Tie decisions to the goals they serve.
Attach a decision to an objective, then see which choices actually moved it forward.
Is your judgment getting any better?
Good Decisions records each choice with how sure you were, then scores that confidence against what actually happened.
You remember the calls you got right. You forget how sure you were about the ones you got wrong.
Without a written record, overconfidence never gets corrected. It just gets repeated. Good Decisions keeps the record.
Three moments, one feedback loop.
-
Before you decide
Write the decision, pick a category, set your confidence from 0 to 100. Link it to a goal if it belongs to one. It takes about fifteen seconds.
-
While you wait
Pick a review date. When it arrives, the app reminds you, so nothing depends on your memory of what you were thinking.
-
After the fact
Record what happened and what you learned. Your success rate, calibration and precision update from your own history, overall and by category.
Calibration
Run the numbers on five decisions.
Same math as the app. Change how sure you were, or how it turned out, and watch the scores move.
- Calibration
- average confidence − average outcome. Worked counts as 1, mixed as 0.5, didn't as 0. Within ±10 pts reads as accurate.
- Precision
- the Brier score: average of (confidence − outcome)², shown out of 100.

Questions
What is a Brier score?
It measures how close your confidence was to what happened. For each decision, take the gap between your confidence (from 0 to 1) and the outcome (1, 0.5 or 0), square it, then average across decisions. 0 is perfect. Good Decisions shows it out of 100.
What does "accurate" calibration mean?
Your average confidence sits within 10 points of your actual results. Above that range the app shows you as over-confident, below it as under-confident. The written insight stays tentative: it describes a trend, not a verdict.
When do insights appear?
After five reviewed decisions. Before that, the sample is too small to say anything useful.
Is there a subscription?
No. Good Decisions is a one-time purchase: $8.99 in the US, €9.99 in the eurozone. There are no in-app purchases.
Where is my data stored?
On Amazon Web Services in Ireland, encrypted at rest. The app contains no analytics or tracking SDK. Deleting your account from the app erases your data. Details are in the privacy policy.
Is there an Android or iPad version?
