Writ
Read full descriptionHide full description
Writ is a decision journal. You write the call down before you know how it ends, and Writ finds out whether you were right. Most decisions vanish the moment you make them. The reasoning fades, the outcome gets rewritten in memory, and your gut never has to answer for anything. Writ keeps the record straight. HOW IT WORKS 1. Log the decision. A plain statement of the call, the options you see, and how sure you are. 2. Set a review date. Writ reminds you when it arrives. 3. Answer honestly. What actually happened sits next to what you expected. 4. Watch your calibration sharpen, decision by decision. WHAT YOU CAN LOG • The situation and the options you considered, each with the odds you'd give it • Your confidence, the stakes, and the mood you decided in • A tripwire: the warning sign that tells you a call is going wrong • Tags, so Insights can compare between different categories WHAT WRIT SHOWS YOU • Calibration: every dot is a call, your confidence against reality • Forecast sharpness: whether you beat a coin flip • The Forecaster Compass: bias and gut signal as one position • When you say 80%: does it actually happen 80% of the time? • Your top pick: how often your favorite option wins • By stakes and state of mind: where your judgment runs hot Start free with five decisions. Writ Pro removes the cap and unlocks the full insight set, PDF reports, and CSV export. PRIVATE BY DESIGN No accounts. No ads. No third-party anything. Your journal lives on your iPhone, with optional iCloud sync for backup. Writ is an indie app, built by a single developer. Decisions are the one habit under everything else. Keep the receipts.
