iPhone
Practice reading price ranges with fictional assets. Explore simulated buy, wait, and sell examples, save scenarios, and learn risk concepts without real trades.
RangeCube is a learning app powered by server-generated fictional price scenarios. It does not display actual stock market prices, track real securities, or place trades.
EXPLORE FICTIONAL ASSETS
Browse 60 fictional assets, SIM001–SIM060. Each has a reproducible 60-step price curve generated mathematically, not copied or derived from a market-data feed. USD amounts are illustrative. Chart steps are not trading dates.
LEARN THE PRICE MAP
Compare simulated prices with example buy and sell ranges. Explore buy, wait, and sell scenarios, understand the chart marker, and practice stop-loss calculations. All ranges, actions, and example scores are educational illustrations, not real-world predictions.
SAVE SCENARIOS
Five starter scenarios are included. Basic lets you save 1 additional fictional asset. Optional monthly Plus and Pro subscriptions increase the additional saved-asset limit to 10 and 50. All scenarios can be browsed without upgrading. Subscriptions do not provide real market data or trading signals. Your simulation watchlist syncs with your account.
BUILD YOUR UNDERSTANDING
Learn about price ranges, trend limitations, position sizing, and risk. The app does not execute simulated or real orders, hold money, or promise investment returns.
SUBSCRIPTIONS
Payment is charged to your Apple Account at confirmation. Subscriptions automatically renew unless canceled at least 24 hours before the current period ends. Renewal is charged within 24 hours before the period ends. Manage or cancel in your Apple Account settings. Prices are displayed before purchase.
IMPORTANT
All displayed prices are simulated, not actual market prices. For educational use only, not investment advice. An internet connection is needed for accounts, scenarios, saved assets, and subscription verification.
