DecisionLoop is a decision journal. Write down a decision, how sure you are, and what you expect to happen. On the review date, come back and record how it actually turned out.
Over time you see something most people never measure: how good your judgment really is, and where your confidence is off.
HOW IT WORKS
• Log a decision in under a minute: what you decided, the category, how confident you are (0–100%), what you expect, and when to review it.
• Get a reminder on the review date.
• Record the outcome: better than expected, as expected, or worse, and whether you would decide the same way again.
• See your accuracy and its 30-day trend. With Pro, see it by category, and the gap between how sure you felt and how often you were right.
FOR BIGGER DECISIONS
• Compare up to three options, scored on expected value, risk control, reversibility and value alignment.
• A bias checklist before you commit: confirmation bias, sunk cost, second-order effects.
• Mark the stakes, the time horizon, and whether the decision is reversible.
BUILT TO KEEP YOU HONEST
• Your record locks 24 hours after you log a decision, so hindsight can't rewrite how sure you were. Until then, fix anything.
• Not sure yet how it turned out? Reschedule the review instead of guessing.
• A weekly review session for every decision that is due.
• A weekly digest of what you decided and how it went.
• Search every decision, expectation and note.
• Backup and transfer of your data, free.
FREE AND PRO

PRIVACY
Your decisions and notes are stored on your phone. There is no account to create. Anonymous usage statistics help improve the app; they never include what you write.
