Most of your worries never come true. Worrycast helps you prove it. Every worry is a forecast: "the meeting will go badly", "they're mad at me", "I won't cope tomorrow." Worrycast takes your forecast seriously - and then checks it against reality. MAKE A PREDICTION When anxiety strikes, write down exactly what you think will happen. Be specific - "My presentation will go terribly" or "Nobody will talk to me at the party." CHECK BACK LATER Pick when you'll know: tonight, tomorrow, next week. Worrycast reminds you at exactly that moment. RECORD WHAT ACTUALLY HAPPENED Did your fear come true? Usually it didn't. Across all predictions tracked in Worrycast so far, 73% never happened. WATCH YOUR OWN PATTERN Your personal accuracy stats build undeniable proof that your mind overestimates danger. That evidence is what quiets the next worry, calms overthinking, and interrupts rumination before it spirals. Worrycast is built on behavioral experiments from Cognitive Behavioral Therapy (CBT) - one of the most effective techniques for anxiety, worry and intrusive thoughts. Instead of fighting your thoughts, you test them. The evidence does the rest. No account needed. Your data stays private.
