150 of the Best Self-Quantification Tools (Apps, Sites and Trackers)

“You can’t change what you don’t measure.”

If anything encapsulates the potential for self-tracking to transform our health, then it’s that statement.

The so-called life-logging revolution is already well underway after technological advancements, ‘big data’ and key influencers like co-founder of the Quantified Self Gary Wolf have created opportunities and raised awareness. The revolution is slowly shifting us away from the old paradigm of self testing ‘after-the-event’ of sickness/symptoms, to a more proactive approach of gathering data when we are feeling ‘normal’, and using it to optimize health and wellbeing. 

We can use tracking for anything that we want to see improvements in. Chances are, you have already tried self-tracking. Ever kept a food diary? Used a calorie or fitness tracker? This is quantification.

And there are no drawbacks to this kind of physical self-awareness (although we need to know how to get the most from tracking tools to generate actionable insights. We also want to avoid self-tracking becoming a source of stress!)

Below is a round up of some apps, sites, wearables and other tools that you can use to track your health. (The list is focused purely on quantifying – data gathering – tools. At some point there will be a Part 2 looking at techniques and tools we can use to optimize health. Stay up to date by subscribing to our email list).
