Trifecta: Judgment & Focus
The 3-habit decision system
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
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.
