move when you’ve been sitting too long.

Share your success

Choose to share specific activity, sleep, individual meals and workouts to Facebook & Twitter.

Tl;dr: The 2 Ups I had, died after 6 weeks and 5 months; the average lifetime of this device is 100 days, and customer support is horrible.
I challenge you to Google "Jawbone up battery problem" before buying this product.

Had it for 6 weeks. The step counting was great and very motivating. The sleep tracking is nice in theory, but the sensor or algorithm that analyses it is not good - on nights when I had gotten up and walked 10 meters to the bathroom and back, the app would say I slept solid through the night and did not wake up once. How can it track walking around as "light sleep"?
The best compliment I can give overall is for the app actually - it is gorgeous looking.


After 6 weeks the device suddenly would not charge anymore. A soft reset and a hard reset didn't help. Jawbone apparently only has a US site (there was no UK or european site), so I contacted their customer support. 2 days later, got a reply describing some steps I should take to reset the device, and they asked where I had bought the band and if it had been exposed to water (it had not). I replied that the steps had not helped and the band was still not working.

No reply from them to that. After 3 days, I made a new case since they hadn't replied to my first one. No reply to that either. Then I found out, via hear-say on Google+ (since Jawbone keep this e-mail adress secret) they have a EU Support email adress and I emailed that, this time mentioning upfront I bought it via Amazon.co.uk and describing the steps I had already taken. Within 1 hour, I got a reply:

" Based on the information you've provided, your Jawbone device needs to be replaced. Please contact the original retailer where you purchased the Jawbone device to request an exchange.

Mine lasted for 14 months and now the button has stopped working so I cannot track sleep etc. It is now nothing more than a glorified step counter. It was great while it lasted but am certainly not going to buy another one. A few other friends purchased around the same time and theirs have also broken.

Bought Jawbone and loved it. Until it failed after about 6 months. Jawbone replaced it. The new one has lasted another 6 months and failed, just after the one year warranty. I shall not buy another one.

The weakness on both wristband is the button. When new, it actually clicks and you know it is working. With time, the action becomes less precise - seemingly as if the mechanism has retracted into the moulding although it may just be full of dried sweat. Eventually, you cannot press it anymore and the device is dead. Mine no longer responds to anything - no lights, even on charge.

This is a pity. The device is a good idea. But my wristwatch doesn't fail every six months so neither should modern, wearable technology. Luckily, there are now other options available to do the same - even a wristwatch

I love gadgets & I do believe that this type of technology is going to be the future key to health & wellbeing however the technology isn't there yet, the accuracy of this device is hit & miss, so much so that I've sent mine back for a refund as it just doesn't perform the way it should..... E.g. In the space of a week it has only once recorded my sleep accurately, most nights it tells me that I've woken up & stayed up around 4/5am which I know isn't true as I've actually been woken up by it vibrating on my arm at 7am. I did some research & found loads of other people complaining about the same thing with the suggestion being that perhaps it gets knocked out of sleep mode when one is moving about in sleep. Maybe so, but last night I put it to sleep mode at midnight & then read for a while so no moving around except this morning it informed me that I'd not turned it on until 3.30am. I'm not convinced the alarm function works properly either, unlike other reviewers I found that vibration was strong enough to wake me up but it always woke me at the absolute last time I gave it maybe because it had stopped tracking my sleep a few hours before! That said how was it even waking me up if I'd knocked it out of sleep mode?

Another inaccuracy is that I did an exercise DVD & straight after I plugged it in to see whether it had recorded the movement or if I manually needed to do so & it told me I'd achieved 100% for moving that day...... following day did the exact same DVD, plugged it in & it told me I'd only achieved 50% - that's a huge difference, a few percent I could have put down to me being a bit slack the second day but not half as much!

Great idea and I enjoyed using it whilst it lasted but they are dreadfully unreliable and as a company, they just don't care.

I've had 4 in 2 years, none of them lasted more than 6 months. Customer service is slow and sparodic and they just won't admit that they have a quality problem. They say they ironed out the problems from version 1, but they have replaced mine with version 2, just the same problems as described in other reviews here. Stops syncing, stops charging, button breaks, no amount of hard or soft resets will work.

Really don't bother wasting your money. They refused to replace my last one which was replaced last year, even though it was less than 12 months old (because my original was over 12 months remember.I've had 4). I offered to send my current one back so they could see the problem and improve there product, they were interested, I told them to look at the amazon reviews to see the amount of dissatisfied customers on this is there response below.

Thank you for contacting Jawbone Customer Care.

The UP wristband is an innovative product. There are no real problems of its reliability, but some units encounter malfunctions, fortunately they are not numerous. Many users of UP would not experience any problems whatsoever from the initial purchase. We are aware there are some negative reviews of the product online, however this would largely be the case for any product of this nature - that its faults would be highlighted first and foremost on a customer feedback forum or shop comments page.

Hello Nigel,

Of course I will collect your feedback.

Regarding returning you UP band, I think it is not necessary. Our development team has enough feedback regarding this particular issue.

If you have more queries, please, don't hesitate to contact us again.

Kind regards,

Jawbone Customer Care
