## What is H?

OptionCollapse is an offline decision reduction app that helps users finish a choice instead of keeping options open forever. Start with 3-6 options, eliminate one at a time through structured modes, reach the final pair, and commit to one winner. Each completed run is saved as a read-only Collapse Card with timeline, reasoning, and version history.
