Anyone can buy. The real question is: "Is it actually cheap right now?" Rich Dad checks 79 assets — Korean and US stocks, ETFs, currencies, gold, Bitcoin — against 20 years of data and tells you two things: is today cheaper than usual, and when we bought on days like this, how often was it higher 3 months later. All premium features are free until December 31, 2026. Install now and keep them until then. WHAT IT COVERS (79 ASSETS) - Korea: KOSPI, KOSDAQ, Samsung, SK Hynix, Hyundai, Naver, Kakao, KB Financial, Celltrion - Korean ETFs: KODEX 200, TIGER US S&P 500, TIGER US Nasdaq 100, KODEX Gold, KODEX Semiconductor, KOSEF KTB 10Y, TIGER REITs and more - US: Nasdaq, S&P 500, Dow, NVIDIA, Apple, Microsoft, Amazon, Alphabet, Tesla, Meta, TSMC, Berkshire - US ETFs: VOO, SCHD, SPY, QQQ, SMH, XLK, XLV, XLP, TLT, IEF, TIP, LQD, GLD, VNQ and more - FX: USD, JPY, EUR, GBP, HKD, CHF, THB against KRW - Commodities & crypto: gold, silver, copper, platinum, crude oil, natural gas, wheat, Bitcoin, Ethereum, Solana, XRP HOW "CHEAP" IS DECIDED We measure how far today's price sits below its 180-day norm, then require every paired indicator (KOSPI vs KODEX 200, silver vs the gold/silver ratio, bond ETFs vs US yields...) to agree. If one disagrees, we say nothing. 20-YEAR BACKTEST — WE SPEAK IN PROBABILITIES For every asset: if you had bought on every signal day for 20 years, how often was it higher 3 months later, what was the average return, and how deep did the worst 1-in-20 drawdown go. No "accuracy" or "confidence" claims. It is a record of the past, not a promise about the future. SPLIT-BUY SIMULATOR See how much less you would have been underwater by buying a tranche on each cheap day instead of all at once. Enter your own amount and year — the app shows what it would be worth today. The goal is not to beat the market. It is to lose less. ALERTS YOU CAN AUDIT Get a push when a watched asset enters its buying zone. One screen shows which alerts are live, when they expire and whether they have ever fired. DIVIDEND CALENDAR & IPO CALENDAR - Dividend calendar — see when and how much your holdings pay, by month. Confirmed and estimated payouts are shown separately; assets without data say "no data". - Korean IPO subscription calendar — updated every day. - Economic calendar — FOMC, CPI, jobs, earnings for the next 60 days THE REST OF A DAD'S MONEY - 44 calculators — take-home pay, pension tax savings, DSR, FIRE, FX, gold tracker, net worth - Guru portfolios — what Buffett and Dalio hold right now - Template portfolios — All Weather, 60/40 and Permanent, filled with today's readings FOR YOU IF - You hesitate every time: "should I buy now?" - You dollar-cost-average into pensions, ISAs or US stocks - You want the USD/KRW or JPY/KRW exchange timing in numbers, not gut feel - You invest by rules, for the 10-year long game PHILOSOPHY Wealth is a 10-year game, not a 1-year one. Not winning every trade — just not losing, by the odds. Cheap does not mean it will rise. We simply buy cheap and buy in parts.
