Most wellness “stacks” are one‑size‑fits‑all. You end up with more subscriptions, more noise, and no clarity on what changes what. Stack Recipes give you a minimal, time‑boxed combo of devices, signals, and habits aimed at a specific mystery, so you learn quickly and avoid overwhelm.

Productivity apps tell you what to do. They don't care if you have the energy to do it. Context tracks your focus, energy, and habits alongside your sleep, stress, and health - so you can build systems that actually work with your body, not against it.

Yearly checkups and one‑off labs tell you what a number was, not why it moved or whether your changes worked. Turn scattered data into 3–12 month health projects with clear goals, signals, and reviews.

A Personal Data OS unifies signals and moments into one private, portable timeline you control.
