CauseOrCoincidence

CauseOrCoincidence is a focused reasoning app that helps you examine whether two events are truly connected or only happened together by chance.

Work through one scenario at a time with a structured causal stress test. Check timing, mechanism, confounders, pattern strength, and evidence quality before making a final judgment. Challenge your first impression, compare alternative explanations, and save each completed analysis as a reusable Causality Card.

The app is designed for students, curious thinkers, and anyone who wants to practice clearer cause-and-effect reasoning in everyday life. All content is stored locally on your device, with no account, no ads, and no network dependency.
