Fillbook
Read full descriptionHide full description
Fillbook is a trading journal for options and futures traders who want a faithful record of what they actually did. Most journals show a four-leg iron condor as four unrelated fills. Fillbook groups executions into positions, follows rolls across expiries, and keeps expiration and assignment visible even when there is no closing fill. Then it gives you a review you can use. Write the rules you trade by and see adherence across your own book: timing, size, DTE, loss limits, profit targets, and cooldowns. Fillbook surfaces recurring behavior without comparing you to an imaginary perfect exit or reporting forgone profit. Export once from your broker—no broker login required. Bring a Robinhood account activity export, a thinkorswim Account Statement export, or another CSV with explicit execution columns. Fillbook keeps the raw source row, normalizes symbols and timestamps, and lets you review uncertain groupings before they become part of your journal. What you get: • Positions instead of disconnected execution rows • Support for verticals, iron condors, strangles, straddles, ratios, and rolls • A review queue for uncertain groupings • Realized P&L from fully closed positions, counted on the closing date • Rule-based adherence review built around your own process • Insights about sequence, structure, and timing grounded in your actual sample • A journal for notes beside the position they explain • Local-first persistence for your journal • A sample book so you can explore the workflow before importing anything Choose a 7-day free trial followed by $2.99/month, or choose $19.99 lifetime access. Monthly access renews until canceled. Lifetime access is a single purchase and never renews. Prices shown by Apple may vary by region. Fillbook is for options and futures traders who want better records, better questions, and less hindsight theater.

Verdict
The clearest difference is in-app purchases: 1DB at none against Fillbook's 2. 1DB also leads on iOS requirement (11.0 vs 17.0). Fillbook's advantage is update cadence (every 8 days vs every 8 months). On price, ads and device support there is nothing between them.
