measured me blog quantified self product reviews and experimentsAs you may have already noticed, I have not been posting much lately. No worries, Measured Me project is still live and kicking; I continue updating my Lifestream dashboard every week, and have been testing some new awesome Quantified Self tools like Nick Felton’s Reporter app and Zeo’s offspring sleep tracking device Beddit. I only wish I had time to sit down and put my thoughts and observations together. I am currently working on some large projects at my full-time job, and this takes most of my time. So at this point, I decided to take a hiatus from blogging for a couple of months. For the same reason, I won’t be able to attend this year’s awesome Quantified Self conference in Amsterdam, and will stick to only local QS meetups.

Still, please feel free to drop me a message or comment on this blog, and I will try to respond in due course. Happy tracking!

Tinke – My First Impressions

tinke review by measured meI recently purchased Tinké sensor, and have been using it for the past couple of weeks. The full review will be coming later (I still need to accumulate enough data), but so far I LOVE IT! My first impression is: it is extremely easy to use! Just plug the sensor into your mobile phone, launch the app and tap on the screen. It also provides a lot of interesting metrics, which I hope to use in my self-tracking experiments and projects. Here is a quick breakdown.

My Case Against Longevity Research: Some Thoughts

longevityI have noticed that a lot of Quantified Self folks and biohackers are interested in longevity research. Personally, I never could understand their fascination with extended life. While I am not completely AGAINST the studies in this area, I regard the whole concept more cautiously and with much less enthusiasm. Lately I have been jotting down some thoughts on this topic, and would like to share them in today’s post. Please note that these are just half-baked thoughts, and I am yet to write a full post (hopefully, sometime in the future).

My Notes from the 2013 Quantified Self Conference in San Francisco

quantified self conference san franciscoAs you may already know, a couple of weeks ago I attended the 2013 Quantified Self Conference in San Francisco. This was my very first QS conference, and even after two weeks I still feel overwhelmed. The program was full of amazing and inspiring presentations, engaging and thought-provoking “break out” sessions, and demo sessions for cutting edge QS products and services. I also got to meet a lot of interesting like-minded people, including some “movers and shakers” of the QS space and A LOT of readers of Measured Me blog. In today’s post, I will would like to offer a recap of some of the things that I found especially interesting.

My Talk at the 2013 Quantified Self Conference

my QS conference presentation picAs promised, posting today the slides of my “100 Days of Summer” talk that I presented at the 2013 Quantified Self conference in San Francisco last Thursday (October 10). In this presentation, I shared most important and interesting results of the first phase of Measured Me project.

Talking 20: After Lots of Talking, Not So Much To Tell

talking 20 blood test reviewTalking 20 is a young biotechnology start-up in California that aims at making low-cost, at home blood tests that could be used to track twenty essential amino acids (hence the name). In October 2012, I responded to their call for support on Twitter and purchased “T20 Starter Pack” home kit for ten dollars. I paid 12 dollars (2 dollars to cover shipping), and a couple of weeks later received the kit, which I mailed back to them in December. After waiting patiently for ten months, I can finally share with you what I learned from my blood test. Drumroll, please…

Three Temporal Patterns That May Affect Your Quantified Self Insights

temporal trends in quantified self dataIn this post, I will discuss three invisible temporal patterns that are likely to be present in your self-tracking data and which, if ignored during analysis, may lead to erroneous conclusions and interpretations. I am talking about trends, social rhythms and intra-day variability.

Interview with Dr. Rob Miller, Developer of rTracker App

rtracker app interview with developer Measured Me blogA while ago I blogged about my search for the best self-tracking tools (link to part 1; , link to part 2), and one of the apps that came up in the final was rTracker. I have been using it since then, and have become a huge fan. rTracker now is a central tool in my Measured Me experiment – an attempt to capture and express my everyday life numerically. I usually try to stay as neutral and unbiased as possible in my reviews, but in case of rTracker, my engagement has evolved from being an enthusiastic user to becoming a “brand advocate.” I thought it would be great to finally “meet” a genius behind such an amazing app, so a couple of weeks ago I contacted Dr. Robert Miller, founder of Realidata Ltd. and developer of rTracker. He kindly agreed to answer a couple of questions for Measured Me blog.

Self-Quantification vs Self-Tracking

self quantification vs self trackingIn this post I would like to briefly discuss differences between self-quantification and self-tracking. These two terms are sometimes confused with one another because they both concern with measurement. To me, however, they are conceptually different, and seeing them used interchangeably kind of bothers me.

Some Thoughts on Building The Perfect Tool for Tracking Diet (Part 1)

perfect gadget for tracking dietA couple of weeks ago, I shared some lessons that I learned while tracking my diet for over six months. One of the conclusions was that tracking diet is one of the most cumbersome aspects of self-quantification/self-experimentation, mainly due to the lack of passive measurement tools and often overwhelming amount of nutritional information to collect and deal with. That naturally let me to the question: how can we make the diet tracking process easier? What would the perfect tool for tracking diet look like? The longer I am pondering this problem, the more I realize that we are talking not about a single stand-alone gadget or app, but rather a small ecosystem that includes digital scale, mobile phone and content. Let me now elaborate.
