DidntHappen is a fear and overthinking tracker built around one core insight: most things we dread never happen. The app lets you log anxious thoughts in the moment, then tracks real-world outcomes over time so you can compare what you feared against what actually occurred. Over repeated use, it surfaces emotional patterns — which types of worries you carry most, how often they materialize, and where your anxiety tends to cluster. Unlike journaling apps that leave you staring at a blank page, DidntHappen gives you a structured evidence loop: predict, wait, reflect. It's a lightweight tool for anyone who finds themselves catastrophizing or stuck in mental spirals, and wants data rather than platitudes to push back against anxious thinking.
