Estimation & Decision Game PRO

Most people who say they are "90 percent sure" are right only about half the time. GAUGE measures and trains the one skill almost nobody tracks: knowing what you don't know. WHY YOU'LL LIKE IT (all free) - Finally see what you don't know - GAUGE scores how well your confidence matches reality, then trains it. - Find out if you are better calibrated than a frontier AI, right inside the free Lab. - Private by design: on-device only, no account, no sign-up, no tracking, no ads. - No timer, ever - GAUGE measures judgment, not speed. FOUR WAYS TO ANSWER - RANGE: give a 90 percent confidence interval. - CLAIM: judge a statement true or false. - OVER or UNDER: call it above or below. - FERMI: estimate the order of magnitude on a log scale. A TRANSPARENT GAUGE SCORE - A published 0-100 score built on proper Brier scoring. - Coverage, sharpness, and a clear letter grade. - A "how it's scored" screen so nothing is a black box. THE LAB (free) - A calibration curve: your stated confidence versus your real accuracy versus the perfect diagonal. - Overconfident points highlighted so you see exactly where you slip. - Coverage versus your target, plus a by-domain breakdown. - BASELINES that compare you to the roughly 52 percent human average and to a frontier AI. DAILY TEN AND STREAKS - The same ten questions worldwide, once a day. - Build streaks and share a spoiler-free result grid. - An activity heat map, active days, longest streak, and best grade. FREE AI TOUCHES - A short AI micro-insight after each set. - On-demand "why" context on any answer. - Every reveal shows the truth with its source - a micro-lesson each time. PRIVACY - On-device only: no account, no login, no tracking, no ads, no ad identifier. - For the AI touches, only anonymized aggregate statistics are sent to a third-party AI provider - never your identity, device identifiers, or raw per-answer logs. - Export your record as CSV or delete everything anytime. BUILT FOR IPHONE AND IPAD - Universal app with a warm-paper light theme and a dark terminal theme. - Clean monospace aesthetic. For anyone who loves trivia and quizzes but wants something smarter, and for forecasters and fans of decision-making, probability, rationality, cognitive bias, mental models, and self-improvement.
