Size: Medium (6-7 inches)Package Type: Standard PackagingColor: Persimmon
Last November, I reviewed the Jawbone UP, and later compared it to the Fitbit Flex. A year later, Jawbone has now released the UP24. This review will primarily focus on making a choice between UP, UP24 and Fitbit Flex. When I originally reviewed the devices, I thought the main differences would be in the hardware appearance and fit/feel. I was a bit wrong-- the biggest functionality difference was in the quality, function and aesthetic value of the software that comes with it. With the UP24 now having bluetooth syncing, the biggest difference for me is now only the software. I'll let you make your own conclusions.

And now a year later, I will refresh my thoughts about the UP & Flex devices, and how the UP24 adds to the mix of options.

Hardware Comparison
UP24, UP and Flex are equally easy and comfortable for me to wear. The Flex requires a bit more work to latch, and the UPs both can get in the way when keyboarding on a laptop. Flex is charged by removing a horse pill sized module from the rubber arm band, and plugging it in to USB. UP is charged by plugging the band into an adapter and charging in USB.

First off, I would like to point out that I own both the Jawbone UP24 and the Fitbit Force and will compare a few features in this review, but if you want a full review on the Fitbit Force I will be posting one on the actual product here soon.


The UP24 features new curved design on the top, has a smaller headphone jack that is only used for charging, and now syncs via Bluetooth. It has two green LED lights indicating day/night mode, a vibrating motor and a physical button for changing modes.
There is no clasp, you just twist it on and it fits fairly comfortably if you chose the right size. It is thin and bulky so it tends to get in the way and raise my wrist when I type or use a mouse and can get annoying, I prefer a wider, flatter design.

The Fitbit Force has a beautiful OLED Screen that shows you all of your stats without having to pull out your phone. The design is very minimalist, and to me is much more comfortable to wear vs the UP. It also does not snag on my jackets or long sleeve shirts and is very thin at the bottom so it is comfortable to type with it on where as the up can be very uncomfortable to type or use a mouse with it on.

Battery Life - Battery lasts me about 7-8 days and takes about an hour to charge. The manual says to charge it only on a USB port on your computer, but I have charged it using my iPhone wall charger and car charger just fine.

Pedometer - The UP seems fairly accurate for tracks your steps. If I wave my arm around or if I'm driving, the UP does not count steps whereas the Fitbit Force seems to count steps for any slight movement I make.


The App is just plain beautiful and intuitive. It is indeed what makes this product what it is.

Size: Medium (6-7 inches)Package Type: Standard PackagingColor: Onyx
I was initially given the Up24 as a Christmas Gift. My fiancé saw that I had been searching for weeks trying to decide the right one. She did some research on her own and decided to get me this product. But after a week, I returned it and brought the Nike Fuelband SE. BUT here is my product review.
1. Software: The Jawbone’s software is FAR ahead of Fitbit and Nike Fuelband. It was very comprehensive and easy to understand. The Software integrated with all the popular Fitness tracking apps, i.e. Myfitness Pal. Fitbit does too. Nike Fuelband does NOT! That’s a huge negative for me. I digress. The software automatically synced with Myfitness Pal. What I would offer as a suggestion to Jawbone is to improve the software would allow for the individual to put in Calories manually. It allows it, sort of. But you have to do some playing around. ALL, I REPEAT ALL, Fitness trackers are horrible at recording Weight Training and Static Exercise Machines (treadmills). BUT jawbone does better than all to help the user put the actually calories that they think may have burned and sync with MyFitnessPal.

2. Sleep tracking: Another good one. Their sleep tracking and integration was awesome and provided me an insight into how I sleep. I noticed that I do my heavy sleeping early and light sleep as the night wears on. I think that is military training. I digress.

3. Battery Life: 7 days is great. Before I decided to switch, my plan was to wear the device Monday-Saturday and take it off on Sundays for charging. I personally believe that too much tracking and syncing will derail your fitness plans. Need to give it a rest. No matter. This is still a plus.

4. Ease of use. Very easy to remove and expands.

We understand how fit can be a big factor when deciding on the right fitness tracker! We offer the UP and UP24 in a variety of sizes (Small, Medium and Large) to accommodate all wrist shapes and sizes and we're sorry to hear that you're weren't able to find a fit that felt comfortable.

The Food logging portion of the UP app is something we have been looking to improve for some time and we are excited to announce we've just released an update (version 3.2) to the iOS UP app that has completely redesigned the Food Logging experience! Users are able to easily create custom foods with detailed nutritional information like Calories, Saturated Fat, and Fiber. More information about this new Food Logging Experience please see this link: https://jawbone.com/up

Thanks again for posting your review!
