Worrycast

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.

Walk Window finds your best time to step outside today — and helps you make it a habit that sticks. Every morning it reads the live forecast for your exact location and scores the day hour by hour: temperature, wind, UV, cloud cover, rain, and golden-hour light. Then it gives you one clear window — the calmest, brightest, most pleasant stretch to get outside. WHY IT WORKS A 2010 University College London study found it takes an average of 66 days for a behavior to become automatic. Walk Window is built around that science: a simple daily nudge, a streak that only counts the days conditions were actually good, and milestones that keep you going to day 66 and beyond. FREE, ALWAYS • Your daily walk window, every day • Live conditions: temperature, wind, UV, cloud • A window-open reminder • Basic streak tracking • Walk Mode — a live companion while you're outside (countdown, conditions, encouragement) • Your Walk Window Score — see how you compare to others your age • One-tap mood check-ins after each walk WINDOW+ (subscription) • The full 66-day habit journey with milestones • AI Weekly Insight — personal coaching every Monday, written for your week • Walk with friends — activity feed, weekly leaderboard, reactions & nudges • Mood pattern insights — what conditions actually make you feel best • Morning planning notification • Personal pattern insights • 7-day window forecast • 90-day window history • Indoor alternatives on tough-weather days • Milestone share cards (Day 7, 14, 30, 66) Step out.
