Decision · Decision-making practice
Work through realistic scenarios to clarify goals, compare options and weigh risk and opportunity cost. Feedback looks at how you decided, not at how lucky you got.
Not yet available. Decision is still being planned. This page describes the intended direction, which may change before release.
Four stages: seeing the problem clearly, handling uncertainty, structuring the analysis, and putting it all together in real situations.
Make choices in close-to-real situations, with goals, constraints and incomplete information.
Feedback is based on the goals and risk limits you set, pointing out missed options and costs you didn't count.
Many decisions depend on personal goals and risk tolerance, so not every question is treated as having one best answer.
Decision quality and outcomes are different things: a careful choice can fail through bad luck, and a careless one can work out by chance.
Decision focuses on what you control — clear goals, enough options, and risks you've actually weighed.

| Bad call, good outcome | Good luck |
| Bad call, bad outcome | Deserved loss |
There's no date yet. Once it launches, an App Store link will appear on this page and on All apps.
Forecast trains “what might happen?” — putting probabilities on events and checking the results. Decision trains “what should I do?” — trading off goals, options and risks. The two apps are independent, with no required order.
This is a draft direction. Topics and features may change before release.
