About

Calibrate is a beautiful decision journal that scores your judgment over time. Most journals capture how you felt. Calibrate captures what you decided, how sure you were, and whether you were right. HOW IT WORKS 1. Log a decision in under a minute — title, confidence, domain, review date. 2. When the time comes, score the outcome honestly. 3. Watch your hit rate, calibration curve, and domain strengths emerge. BUILT FOR PEOPLE WHO SHIP CHOICES Founders, PMs, operators, investors, and ambitious professionals who make high-stakes calls weekly — and want a private truth dataset, not another diary.
