Calibrate: Decision Journal

Your gut has a track record — you just don’t have the data. Log decisions, score outcomes, and see where you’re actually calibrated.

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.
