Another interesting aspect of the Up application is its social component. The software lets you search for friends with Up accounts and then invite them to become a member of your team. Once linked, team member performance is listed in a real-time social feed on the home screen.
Like the Fitbit, the Up offers a way to log your meals. You can select food from a small variety of common items arranged in categories such as drinks, breakfast, and snacks, each with a lovely stock photo, or you can search for an item manually within the Up database. With tight iPhone integration, however, users can also scan bar codes of consumer goods or simply snap their own photos with their handset's camera. Unfortunately the app lacks a way to measure calories consumed directly against calories burned.
Another of the Jawbone Up's notable capabilities is an idle alert feature that you set within the app. The band will vibrate when it detects that you haven't moved after a predetermined interval, 30 minutes or an hour. This haptic feedback can also serve as a silent alarm to buzz you out of bed and not disturb your partner.
Need more sleep? That's not an issue, either, since pressing the Up's button twice and then holding it down activates Power Nap mode. After a time determined by how much sleep the Up thinks you need, the band will vibrate to gently nudge you awake.
Data geeks will find a friend in the Up as well. Under the Lifeline section of the app, a full timeline is displayed with complete stats for activity and sleep, plus markers for when you achieved personal goals. Moods logged are showcased here as well. Additionally, the Trends feature provides a deeper dive into your data. Simply select from a number of data criteria such as total sleep, deep sleep, steps, and calories burned, and plot them against each other over time (in days, weeks, or months).
Out in the field, the Jawbone Up performed pretty much as advertised, though I did have problems with the first test unit I received, which likely suffered from a faulty battery. That said, it was a prerelease model and my replacement operated just fine.
As it's both comfortable and lightweight, I was able to wear the Up band all day long for days on end. I also showered with the gadget many times with no problems.
The Jawbone Up also seemed accurate to me, whether on walks or runs at the gym, recording step-based exercise in line with what I've observed from the Fitbit Ultra and Fitbit One products. I personally appreciated that the Up wasn't thrown off by fatherly activities, too, such as pushing strollers, even though the product remained stationary rather than swinging from my arm. Barflies, coffee nerds, and other beverage fanatics should note that the Up band didn't register fake steps when I raised my arm to drink -- something the FuelBand was prone to.
The fact that I could have the Up strapped to my wrist made a huge difference as well since it was always handy to log sleep intervals. Actually the device was almost too convenient for recording my restful hours, or shall I say painful and chronic lack of them. Well, nobody said parenting twin toddlers was going to be easy.
Both the Power Nap and idle alert functions were simple to activate and set up as well. Logging food was trickier, since many of the items I tried to record were either homemade or not from big chain restaurants. Know how many calories are in the No. 25 sandwich special from my local Vietnamese joint? Yeah, me neither.
The biggest strength of the Up is its long battery life. Jawbone rates its rechargeable battery as being able to power the device for up to 10 days. That said, I managed less than that, getting about seven days from the product. Of course that was during heavy usage during my test period and performing multiple syncs each day.
What the Jawbone Up isn't, however, is a fully loaded fitness device for exercise enthusiasts or professional athletes. For example, while I could log workouts either manually or by kicking the device into stopwatch mode, it won't measure speed or distance traveled. For that you'll have to spring for a GPS-equipped fitness tracker like the Motorola MotoActv.
