No phone number, no brokerage account, no broker on the other end. Rehearse buying, holding and selling with practice money, against your own numbers. Understudy is an educational investing simulator. It uses practice money only — no real accounts, no real trades, and nothing in it is investment advice. Most people learn investing the expensive way: with real money, on a real day, with no idea what a limit order or settled cash actually means until it costs them. Understudy lets you rehearse first. There's no phone number to give and no brokerage account to open. Understudy starts on its own with an anonymous session, and nobody on the other end is trying to move you into real trades. HOW IT WORKS • Open a practice brokerage account funded with simulated cash. • Browse real fund names and fictional stocks at simulated prices. • Place real-style orders — market, limit, stop, stop-limit — and watch them fill, partially fill, or get rejected, with a plain-English explanation of why. • Advance time a day, a week, or a month. Cash settles, dividends land, markets drop — and when something needs you, the clock stops and tells you what it means for you. • Learn each concept the moment you meet it: bid and ask, buying power, settlement, slippage, cost basis, holding periods, wash sales. REAL ESTATE, START TO FINISH (PREMIUM) • Pick one of 25 real metros. Home prices follow each metro's published house price index; the listings are fictional. • Get pre-approved from your own income and savings, then make an offer: the price, the earnest money, which contingencies to keep, and how fast to close. The seller can accept, counter, or turn you down. • Escrow stops at the inspection, the appraisal, and the closing disclosure. Then own the home month by month, and see what owning returned against renting and investing the difference. THE INTERFACE GROWS WITH YOU Your first order ticket asks three things: buy or sell, how much, and what kind of order. As you learn, timing and the fine print appear — until you're reading the same seven-field ticket a real brokerage shows. YOUR NUMBERS, YOUR SIMULATION Enter your own income, savings, and expenses (self-reported) so every scenario runs against figures that mean something to you. Nothing is verified, and no real account is ever connected. Your figures and progress are kept with your Understudy account so they survive a reinstall. Sign in with Apple or Google to take them to another device, and delete them any time in Settings. WHAT'S FREE • The Stocks path in calm and volatile markets, one practice session at a time • Market and limit orders • Every Stocks lesson, with each term explained when you meet it • Your Activity dashboard and session history • Sync across devices when you sign in PREMIUM UNLOCKS • The Real Estate rehearsal, plus the business and bond paths • Historical replays — practice through 2008 and 2020 • Stop and stop-limit orders • Advance straight to a date • Several sessions running at once • The full Outcome Dashboard: key decisions and alternative timelines Premium is available as a weekly or annual subscription (the annual plan includes a 7-day free trial) or as a one-time lifetime purchase. Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period and are managed in your Apple Account settings. Every price in Understudy is simulated. Bond funds follow the shape of published Treasury yield history, and home prices follow published house price indexes; everything else is generated from calibrated statistics or is fictional. Past or simulated performance never predicts real results. Understudy is not a broker, adviser, or bank, and it can never place a real trade.

Real Estate is here: rehearse buying a home, from pre-approval to owning it, with practice money. REAL ESTATE, START TO FINISH • Pick a market and one of 25 real metros. Home prices follow each metro's published house price index; the listings are fictional. • Get pre-approved from your own income and savings, then browse listings with the full monthly payment on each. • Make an offer: the price, the earnest money, which contingencies to keep, and how fast to close. The seller can accept, counter, or turn you down, and a counter brings you back to your offer. • With your first offer, make a call on how much cash closing will ask for. The closing disclosure answers it. • Escrow stops at the inspection, the appraisal, and the closing disclosure. A contingency you kept can get you a credit, or let you walk away with your earnest money. • Then own the home month by month, through repairs, a tax reassessment, and a refinance window. At the end, see what owning returned against renting and investing the difference. • Real Estate is part of Premium. LEARNING AND TODAY • 26 new concepts, from earnest money to amortization, in five groups in the Concept Library. • Today's decision can come from your own deal, like an appraisal that comes in low. • Your Activity lists your deals, open and finished, and opens each one where you left off. Everything in Understudy is still practice money, and nothing in it is investment advice.
