Next in my gadget backlog series…
I had preordered a Basis B1 Watch a long while ago and promptly forgotten about it, so it was a bit of a surprise to find one sitting on my desk after SXSW (which has turned into this amazing construct of pure marketing – good for business though, I guess).
Since then, I’ve worn it almost every day (about a month-and-a-half). I figured I’d give a report after living with it for a while since Basis is now apparently starting to sell them for real (after being back-ordered for a while).
While I have had reservations on the watch form-factor after getting a MetaWatch and realizing in the intervening decade since I regularly wore one that I now couldn’t stand wearing watches, I’ve mostly re-adjusted, and the data the Basis collects has been worth overcoming the annoyance factor.
There have been a couple reviews (the Verge one isn’t a bad summary), but here’s the basic rundown of what you need to know:
- Price is $199. It comes exquisitely packaged in a die/laser-cut box and overall all the industrial and product design is quite nice (package, device, site/app). The watch is less bulky than the typical smart watch and is pretty inconspicuous. The capacitive touch buttons work well and the display is simple but more than adequate.
- Unlike almost all devices currently on the market (besides the BodyMedia devices), the Basis is a multi-modal sensor device that’s more than just a glorified pedometer. Sensors include:
- Heart-rate via green-laser optical flow-based sensor (I assume using something similar to the TI AFE44xx but sadly, there’s no current support for SpO2 or glucose measurements); An important note is unlike the similarly kitted MIO Alpha, Basis specifically notes that heart rate measurements are not suitable for exercise monitoring
- Skin Temperature (accurate to the tenth of a degree) – mine seems to be about 92-94 degrees fahrenheit when I’m up and a few degrees lower when I’m asleep
- Perspiration specified by μS/cm, so it looks like it’s using galvanic response to calculate? The Basis itself seems to be fairly well waterproofed, and I’ve used it in the shower w/o issues (although usually not, because that’s weird, right?)
- Pedometer and sleep tracking via a 3-axis accelerometer
- Calories burned are derived from BMR via Oxford equations multiplied against a “physical activity level value” that’s presumably derived from the sensor data collected. Note, if you have a better BMR value (ie, I have an RMR estimate from my lean body mass from my Bod Pod measurements, you can presumably use Table 5.2 to reverse calculate what weight to enter to get more accurate estimates)
- Battery life is good for a few days (3-5?) and you need to use a custom charger to recharge. This is a bit of a pain actually, especially if you’re traveling – the charger is a plastic band that hasn’t broken yet, but is just begging to be and will soon enough, I’m sure.
- This charger also syncs data from your device. This is a really important point. While the Basis has Bluetooth (2.1 eww) built-in, it doesn’t work yet and the USB sync is the only way to get your data. Also, there are mobile apps (Android first, then iOS?) on the way, but again, these aren’t available yet. Personally, I wouldn’t recommend this to most end-users until this gets sorted out.
The web interface and the graphs that it gives you is actually quite nice. For me, the actual (almost) dealbreaker wasn’t the lack of wireless/mobile syncing (wireless power and data sync is definitely very high on my list for want-to-haves, personally), but rather that while there’s been the promise of an API/export for quite a while, there’s actually nothing (and no roadmap!) yet.
Paul Miller wrote a great piece on this earlier in the year about this, which I vigorously agree with and I won’t buy or support any self-instrumentation device that doesn’t give me full access to my own fucking biometric data.
Now, if you’ve read the last two paragraphs and are scratching your head on how/why I still have my Basis watch, well, that’s simple: there is an API, it’s just not publicly documented. If you’re an end-user looking for export, yes you are SOL and should send your Basis back and demand a refund if it’s important to you (and it should be!).
Overall I like my Basis although I have an Amiigo on the way that, if it functions as promised, should be better than the Basis in pretty much every single way (sans telling time/wrist display – but that’s not so necessary anyway w/ a proper mobile app). It’s also half the price. For developers and data geeks, the Amiigo also promises to have a full SDK and actual developer support (although I hope they have their data as nicely formatted as the Basis data – it’s totally sweet).
However, the Basis is well designed, and if you’re absolutely buying something today, the Basis is by far and away the best device for those looking for serious self-instrumentation (ie not Fuel Points). The habit system is also on the right track, as well, in terms of general usefulness. However, as outlined, the B1 is also a seriously unfinished product at the moment and anyone expecting basic fitness-tracking functionality (like a mobile app/wireless syncing) will be disappointed. Early adopter caveats definitely apply.
It’s a pretty interesting time for fitness/activity trackers – I think we’ll soon be reaching a point where the sensor-suite will be more than good enough (as mentioned earlier, photometric glucose measurements and SpO2 should be possible w/ the existing sensor packages, and having wireless charging would be the last really nice bit), and the real value will be integrating with other data to create an integrated picture and assisting in behavioral modification/self-improvement. It’s also interesting seing some of the vertical applications as well. The LIT for example looks pretty neat.
UPDATE: Looks like a QS guy also reviewed the Basis and also spotted the JSON feed, and better yet, published some instructions and some code on Github for people.
