What is in the app
Four screens, each focused on a single job. No live market data, no broker connection, no order routing. All math runs on the device.
- Calculator. Black-Scholes pricing on device with all 17 Greeks, a selected-Greek-vs-spot sensitivity chart, shock rows for spot +/-$5, IV +/-10 vol points, DTE decay, and rate +1%, an IV solver, and position-sizing helpers. Long-press a Greek output for a plain-English "why this number?" explainer.
- Strategies. 29 pre-built payoff structures (long and short calls / puts, straddles, strangles, vertical / calendar / diagonal spreads, butterflies, iron condors, collars, covered calls, plus a custom multi-leg editor). Each shows max profit / loss, breakevens, current Greeks by leg and net, probability of profit, and a T+0 vs expiration payoff overlay. Export any setup as a branded PNG, a Python SDK snippet, or an MCP prompt.
- Portfolio. Educational multi-symbol Greeks aggregator. Build positions manually (no broker connection); the app sums Greeks across legs and runs a 7-preset scenario stress panel across spot, IV, and time, with base / stressed value and P&L from each shock. Intended for learning portfolio behavior, not for tracking a live brokerage account.
- Learn. 40+ visual labs covering Greeks (with a 3D Greek surface), volatility skew, IV vs HV, theta decay, pin risk, earnings IV crush, dealer hedging (GEX intuition), put-call parity, assignment mechanics, and pre-trade pre-mortems. Daily practice ships 7 cards a day with a streak counter and a mastery map ordering the 29 strategies by difficulty tier and prerequisite.
Built for the device
- On-device Black-Scholes engine. All pricing and Greeks math runs locally. The app works in airplane mode. No API calls, no rate limits.
- Math Mode. Toggle the live Black-Scholes formula with d1, d2, N(d1), N(d2), and full number substitution as inputs change.
- iOS share sheet exports. Export any payoff or Greek profile as a branded PNG (strategy name, P&L summary, Greeks, probability of profit).
- Share as code. Export any strategy as a Python SDK snippet or MCP prompt. Continue the analysis with live multi-model pricing in the web app or via an AI assistant.
- Daily practice habit loop. Seven cards per day, streak tracking, and a mastery map. Built for spaced repetition, not screen-time inflation.
How the mobile app and the web platform fit together
The mobile app teaches the framework and runs Black-Scholes pricing and Greek calculations on the device. The web platform applies that framework to live data with the full 17-model pricing surface (Heston, SABR, Local Volatility, Jump Diffusion, Variance Gamma, Monte Carlo, FFT, PDE, Binomial, plus seven exotic-option engines), eSSVI-fit IV surfaces with Dupire local volatility, an automated multi-model regime detector, OI-derived dealer-positioning analytics (GEX, DEX, vanna, charm, vomma), 23 screeners, a 45+ strategy builder, portfolio Greeks aggregation, professional-grade risk analytics, and a day-by-day backtester back to 2007.
Together they cover both ends of an options-research workflow: learn the framework and run quick on-device checks from a phone; apply the framework to live multi-model data from a desktop. Strategies built on mobile can be exported as Python SDK snippets or MCP prompts, then opened in the web app or fed to an AI assistant via the MCP server.
Who it is for
- Beginners. Visual labs explain Greeks, skew, term structure, and dealer hedging before the formulas. The Calculator and Math Mode then show those concepts numerically.
- Intermediate traders. Run a Black-Scholes price and full-Greek read anywhere. Sketch a multi-leg payoff in seconds, stress test it across spot moves, and share the result as a PNG or as code.
- Advanced users. Daily practice cards, mental-math drills, and the mastery map cover the long tail of intuition that does not come from running more models on more tickers.
Important boundaries
- Educational tool. Not investment advice; no buy / sell recommendations, no price predictions.
- No live market data feed in the mobile app. All inputs are user-entered; the web platform is the live-data surface.
- No broker connection, no order routing, no portfolio sync. The Portfolio screen is a manual educational aggregator only.
- On-device pricing is Black-Scholes. Heston, SABR, Dupire / Local Vol, Jump Diffusion, Variance Gamma, Monte Carlo, FFT, PDE, and the seven exotic-option engines run on the web platform against the live calibrated surface.
- Free. No account required. No ads. No tracking.
Android
An Android build is pending Google Play submission. Same on-device Black-Scholes engine, same 17-Greek calculator, same 29 strategy payoffs, same 40+ visual labs and daily practice loop. This page will update with a Play Store link as soon as it is live.
