WE DON'T PRETEND TO BEAT THE MARKET A 90% accuracy claim sounds great. KOSAK's models usually land near 50% — about a coin flip — and we print that number right next to every prediction, updated as new data arrives. That honesty is the product. KOSAK was built by a developer who works with machine learning for a living, and the goal was never to pick trades for you. It's to hand you real signals, real hit rates, and the context to make your own call. WHAT'S INSIDE AI Outlook Score Moving averages, RSI, MACD and volume are combined into a single bullish / neutral / bearish read you can grasp in a second — with the reasoning behind it visible, not hidden. On-device deep learning A neural network trains per ticker, right on your iPhone. Its walk-forward hit rate is published as measured — flattering or not. Server-side ML An additional signal trained across many assets at once, for a second opinion that doesn't depend on one chart. Self-audited backtests Every model is replayed against historical data and the resulting accuracy is shown raw. No cherry-picked windows. Forecasts and pattern matching Next-candle and longer-horizon projections, plus a search through past price history for setups that resembled today's. CHARTS THAT DO REAL WORK - Candlestick chart with the AI projection line on the same screen - Drawing tools: trend lines, horizontal levels, Fibonacci retracements, volume-by-price zones - Timeframes from minutes to hours, days, weeks and months - Bitcoin, Ethereum and altcoins from Binance, plus US stocks; Korean markets are included as well ALERTS THAT FIRE WITH THE APP CLOSED - New listing detection for Binance crypto and US stock IPOs - Target price alerts for anything on your watchlist - Optional Telegram digests of your tracked tickers TRADING JOURNAL Log buys, sells and averaging down. KOSAK keeps your average cost and running P&L automatically, then points out the emotional patterns — revenge entries, panic exits, position sizing that drifts. MARKET CONTEXT Fear & Greed Index, total market capitalization, BTC dominance, and the US CPI / PPI calendar, with plain-language notes on how a headline may ripple through the market. LEARNING CENTER Start at "what is a candlestick" and work up through indicators, chart structure and strategy. Crypto and equities, no jargon left unexplained. BUILT THE WAY IT SHOULD BE - Free to use - No account required — sign in only if you want to sync across devices - Dark theme, passcode lock - Available in 14 languages WHAT KOSAK IS NOT KOSAK does not execute trades, hold a wallet, custody funds, move money, or provide investment advice. There is no brokerage connection and no order book. It reads public market data, runs models on it, and shows you the results — including how often those models have been wrong. No model can promise certainty. We'd rather show you the odds. DISCLAIMER KOSAK is provided for informational and educational purposes only. Nothing in the app constitutes investment, financial, legal or tax advice, and no output is a recommendation to buy or sell any asset. Model accuracy is typically close to 50%, past performance does not indicate future results, and any forecast may be wrong. Cryptocurrency and equity markets are volatile and you can lose money. All investment decisions, and the outcomes of those decisions, are your own responsibility.
