Write down predictions, check them when they're due, and learn from the results. Free, private, no account needed. How good is your judgment, really? FoMind helps you turn gut feelings into reliable judgment. • Make a prediction: ask a yes/no question, define how it will be resolved, write your reasoning, then commit to a probability from 1% to 99%. • Check it when it's due: get a reminder on the resolve date, judge the outcome against your own criteria, and attach links or screenshots as evidence. • Review and improve: separate luck from skill, note which reasons held up, and save the lessons you want to remember. • See how accurate you are: Brier score, monthly trend and a calibration curve show whether you're overconfident or too cautious. • 29 short lessons: conditional probability, Bayesian reasoning, base rates, causality, Fermi estimation and cognitive biases. Every lesson has a quiz, and 14 include interactive demos. • Home Screen widget, due-date reminders, and export to JSON and CSV. Your data stays on your device and in your own iCloud. No account, no ads, no data collection. Available in English and Simplified Chinese.
