Shadow OS is the first mobile app built entirely around decision-making. You type a question about something real you're dealing with and get one clear direction. Not five opinions. Not a pros-and-cons list. One answer you can act on. The framework draws on Carl Jung's concept of synchronicity, applied through 64 hexagrams — one of the oldest systems for understanding change and uncertainty. The app maps the specific situation you described and returns a direction, plus the psychological blind spot most likely to get in your way. It works across five life dimensions: Career, Love, Energy, Conflict, and Timing. Use it for major crossroads or daily decisions. Over time, it surfaces patterns in how you actually decide. Free on iOS and Android. One dimension is free forever. Premium unlocks all five, full reading history, and pattern analytics.
