The Quantified Self is an international community of users and makers of self-tracking tools, who share an interest in "self-knowledge through numbers." This includes people who are doing personal projects as well as developers, hackers, and entrepreneurs. There are more than 100 Quantified Self groups in more than 30 countries. QS Labs, LLC, is a California-based social enterprise that supports the Quantified Self movement worldwide.
The QS mission is to inspire meaningful discoveries about ourselves and our communities, grounded in accurate observation and enlivened by conviviality. Among other activities to support the community, QS Labs produces two annual Quantified Self conferences: the QS Global Conference (Bay Area), and the QS Europe conference (Amsterdam).
