Charting, with the quant work already done. KATY is a technical-analysis charting app for US equities and major crypto — candles, timeframes, pan, zoom, scrub — with our own quant models drawn directly on the price instead of left to you to compute. WHAT IS ON THE CHART FORECAST — a time-series foundation model's projected path, with its backtest line and error band, so you can see how the model has actually done on this name before you trust today's read. TURTLE — trend state made visual: Donchian entry and exit channels, a 2xATR stop, held-position bands, and a per-window backtest. GEX — gamma exposure by strike, drawn against price, with call and put walls and the expected move. SPREAD — credit-spread structure over price: strike lines, ROI, probability, credit and max loss, with leg detail. TODAY — every long and short the engines currently have, ranked, with the time left on each. Tap a row to land on the chart behind it. HOW IT WORKS Pick any ticker or tap a symbol chip. Switch timeframes. The overlays follow. Your watchlist syncs across devices, and the trend screener describes only the names you actually track. Every screen is read-only. There is no order entry, no broker connection, no account linking, no wallet, and no trading of any kind — KATY is a chart you read, not a place you trade. Charts and model overlays require KATY Premium, available in the app as an auto-renewable subscription: KATY Premium Monthly at $9.99 per month, or KATY Premium Annual at $59.99 per year. Payment is charged to your Apple Account at confirmation of purchase. A subscription renews automatically unless cancelled at least 24 hours before the end of the current period, and you can manage or cancel it in Settings > Apple Account > Subscriptions.

yPredict turns noisy crypto markets into a clear, at-a-glance forecast. Instead of trading, yPredict shows you where the market may be headed — powered by a panel of AI models that score every major coin for direction, confidence, and expected move. WHAT YOU GET • AI price forecasts for Bitcoin, Ethereum, Solana and hundreds of coins • A daily market outlook — how bullish or bearish the market looks right now • Per-coin forecasts in plain English: bullish, bearish or neutral, a confidence score, and how many models agree • Interactive charts across 24H, 7D, 30D and 90D horizons with a projected target range • A models leaderboard with real, tracked accuracy over hundreds of past calls • Custom watchlists so you follow only the coins that matter to you • Price and AI-signal alerts — get pinged the moment a model flips bullish or bearish MULTIPLE AI MODELS, ONE VIEW Every forecast blends independent models — momentum, sentiment, macro regime, volatility and on-chain flow — so you see not just a number, but how strongly the models agree. Compare models side by side and check each one's track record before you trust it. yPredict PRO Upgrade to Pro to unlock every model on every coin, all forecast horizons, side-by-side model comparison, AI-signal alerts, unlimited alerts and watchlists, and full track records and backtests. Premium model add-ons go even deeper. yPredict Pro is an auto-renewing subscription (monthly, quarterly or yearly). Payment is charged to your Apple ID; it renews automatically unless canceled at least 24 hours before the period ends. Manage or cancel anytime in your App Store account settings. VIEW-ONLY BY DESIGN yPredict is a research and information tool. It does not offer trading, custody, or brokerage, and never touches your funds. Forecasts are probabilistic and for informational purposes only — they are not financial, investment, or trading advice. Crypto markets are volatile; always do your own research.
