# Shadow OS

> Shadow OS is a behavioral insight app, grounded in Jungian psychology, that tracks your choices, your state, and what happens next — so you can see what keeps repeating and choose differently. Free on iOS and Android.

Shadow OS pairs a real decision with one symbolic signal — one of 64 inspired by the ancient Book of Changes — records the state the person was in, how they responded, and what they chose, then follows up with look-backs on what actually happened. Weekly and monthly reads connect those records and name what repeats: the same question returning in different forms, choices made under pressure, gaps between intention and action. A signal gives one direction to respond to — move, wait, step back, or reframe — but the choice stays with the user, and the response becomes part of the record. The signal is not the answer; the pattern is. Carl Jung studied the Book of Changes for more than thirty years and called it "a method of exploring the unconscious"; Shadow OS is built in that tradition.
