@kchau Very different use cases between the products. Size matters a lot if you want a 24/7 device. If you want smart watch, bigger is likely ok trade-off for size, but means it will come off frequently. More context: https://jawbone.com/blog/jawbone...

@JeremiahLee That's the one big downside I see to this device as well, and the language on their website wasn't that straightforward to figure out how and when it does the HR. But I guess it's not aimed at the athlete trying to track it in real-time.

@JeremiahLee heart rate for UP3 starts this year with resting heart rate as it is the most important place to focus for heart health. Because heart rate changes greatly due to a variety of external factors (caffeine, stress, standing up and moving around, etc) heart rate throughout the day can be very misleading without all that context. Resting heart rate (which technically is the moment right after someone wakes up, before the impacts of the day) gives the best picture of heart health without all the external factors impacting the measure. More details here: https://jawbone.com/blog/up3-wea... Secondly, while it’s tempting to want to see a ton of data on the body all the time, the only way anything is measured in practice is to actually be on the body. Size directly impacts wearability for 24/7 wear. UP3 is about 30% of the width of Charge HR (volume I’m sure is much smaller) and about a 50% reduction in volume from UP24. For active HR during a workout, it is likely to be worn much like a Tom Tom or Mio, but those are very different use cases. More details here: https://jawbone.com/blog/jawbone...

@gregoiregilbert Oh, tell me more. I was the user of the first gen UP. Haven't touched UP in years now. Quite excited about UP3, really hope it can deliver on its promises.

@gregoiregilbert Guess you got unlucky (or I got lucky), because my UP24 works great. Don't use it a ton, but never had any problems with the hardware or software.

@marckohlbrugge hey Marc! Maybe, but considering Jawbone's forum I'm not the only one. I use it a lot, wear it all the time (well when I have a working band).

@gregoiregilbert Can you get it replaced? Mine broke after less than 2 months of use and I haven't figured out what to do. The sad thing is that I don't really miss it that much. Sleep and step tracking was cool, but if it's going to break every 2-3 months, it's not worth the hassle...

@gregoiregilbert I've found the support was always pretty good in my experience, but I've had to replace 3 original UPs and 1 UP24 so far, so yeah I'm not impressed with the hardware.

@michael_xander It's nice... but not completely necessary. Most of my winter workout is on a stationary cross trainer, or other machine; so I'm not going anywhere cool anyway.

@michael_xander There is a big challenge with that. The act of putting in 24/7 GPS tracking means it's something you won't wear 24/7 because it grows a lot. The reality is you can get this by using your phone for the GPS tracking since that is on you for all the major movements. The movements within places where phone may be on charger or off body, is less likely to have much delta from a GPS perspective. See link right above for URL to more context.

@andyfortson Same.

@brian_lovin This is one of the things I love about Buffer - their dedication to actually looking after the wellbeing of their team on the understanding that it'll make them more productive employees.

@riaface Absolutely! Great to see companies valuing the creativity and productivity gains seen through a healthy and active office culture.

@brian_lovin also really excited about it tracking REM sleep!

@brian_lovin Agreed on water resistance. I'm so confused at the serious lack of water-resistant trackers. As soon as something comes off my wrist to shower, it might as well be put away in the back of a remote warehouse.

@maxisnow @brian_lovin Agreed on the water resistance. It's one of the things I most appreciate about my Pebble (but it doesn't replace activity trackers yet).

@davidkmckinney Wearables are challenging because the body goes through a lot in the course of 24/7 wear. UP Move & UP3 benefit from all these years of learning and quality & durability has been built in from the early stage of the designs.

@travisbogard I can't even imagine how hard it must be to design and build hardware for daily use on your body. It's the full triple threat. Love seeing JB pushing like this.

@davidkmckinney Good point. Jawbone's been known for unreliable hardware, but I've had a Misfit Shine stop working and of course the Fitbit Force rash debacle - so it's not just Jawbone that's struggling to get the hardware right.

@nikkielizdemere Problem I have with the UP24 is that it's too thick to comfortably wear when using a keyboard. The consequence of this is that I hardly wear the device which defeats the purpose. Unfortunately it seems the UP3 still has a pretty thick wristband.

@marckohlbrugge @nikkielizdemere I have the same issue. Although I've found if I wear it upside down (with the connector/button on top of my wrist) I can more easily rest my hand on my keyboard... still not comfortable, but better. The UP3 looks like it's clasp is much thiner though. I'd assume it feels more like wearing a watch, which I do everyday while using my keyboard.

@cyborgnation @marckohlbrugge @nikkielizdemere I'm curious to know why/when you'd want an activity tracker bracelet over an M7-tracking phone app? Both give you a good sense of how active you've been (but I hate having something on my wrist while typing + lack of water resistance, so I stick to my phone for now).

@tymrtn @marckohlbrugge @nikkielizdemere I don't always have my phone on me. I typically dock it at my desk and that's where it stays all day and I hate the idea of having my phone on my bed all night to try and track my sleep. Outside of the annoyance while typing on my laptop, the band takes the function of several M7 apps and turns them into these simple, almost passive functions. Going to sleep? Cool press this button once. Going for a run? Press the button then hold it again. Want to take a quick power nap? Press it twice then hold. Not to mention that if I forget to track my sleep with an M7 app that's just a night lost. With the UP24 if I forget to turn on sleep mode, it's still tracking that motion data and I can log the sleep the next day and still get the same data. I guess overall, for me, it's just easier to build habits around this dedicated device than it is to use an app on my phone.

@cyborgnation @marckohlbrugge @nikkielizdemere Thanks Joe. Good response (appreciate the details). So what do you do with all of this data then? And may I ask how long you've been using your tracker? Also, what activity are you doing while your phone is at your desk?

@digitalbase I used the original Basis and loved it but it had several issues: serious sync problems - ran out of memory often, had a very complicated charging cable, ran out of charge quickly, but the biggest problem was the strap which kept breaking off from the base unit and I had to buy a second one just because of that. Hope they fixed all those issues in Peak. After the Basis, I found Misfit Shine - no charging for 3 full months which was a big relief especially when you travel and don't have to carry an extra cable. But a couple of months of use and the Shine started giving inaccurate metrics and I stopped using that. I've tried other ones too like the Lumo Back (which was better than the successor Lumo Lift which I used for just one day). Of all the wearables I've tried Fitbit gets the prize for being the worst - both inaccurate and terrible product design and usability. Right now I'm using a Garmin 620 Forerunner to train. Design and usability are terrible but it has a couple of things like GPS, VOX, Recovery time, and Cadence that are valuable for runners. It is not really meant for 24x7 wear though.

@digitalbase I hadn't heard about the habit-building features of the Peak. They sound really cool. Unfortunately Basis is out for me because they've been promising an API for years and still haven't released one. I won't use a device that doesn't let me get my data into Exist, and I don't think any personal data company should be supported to hold that data hostage.

@PGopalan Actually, Fitbit trackers have repeatedly been determined to be the most accurate activity trackers on the market by medical researchers. Here's one recent study: http://www.news.iastate.edu/news...

@JeremiahLee Thanks. The study you pointed above actually says "BodyMedia FIT was the top performer with a 9.3 percent error rating". Maybe I got a bad Fitbit two times in a row - it often counted my steps when I was driving a car!

@JeremiahLee I love my FitBit - I still rock an old school one that's lasted for a couple of years. I also have their Aria scale, which is great for combining the data. However, their unwillingness to data dump into Apple Health is now having me look elsewhere.

@basprass I can see it just fine. Browsing from Eindhoven on Safari. (the browser, not an expedition to observe animals in their natural habitat).

@tymrtn Phone misses about 20% of steps because it isn't always on the body. And of course sleep tracking is one of the most interesting things that being on the body makes easy.

@tymrtn Most phone trackers require that you walk for 30 secs+ before they pick up your steps, so even if you do put your phone in your pocket all the time, you'll miss a lot of your steps around the house because you don't move for long enough periods. Having said that, Jawbone overestimates my steps way more than Fitbit or the Misfit Shine, so I can easily get 2,500-3,000 steps in a day with my UP24 without leaving my house at all (and it's a tiny bedsit).

@tymrtn While I do love my iPhone 6 Plus, I can't see myself carrying that everywhere I go like a newborn. It's just too much.

@cx42net You do put it into sleep mode so you get things like "Time to Fall asleep", but if you fail to it will recognize when you went to sleep and allow you to confirm.

@travisbogard so I aren't forced to indicate it when you go to sleep ? It won't just be as accurate as if you did? Interesting!

@cx42net @travisbogard I forget to put mine in sleep mode all the time. It usually asks me if I was sleeping in the morning, but even if it doesn't I can input the time frame I think I was asleep for and it will still show me my light/deep/awake sleep for that time. Really cool.

@travisbogard @cx42net Time to fall asleep is a nice feature actually. Probably a good correlate to overall stress levels.

@cyborgnation @cx42net Yep, that's right. It figures it out, suggests it and you still get the sleep detail.
