While the self-tracking devices now are remarkably similar, the goals of the people using them are not.

The team created a service for a segment of self-trackers, “Experimenters” who hack devices and data to satisfy their unique needs. is a platform where self-trackers can create, iterate, and share those experiments. Unlike most self-tracking services, sustains a community of experimenters who build their own unique designs. provides online tools for making those designs, and facilitates sharing of them within the community.
