Stock Flight Recorder

Log why you buy and sell; future-you grades past-you with data: win rate, risk-reward, strategy card, prediction accuracy. No tips. 100% on-device.

Stock Flight Recorder isn't a charting app, a quote app, or a tip app. Like an aircraft's black box, it records every trading DECISION you make — so later, future-you can grade past-you with data. It's a 100% on-device investing decision journal and personal coach.

Most investors forget why they bought, forget why they sold, never learn the real cause of a loss, and repeat the same mistake. Stock Flight Recorder makes the moment of decision permanent — then turns those records into honest analytics.

HOW IT WORKS • Capture the reasoning before you buy — buy reasons (pullback, breakout, earnings, flows, theme… multi-select), a one-line thesis, target / stop / expected holding period, a conviction slider (0–100%), a 1-month prediction, your emotion, and a "letter to your future self" (why you bought + what would prove you wrong). • Your own past answers you at input time — "Your real win rate on recent 90%+ conviction trades: 38%." No server, no AI, just statistics computed on your device. (This is our "AI without AI.") • An automatic review when you sell — alongside sell reasons and emotion, the app auto-scores whether you followed your plan, whether you honored your stop, and whether your prediction was right, then captures a one-line lesson.

THE HONEST ANALYTICS YOU GET BACK • Home dashboard — open positions, win rate, average risk-reward, best & worst strategy, investor level • Strategy report card — win rate, average return and count per strategy (pullback, breakout, value, momentum, theme, earnings) • Prediction accuracy — how often your 1-month calls were right, split into up-calls and down-calls • Conviction calibration — do you actually do better when you're sure? Win rate by conviction band • Emotion analysis — win rate by emotion (excited, anxious, neutral…) • Discipline rate — the share of trades where you actually honored your own stop / plan • Investor type & level — an auto-generated investor personality and a novice → rule-based → strategic → systematic → master progression
