I ordered a Withings pulse as I already had both the Withings blood pressure and scales and despite being a user of the Jawbone Up I wasn't completely satisfied with that device. I have been using the Jawbone UP
since it was released and found it good a motivating me to move about rather than sit and work. I have found having all my lifestyle data to hand helps when dealing with the medical profession; and into shaming me into doing more with my time. My biggest criticisms of the Up were its lack of Bluetooth - relying on the headphone jack to connect to my phone; and that it couldn't do pulse readings. The Withing's pulse ticked both of those boxes. Once it was charged up using a standard Micro USB cable (the Jawbone uses a proprietary 3.5mm charger) As I am expecting of Withings product setup was an absolute breeze; connect the bluetooth using the phone menu, run the app and (After a firmware update to the pulse) I was away. The Pulse is very small; about half the size of a pack of matches if you can remember them. The iPhone Withings App is very polished outstanding (and designed by them to encourage you to track more of your life through their products - which i guess worked on me.) Besides having the data on your phone its also accessible via the Withings website.
The Up comes in the form of a plastic bracelet which is pretty visible as you move around (especially as mine is in Blue - grab a handle on the Tube and it shouts out from my exposed wrist to those who care to look - possibly breaking the rule about the only jewellery men should wear being glasses, wristwatch and dog tags); the pulse is a rounded lozenge that goes into a belt clip or a separate wrist cuff for nighttime use. With the Up you put on and leave it for a week (or until you go swimming) sleep; suit shower its happy all the Time. The lozenge shape of the Pulse results in a belt clip for daytime use; a wristwatch like sleeve for nighttime use; and as its not waterproof a shelf when you take a shower. This constantly changing holder is a chore; I am not enamoured by the belt clip either which didn't feel 100% secure It may be more discrete than the UP but I am less concerned with losing the up. I also found myself taking it off when i got to work so it didn't get caught on chairs during the day which meant it did my commute but unless I remembered to put it on not whilst i was moving around the office. The nighttime sleeve works fine; its just with the Up its on your wrist and you only take it off to charge - and as it doesn't have a screen or bluetooth you charge it a lot less. My Pulse managed about 3 days on its first charge and 3 again on the second - the Up lasts all week comfortably. I am happy to sacrifice battery life for the screen though - it makes it much more clear where you are and the Pulse is much easier to use than the up as a Result.
The Pulse reader itself; is activated using the menu button and selecting the heart from the touchscreen; when it comes to taking your pulse its a bit hit and miss - and doesn't give you the chance to try again or delete a dodgy reading. So my pulse history is mostly 60's and 70's with the odd 150-180. Whenever these readings happened taking my pulse instantly again recorded what was expected. The pulse reading when giving an answer I as happy with agreed closely with the reading taken from the Blood pressure cuff. The movement tracking was in 5% of the Up; and what little sleep I get resulted in similar sleep pattern readings.
My review of the Up was titled Shakes you up; and that is for me where the Pulse is let down. The Up has a motor that makes it vibrate - this means it can act as an alarm clock in sleep or napping modes. Thought the biggest use of the motor for me was telling me I had been sitting still for too long and I should get up and do something - that little motivation works wonders. The pulse is passive; it tells you what you have done and the app tries to get you to do more; the Up shakes you to get up and do something. I bought the Pulse as I wanted something to replace the up; what I have ended Up with is two wristbands neither of which I am 100% happy with. The Pulse is much more user friendly; and I haven't lost it via the belt clip yet; but constantly shuffling between holders is a Pain. The UP though takes more effort to sync up to your phone; can't take your pulse and although the Jawbone app can sync data from other Withing's devices it doesn't have the all round health features of the Withings. I'm torn between the two they both track and show back the data accurately in user friendly ways; but for now the Up has it simply for shaking tell me to get up and do something.
