A decision journal for people who want to reason better. Track your confidence, learn from outcomes, and see if your judgment actually improves.
Good Decisions is not a diary. It's an analysis tool for people who want to reason better.
Most people can't tell if their judgment is improving. There's no data, no baseline, no feedback loop. Good Decisions closes that loop: capture a decision in under 15 seconds (title, category, confidence level) and get reminded when it's time to review, then log what actually happened.
Over time, two things surface that no other iOS app tracks:
CALIBRATION
Your Brier score compares the confidence you declared against your actual outcome rate. Not "how many decisions went well", whether your confidence itself is trustworthy. See if you're overconfident, underconfident, or well-calibrated, overall and by category.
GOAL LINKING
Attach any decision to a personal objective and watch how each individual choice moves that goal forward. Decisions and goals, usually tracked in separate apps or not tracked at all, live in one place.
HOW IT WORKS
1. Before deciding: log the choice and your confidence level. Link it to a goal if it's part of something bigger.
2. While you wait: a reminder fires automatically on the review date you set. No manual follow-up.
3. After the fact: compare prediction to reality, log the lesson, watch your calibration shift.
No diagnosis, no motivational fluff, no vanity metrics. Just your own decisions, reflected back at you with real numbers.
