It’s a better system than the Up24’s plug, though, since there’s no more stupid charging cap to lose.īut cost might be the most important part of the Up2: it starts at $99.99. They’re external now, but you have to align it the right way for the magnets to catch. The charging contacts also theoretically shouldn’t preclude waterproofing. There’s no heart rate monitor, so there’s no good hardware reason beyond cost not to waterproof this thing. It’s fine for sweat or rain or the shower, of course, but to be honest I’m really shocked that Jawbone couldn’t make this more useful for swimmers. Unfortunately, the Up2 isn’t totally waterproof, just water-resistant. Unlike most smartwatches, you don’t have to think about charging it every night, and you can leave it on for sleep tracking. Among smartwatches, only the Pebble comes close to that, and it can’t do the kind of advanced fitness tracking the Up2 can. I’ve got about two more days left, according to the app. I’ve had it on for a week and haven’t charged it a single time. The best part about the hardware? The battery life. Like the clasp, it’s fussy, and after a day or two I stopped bothering with it. For two, interacting with the Up2 requires you to use an unintuitive double-tap-and-hold-your-finger-down gesture to switch from active to sleeping modes.
#JAWBONE UP24 SIZER SOFTWARE#
You don’t need to, for one, since the software usually guesses whether you’re exercising or walking or sleeping on its own. It’s a good thing the software on the phone is so good, because interacting with the Up2 itself is kind of pointless. You can enter your meals in too, if you really want to track those. You can program in little "get up and move around" alerts. You can program smart alarms that set the Up2 to vibrate when you’re coming out of a deep sleep. It automatically figures out whether you’ve been sleeping or exercising and alerts you when you want it to so you can enter the relevant info on your workouts. It tracks steps, sure, but the real magic of the Up2 (and with any Jawbone fitness device) is the Up software on your phone.

The whole point of the Up2 is to quietly track your basic physical activity, a job it tackles without hassling you. I guess the best thing I can say is that it encourages me to leave the little thing on my wrist. But the thing you do more often is, you know, clasp it, and I find it’s fiddly and kind of annoying. The design does a nice job of being attractive enough when you look at it, but nondescript enough that you don’t have to. I like the crosshatch pattern, and I like that the three indicator lights are hidden underneath it, only lighting up when you need them. Like the Up24 before it, the Up2 was designed by Yves Behar to have an attractive aluminum casing. But more than raw size is the design: it has a more comfortable, more flexible strap and a better-looking module for the electronics. The Up2 is small - Jawbone says it’s 45 percent smaller than last year’s Up24, and I believe it.
