Harald KlinkeHow accurate is your Apple Watch?A new meta-analysis from the University of Mississippi reviewed 56 studies comparing Apple Watch data to clinical tools. Result: ✔️ Accurate for heart rate (4.4% error) ✔️ Fair for step counts (8.2% error) ⚠️ Inaccurate for calories burned (28% error)Wearables are useful for habits and motivation—but not diagnostic tools.

Karsten Schmidt"Eventually, I stopped responding to my body. I was responding instead to a dashboard." — <a href="https://mastodon.social/@Daojoan" class="u-url mention" rel="nofollow noopener" target="_blank">@Daojoan</a> This is a great point and very much translates to so many other parts of life/work where people stop listening to their "body" (or to their org/product/offering), outsourcing/numbing/dumbing down their decision making based on dashboards of collected metrics and then changing their behaviors on auto-pilot to improve said metrics — without ever asking themselves if the data collected actually represents answers to the right (or even important) questions...Metrics always invite comparison & competition — on a global scale — often without considering our own subjective contexts/needs/limits/aims...Does the number of copilot prompts per day on a CTO dashboard indicate a highly productive developer or does a big fat zero merely show a different approach to problem solving?Does the lack of constant updates to a FLOSS project mean it's become neglected/unusable or does it simply indicate it reached a level of stability?Likewise, does my product/app need constant UI changes/updates to "streamline" user experience (often without even consulting users) based on some "goal" metrics?Am I seen as an unproductive FLOSS developer if my public commit log doesn't show daily updates? Do gaps indicate laziness, illness, deep thinking or work on other projects? Like gaps in a CV, will these gaps of activity data hinder future employment chances or would I even want to work with orgs who select on this criteria?Is a hike only good/better because it exceeds X kilometers or Y elevation meters? How does one measure the stunning views or the quality of the company which shared that experience?<a href="https://www.joanwestenberg.com/why-i-gave-up-my-smartwatch/" rel="nofollow noopener" translate="no" target="_blank">https://www.joanwestenberg.com/why-i-gave-up-my-smartwatch/</a><a href="https://mastodon.thi.ng/tags/Blog" class="mention hashtag" rel="nofollow noopener" target="_blank">#Blog</a> <a href="https://mastodon.thi.ng/tags/Dashboard" class="mention hashtag" rel="nofollow noopener" target="_blank">#Dashboard</a> <a href="https://mastodon.thi.ng/tags/QuantifiedSelf" class="mention hashtag" rel="nofollow noopener" target="_blank">#QuantifiedSelf</a> <a href="https://mastodon.thi.ng/tags/DataViz" class="mention hashtag" rel="nofollow noopener" target="_blank">#DataViz</a> <a href="https://mastodon.thi.ng/tags/Behavior" class="mention hashtag" rel="nofollow noopener" target="_blank">#Behavior</a> <a href="https://mastodon.thi.ng/tags/DecisionMaking" class="mention hashtag" rel="nofollow noopener" target="_blank">#DecisionMaking</a>

Dave MackeyYou know what would be really cool? A <a href="https://hachyderm.io/tags/quantifiedself" class="mention hashtag" rel="nofollow noopener" target="_blank">#quantifiedself</a> person influence monitor. Say I have a <a href="https://hachyderm.io/tags/Fitbit" class="mention hashtag" rel="nofollow noopener" target="_blank">#Fitbit</a> and Joe has a Fitbit, we could have them detect when we are in proximity (if both people agreed) and then it would let us know over time how being around the other person influenced us - e.g. did heart rate variability increase or decrease (do they relax us or cause stress), did we burn more calories (maybe we usually go on hikes together), did we sleep better that night, and so on.There are definitely people in my life who I'm pretty sure have significant effects on me in both directions, it'd be awesome to quantify them.It would also be cool if one could do this without data sharing - e.g. maybe one presses a button on ones device to indicate one has entered x's presence and again when one has exited...Honestly, I'd totally forget to do this...so something passive would be better - e.g. when you want to start tracking the next time you are around someone you press a button and it scans for electronic signatures and identifies Bluetooth etc. uniquely so that when you are around then it auto knows and can record...The latter raises issues of <a href="https://hachyderm.io/tags/consent" class="mention hashtag" rel="nofollow noopener" target="_blank">#consent</a> and <a href="https://hachyderm.io/tags/privacy" class="mention hashtag" rel="nofollow noopener" target="_blank">#privacy</a>...I'm not sure how/if one could do this in an ethical manner...but I'd like to have it 😂

Bastian Greshake TzovarasAs part of moving away from iOS, I've also replaced my Apple Watch with a Garmin device. Which means I'll have to figure out a way to get some of those data out to display it in my website footer!Does anyone have a recommendation/existing solution for how to export small chunks of that data in regular intervals to an HTTP endpoint? Or will I have to learn how to use the Garmin API after all? 🙈 <a href="https://scholar.social/tags/wearables" class="mention hashtag" rel="nofollow noopener" target="_blank">#wearables</a> <a href="https://scholar.social/tags/fitness" class="mention hashtag" rel="nofollow noopener" target="_blank">#fitness</a> <a href="https://scholar.social/tags/quantifiedself" class="mention hashtag" rel="nofollow noopener" target="_blank">#quantifiedself</a> <a href="https://scholar.social/tags/personalscience" class="mention hashtag" rel="nofollow noopener" target="_blank">#personalscience</a>

richardOf Suunto, Garmin and AppleReading Time: 3 minutesFor years I wore no watch, and then I took up scuba diving, and then I wanted to wear a watch when climbing, and then it escalated from there. Now I have Garmin, Suunto Apple, Casio, Xiaomi and other watches. It's easy to justify wearing the Apple watch because it's a smart watch so it has a niche. It's harder to justify the Garmin, Suunto, Xiaomi and Casio watches because they overlap each other.I have written about this topic but I will write about it again, because people are amused, and confused, by why someone would wear two or three watches. I am frustrated that I feel the need to wear two or three watches. I'd like to be happy wearing just one.GarminRecently with Garmin Connect+ I noticed that between the time when I finish a long hike and the moment the hike is available on Garmin Connect can be quite long. It takes several hours now. I think that by adding AI Garmin have increased server load, thus slowing down the ingestion process.Despite the slowness the Garmin Instinct 2, as a device is great. It has great battery life. It's accurate, tracks HRV and gives me info about whether I am pushing too hard and more, for about 150 CHF. Contrast this to the Epix for 600 CHF or more.SuuntoBy now I have been wearing Suunto watches for decades, from the Suunto D9 for scuba diving to the Suunto Vector for climbing, to the Suunto Ambit 2, 3, Spartan Wrist HR baro and finally Suunto Peak 5. I also liked Sportstracker since the Nokia N95 8GB to when it was bought by Suunto and integrated into Movescount before being rebranded as the Suunto App.Compared to other Suunto I have owned the Peak 5 is mediocre. Battery life is a few days, rather than a few weeks. Accuracy can vary and it's a little slow to detect satellites. Having said this I like the metrics that it gives, and I like that it creates a weekly or monthly map of the activities I have done.Within a few seconds activities are synced and visible in the mobile app, with information about progress and more.Apple Watch SEThe Apple Watch SE is the cheapest Apple watch. As a result battery life is short. If I do a six or seven hour hike it will almost always die near the end of a hike. This means that I will get most, but not all of the hike.The SE is great for short walks, and bike rides. It also provides quite a bit of data despite the low, by Apple standards, price point. PricesThe Garmin Instinct 2 was 147 CHF and the Suunto 5 Peak was 151 CHF. Meanwhile the Apple Watch SE was 299 CHF.The AbsurdityIt's absurd that Garmin has its own little world, with fitness tracking, health checkups, awards and more. It's absurd that Apple has the same gamification. Both want us to be stuck in their little worlds. I find it tremendously frustrating that we have to choose between either or, and that they do not play nicely together.Suunto and SportstrackerThat's where Suunto and Apple, via Sportstracker, play nicely. The Suunto App, and the Sportstracker app are the same app, except that Suunto takes data from Suunto devices, and the Sportracker app, on iOS takes data from Apple Watch devices.And FinallyRecently, as I go on four to seven hour hikes I find that the Apple watch battery keeps dying while I'm walking. It is for this reason that I have played with the idea of replacing the Apple watch with the Suunto watch. Having said this, despite better battery life, the Apple Watch gives far more data than the peak five. It measures form, recovery, estimates watts when running and cycling and more. It also has an entire app ecosystem.If you're hesitating between the Peak 5 and the Garmin Instinct 2 go for the Garmin Instinct 2. If you're tempted by the Apple Watch SE then keep in mind that this is a smart watch first, and an adventure watch second. If you walk for an hour to catch a train, and go for a five hour hike then the battery will probably die. It does last better, if you just wear it as a step counter that happens to measure heart rate.In summary, if the Apple watch battery lasted better I wouldn't wear two, or even three watches, every so often.<a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://www.main-vision.com/richard/blog/tag/apple/" target="_blank">#Apple</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://www.main-vision.com/richard/blog/tag/data/" target="_blank">#data</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://www.main-vision.com/richard/blog/tag/fitness/" target="_blank">#fitness</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://www.main-vision.com/richard/blog/tag/garmin/" target="_blank">#Garmin</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://www.main-vision.com/richard/blog/tag/quantified-self/" target="_blank">#quantifiedSelf</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://www.main-vision.com/richard/blog/tag/suunto/" target="_blank">#suunto</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://www.main-vision.com/richard/blog/tag/trapped/" target="_blank">#trapped</a>

Max LeibmanContinuous glucose monitoring is kind of a miracle, but one of the shortcomings of the one I use (FreeStyle Libre) that I find irksome: a precipitous decline in blood sugar will cause the sensor to go offline. It’s always, always a sharp decline, but never for a spike. Glucose shooting up because you’ve been irresponsible? Nope, we saw that. It’s in your permanent record. Glucose coming down fast because you’re doing something good for yourself? We’re gonna take a break. You don’t need that accomplishment in your graph, do you? <a href="https://beige.party/tags/diabetes" class="mention hashtag" rel="nofollow noopener" target="_blank">#diabetes</a> <a href="https://beige.party/tags/motivation" class="mention hashtag" rel="nofollow noopener" target="_blank">#motivation</a> <a href="https://beige.party/tags/QuantifiedSelf" class="mention hashtag" rel="nofollow noopener" target="_blank">#QuantifiedSelf</a>

HabrТеоретические и практические рассуждения об оцифровке отдельных аспектов личностиВ контексте ИИ в статье понимается использование комплекса механизмов на основе LLM + reasoning + agents + RAG + ML. В контексте статьи оцифровка личности или самодигитализация – это практика всеобъемлющей записи и оцифровки различных аспектов жизни человека. Идея статьи заключается в обзоре теоретических и практических аспектов создания «единого цифрового архива всего опыта индивида» – то есть фиксировании практически полного набора мыслей, переживаний и действий человека в цифровой форме. Для этого используются разнообразные средства: от носимых сенсоров и приложений до "цифровых дневников". Концептуально самодигитализация близка к движениям Quantified Self и лайфлоггинга , цель которых – « самопознание через сбор данных о себе с помощью технологий ». В итоге получается постоянный поток персональных данных – своеобразная «чёрная коробка» жизни человека, превращающая его повседневный опыт в данные, пригодные для хранения, анализа и воспроизведения.<a href="https://habr.com/ru/articles/886026/" rel="nofollow noopener" translate="no" target="_blank">https://habr.com/ru/articles/886026/</a><a href="https://zhub.link/tags/SelfDigitization" class="mention hashtag" rel="nofollow noopener" target="_blank">#SelfDigitization</a> <a href="https://zhub.link/tags/QuantifiedSelf" class="mention hashtag" rel="nofollow noopener" target="_blank">#QuantifiedSelf</a> <a href="https://zhub.link/tags/AIPersonalization" class="mention hashtag" rel="nofollow noopener" target="_blank">#AIPersonalization</a> <a href="https://zhub.link/tags/LifeTracking" class="mention hashtag" rel="nofollow noopener" target="_blank">#LifeTracking</a> <a href="https://zhub.link/tags/DataDrivenGrowth" class="mention hashtag" rel="nofollow noopener" target="_blank">#DataDrivenGrowth</a> <a href="https://zhub.link/tags/DigitalTwin" class="mention hashtag" rel="nofollow noopener" target="_blank">#DigitalTwin</a> <a href="https://zhub.link/tags/PersonalAnalytics" class="mention hashtag" rel="nofollow noopener" target="_blank">#PersonalAnalytics</a> <a href="https://zhub.link/tags/LifeOptimization" class="mention hashtag" rel="nofollow noopener" target="_blank">#LifeOptimization</a> <a href="https://zhub.link/tags/CognitiveTech" class="mention hashtag" rel="nofollow noopener" target="_blank">#CognitiveTech</a> <a href="https://zhub.link/tags/BiohackingData" class="mention hashtag" rel="nofollow noopener" target="_blank">#BiohackingData</a>
