Apexhone · Think it through
Before the decision that matters,
think it through.
A pocket decision consultant. Apply the same frameworks Bezos, Munger, and Kahneman have used in the field — work through structured questions and sharpen your judgment.
How it works
01
Name the decision
In a few sentences, capture what you are facing — the situation, the constraints, the options.
02
Pick a framework
Choose one decision framework from management, psychology, or finance — and work through its structured questions.
03
Come back and verify
Set a reminder. A few months later, log what actually happened. See your judgment improve, and your blind spots show up.
