there are a few fitness trackers that we've liked more than others the jawbone up has always been one of them in the up three was announced back in November we were waiting for it when was it going to arrive integrating heart rate tracking into a little band it's finally here and that's not it jawbone has also unveiled another band the up two which is this which looks a lot like the up three that's on my wrists they're smaller they are easier to charge and what else do they offer well one has heart rate tracking and one doesn't and that's the big difference between these two the up two is a replacement to the up 24 which has bluetooth syncing basic fitness tracking steps sleep walking and buzzes to remind you of things just like previous jawbone bands the new up tune up 3 do not have displays they basically look like regular wristbands they have tiny icons that light up if you tap to tell you about whether you're in sleep mode or activity tracking mode the up 3 adds bioimpedance for its heart rate monitoring which is different than optical technology and the difference there is that not only can it provide heart rate tracking but it has galvanic skin response ambient and skin temperature and jawbone claims you may be able to do stress reactions and other types of input related health measurements as time goes on interesting kind of an unknown territory unless you've used body media which used that same technology in another wearable these feel pretty light on my wrist the clasp is a lot harder to attach than the old band which was iconic but a lot of people found a tended to break was a little strange with the springiness and came in several sizes it also had that cap on the end which was really annoying there's no more cap it's one size fits all but you have to deal with attaching that clasp and it's got a cool new charger that's magnetic so you could plug this right into the wall and have it glom right on pretty easy to use both of them last about a week the jawbone up 2 and up 3 are going to be available to order now the up 2 is $100 the up 3 is 180 us only for the moment Global eventually and there will be an up for believe it or not coming this summer that adds NFC style payments from American Express kind of like Apple pay but you gotta have an American Express card and that one is $20 more $200 that's the jawbone up landscape stay tuned for more and full reviews at Cena
