Options trading demands precision, disciplined risk management, and a clear understanding of probability. Whether you're selling premium, constructing spreads, or executing directional strategies with calls and puts, Mantis gives you a private, on-device journal to track every contract, dissect your Greeks, and refine your strike selection over time. Unlike generic note-taking apps or cloud-based platforms, Mantis stores all your trade data locally on your iPhone—no syncing to external servers, no cloud backup, and no third-party access to your strategies. Review your expiration outcomes, theta decay patterns, and assignment history in one secure place, helping you build a repeatable process grounded in your actual results, not conjecture.

Log strike prices, expiration dates, option type (call/put), and the specific strategy (iron condor, vertical spread, straddle) for every position. Attach screenshots of your Greeks at entry, and tag trades by underlying, helping you isolate which tickers and strategies perform best for your style.
Record the credit or debit for each spread, track max profit and max loss, and note your breakeven points. Over weeks and months, compare your realized returns against your initial probability estimates to identify where your risk-reward assumptions align—or diverge—from actual outcomes.
Document whether contracts expired worthless, were closed early, or resulted in assignment. Note your exit timing and any roll decisions. This history reveals patterns in your profit-taking discipline and helps you refine when to take profit versus letting theta work.
Mark trades opened around earnings, ex-dividend dates, or high-IV events. Add context about implied volatility rank at entry. Reviewing these annotations shows you which volatility environments suit your strategies and when you might be overpaying for premium or underestimating tail risk.
All your trade logs, P&L stats, and strategy notes live exclusively on your iPhone. Mantis does not sync to iCloud or upload data to any cloud service, ensuring your options playbook and risk parameters remain private and under your sole control.
View cumulative statistics across all your options trades: total premium collected, average days-to-expiration held, and win rate by strategy type. Use these metrics to validate your edge, adjust position sizing, and focus on the setups that consistently deliver profitable risk-adjusted returns.
Yes. Mantis lets you add detailed notes and tags for each trade, so you can describe all four legs of an iron condor, attach screenshots of your position, and label it accordingly. Over time, filter by strategy tag to review performance across your spreads, straddles, and other multi-leg constructions.
You log every outcome manually: whether you closed before expiration, were assigned shares, or let contracts expire worthless. Add notes explaining your exit rationale—profit target hit, tested short strike, or defensive roll—so you can analyze your decision-making patterns trade by trade.
No. Mantis is a journal, not a pricing engine. You capture the Greeks and IV from your broker or analytics platform by typing them into your trade notes or attaching screenshots. This manual step ensures you stay engaged with the data that matters most to your options strategy.
No. Mantis stores all journals, trades, and images locally on your iPhone only. There is no iCloud sync, no cloud backup, and no remote server involved. Your options strategies, strike selections, and P&L history remain entirely private and under your control.
Yes. Tag each trade by ticker and strategy, then use Mantis's filtering and stats features to group trades by symbol, expiration cycle, or date range. This helps you identify which underlyings offer the best risk-reward for your chosen expiration windows and volatility targets.
