Trifecta: Judgment & Focus

Most habit apps measure motion. Trifecta measures whether you're getting better at the things that actually decide outcomes. The whole app rests on one idea: success ≈ Judgment × Time × Luck Each of the three habits trains one of those variables — ten minutes a day, total. No feeds, no coins, no levels. Just the loop that compounds. PREDICTION JOURNAL — sharpen your judgment (3 min) Write a falsifiable prediction with a confidence level and one line on why. On the due date you score it right or wrong. Memory rewrites itself; ink doesn't. Over weeks you learn exactly where your judgment is trustworthy and where it reliably fails. KILL LIST — win by subtraction (5 min) Each evening, name the one thing that, if it vanished, nothing important would break. When the same time-waster appears three times in a week, the app flags it: KILL IT. The very successful win by cutting, not adding. DAILY EXPOSURE — widen your luck (2 min) Luck has a surface area: what you do times how many people know about it. Once a day, do one outward act — message, publish, ship, or ask. One tap to log it. THE CALIBRATION CHART The most important screen in the app. It plots your stated confidence against your real hit rate. If your "70% sure" calls come true 40% of the time, you're overconfident — and now you know by how much. The feedback loop almost no one ever gets. BUILT TO GET OUT OF YOUR WAY • Open, log, and close in under 60 seconds • One screen per habit, one action per screen • Two gentle reminders a day, then silence — no other notifications, ever • Forgiving streaks, because perfectionism kills habits • A Graveyard of everything you've killed • An exposure history that shows your luck surface growing PRIVATE BY DESIGN • 100% local — your data stays on your device • No account, no sign-up, no email • No ads, no tracking, no social feed • One-tap export to plain JSON The anti-trap rule, baked in: keep the system stupid simple. Fancy dashboards are procrastination wearing a productivity costume. Internal, internal, external. Are my bets right? Are my hours on the right bets? Can the world find my bets? Ten minutes a day. Start your first prediction.
