FillBook - From Fill to Book
Finance
Free · In‑App Purchases
FillBook is a personal stock trading journal designed to help investors record trades, track portfolios, and reflect on the psychology behind every decision.
· Your trades, on a timeline
Log each trading day on a dot-based timeline. Buy, sell, hold, or watch — every day is captured at a glance. Record ticker, execution price, quantity, and risk/reward ratio (R:R), and a daily summary title is generated automatically.
· Track the numbers. And the feelings.
Log your personal Fear & Greed index (Extreme Fear · Fear · Neutral · Greed · Extreme Greed) alongside every trade. Look back not just at what you traded, but how you felt when you made the call.
· Portfolio at a glance
Monitor unrealized gains and losses on current holdings, and review the full trade history of every stock you've ever traded — all in one screen. Supports both Korean markets (KOSPI · KOSDAQ) and US markets (NYSE · NASDAQ).
· Your data stays yours
All records are stored locally on your device. Enable iCloud sync to keep your journal seamlessly updated across devices sharing the same Apple ID — no account registration, no server uploads, no exceptions.
Cut through the noise. Fill your book.
