Finn
Finn doesn't teach you the stock market. It makes you feel it.
Now in TestFlight alpha. The first 1,000 testers get in.
The idea
A flight simulator for the stock market.
Pilots don't learn to fly by reading about turbulence. They log hours in a simulator, crash a hundred times, and walk away every time. Finn is that, for investing. You trade real market history with play money, feel a real crash hit your portfolio, and build the instinct no chart or definition can give you. The understanding comes after the feeling, never before it.
Long or short
Make money when the market falls, too.

A trader's career
Nine tiers, rookie to Market Legend.
Feel it
Campaign
Ten chapters of market history, each level a different test built from 21 kinds of scenario. Survive a crash, hedge a falling position, claw back from deep in the red. No tutorials. Stars reward how you actually traded, not what you memorized.
Then know it
Academy
When you want the why, a mentor walks you through it. Twenty-three lessons take you from reading a chart to running Warren Buffett's 2008 playbook, then hand you the 2020 crash to trade yourself and compare your moves to the legend's.
Features
Real history, not random charts
Nineteen market eras built from real historical prices, 1970 stagflation through the 2024 AI boom. Every crash and rally actually happened.
Six ways to play
A 10-chapter campaign, a mentor-led Academy, daily and curated challenges, a free-play sandbox, and a tutorial to get you started.
Pro tools, paper money
TradingView-style charts, real SEC financial statements, and an on-device AI analyst on iOS. Go long or short with zero real risk.
Finn is a time machine with a brokerage account. Pick a moment in history, get a stake of paper money, and trade it forward one day at a time. The prices are real. The crashes are real. The only thing simulated is your money.
The core loop
Every mode runs on the same engine: real historical prices, played forward day by day.
- Drop into history. Nineteen eras, real dates, real prices, from a 1970s oil shock to the 2024 AI boom.
- Make your calls. Buy, sell, short, set a stop-loss. Advance a day at a time, or boost ahead at up to 300x to skip the quiet stretches.
- Live with the outcome. Some trades look brilliant by Friday. Others teach you why the pros sit on their hands. The money is paper. The lesson is not.

Under the hood
Behind the feeling sit 104 real companies under aliased names, with a setting to flip on the real tickers any time. Every stock carries quarterly SEC financial statements, the actual news headlines of its trading days, and, on iOS, an AI analyst you can ask anything.

Finn is a simulation for education and entertainment. It is not investment advice.
