I was always of the opinion that the health trackers on the market were little more than gimmicks. Most of them were glorified pedometers worn by people who wanted to look like they were fitness conscious people rather than actually using them to stay fit. The introduction of heart rate tracking however presented functionality that wasn’t available before and piqued my interest. However the lack of continuous passive heart rate monitoring meant that they weren’t particularly useful in that regard so I held off until that was available. The Jawbone Up3 was the first to offer that functionality and, whilst it’s still limited to non-active periods, was enough for me to purchase my first fitness tracker. After using it for a month or so I thought I’d report my findings on it as most of the reviews out there focus on it at launch, rather than how it is now.
The device itself is small, lightweight and relatively easy to forget that it’s strapped to your wrist once you get it on. The band adjustment system is a little awkward, requiring you to take it off to adjust it and then put it back on, but once you get it to the right size it’s not much of an issue. The charging mechanism could be done better as it requires you to line up all the contacts perfectly or the band will simply not charge. It’d be far better to have an inductive charging system for it however given the device’s size and weight I’d hazard a guess that that was likely not an option. For the fashion conscious the Up3 seems to go unnoticed by most with only a few people I knew noticing it over the time I’ve had it. Overall as a piece of tech I like it however looks aren’t everything when it comes to fitness trackers.
The spec sheet for the Up3 has a laundry list of sensors in it however you really only get to see the data collected from two of them: the pedometer and the heart rate monitor. Whilst I understand that having all that data would be confusing for most users for someone like me it’d definitely be of interest. This means that, whilst the Up3 might be the most feature packed fitness tracker out there, in terms of actual, usable functionality it’s quite similar to a lot of bands already out there. For many that will make the rather high asking price a hard pill to swallow. There’s been promises of access to more data through the API for some time now but so far they have gone unfulfilled.
What the Up3 really has going for it though is the app which is well designed and highly functional. Setting everything up took about 5 minutes and it instantly began tracking everything. The SmartCoach feature is interesting as it skirts around providing direct health advice but tries to encourage certain, well established healthy behaviours. All the functions work as expected with my favourite being the sleep alarm. Whilst it took a little tweaking to get right (it seemed to just go off at the time I set for the most part initially) once it’s done I definitely felt more awake when it buzzed me. It’s not a panacea to all your sleep woes though but it did give me insight into what behaviours might have been affecting my sleep patterns and what I could do to fix them.
The heart rate tracking seems relatively accurate from a trend point of view. I could definitely tell when I was exercising, sitting down or in a particularly heated meeting where my heart was racing. It’s definitely not 100% accurate as there were numerous spikes, dips and gaps in the readings which often meant that the daily average was not entirely reliable. Again it was more interesting to see the trending over time and linking deviations to certain behaviours. If accuracy is the name of the game however the Up3 is probably not for you as it simply can’t be used for more than averaging.
What’s really missing from the Up3 and it’s associated app is the integration and distillation of all the data it’s able to capture. Many have looked to heart rate monitoring as a way to get more accurate calorie burn rates but the Up3 only uses the pedometer input to do this. The various other sensor inputs could also prove valuable in determining passive calorie burn rate (I, for instance, tend to run “hotter” than most people, something the skin temperature sensor can pick up on) but again their data is unused. On a pure specification level the Up3 is the most advanced tracker out there but that means nothing if that technology isn’t put to good use.
Would I recommend buying one? I’m torn honestly. On the one hand it does do the basic functions very well and the app looks a lot better than anything the competition has put out so far. However you’re paying a lot for technology that you’re simply not going to use, hoping that it will become available sometime in the future. Unless the optical heartrate tracking of other fitness trackers isn’t cutting it for you then it’s hard to recommend the Up3 above them and other, simpler trackers will provide much of the same benefit for a lower price. Overall the Up3 has the potential to be something great, but paying for potential, rather than actual functionality, is something that only early adopters do. That was an easier sell 6 months ago but with only one major update since then I don’t think many are willing to buy something on spec.
