FREE TO START The Option tab, Calculator, 11 starter strategies, and first 3 lessons are free. OptionGreeks Pro is a one-time purchase, not a subscription, unlocking all 37 strategies, all 10 lessons, heatmap and animation features, unlimited saves, and AI features. Optional tips support development but do not unlock features. OptionGreeks is an educational tool. Nothing in this app is financial advice, and nothing here predicts what any market will do.
